Like a giant fist punching through the earth, a 1,000-foot long section of the beach below Bluff Point rose up 20 feet from the tidelands sometime last Friday or late Thursday, pushing boulders up from the ocean bottom, cracking sandstone slabs and toppling rocks upside down.
Below Bluff Point, a new fissure opened up at the base of the 800-foot high cliff. The uplift could be a re-activation of a landslide that happened perhaps 12,000 years ago.
"There was just beach before," said Ron Hess, who lives on Bluff Road above the new uplift. "Now there are tidal pools."You can see a rock circle," said Marilyn Hess. "All you used to see was one big rock, and now you can see this uplift of rock."Scientists don't know exactly what caused the uplift. It would take an earthquake over magnitude 7 to cause an uplift that high, said Peter Haeussler, a geologist with the U.S. Geological Survey in Anchorage.

Sun leaves Earth wide open to cosmic rays

2009-06-27T10:43:00.005+01:00

The sun protects us from cosmic rays and dust from beyond the solar system by enveloping us in the heliosphere - a bubble of solar wind that extends past Pluto. These cosmic rays would damage the ozone layer, and interstellar dust could dim sunlight and trigger an ice age. However, when the solar system passes through very dense gas and dust clouds, the heliosphere can shrink until its edge is inside Earth's orbit.

Saudi Arabia evacuates 5 villages in volcano scare - 5.6 earthquake

2009-05-20T00:22:00.001+01:00

RIYADH (Reuters) - Saudi authorities evacuated five western villages on Monday after tremors hit a volcanic region in the past weeks raising concerns of possible eruptions.

"There was a large quake, the largest so far," Ahmed al-Attas, vice president of the Saudi Geological Survey (SGS), told Reuters after civil defence officials evacuated the villages near the town of al-Ais.

Attas was referring to a 4.68 earthquake, which hit the region on Sunday. Al-Ais, 150 km (100 miles) northeast of the Yanbu on the Red Sea, is not close to the world's top oil exporter's oil and petrochemicals facilities.

The region lies on a fault line, according to SGS, which declined to comment on current magma levels, but newspapers reported that in the past few days magma levels had risen to 4 km (2.5 miles) below the surface from 8 km.

Fears of an eruption in dormant volcanoes in al-Ais have sent panic stricken residents voluntarily fleeing to the holy city of Medina and Yanbu last week.

The population of al-Ais, an ancient resting place for caravans travelling between the western and southern cities of the Arabian Peninsula and Syria, is estimated at around 60,000 people.

USGS video still: robust brown plume associated with a hybrid seismic event at 11:03 am

The Hawaiian Volcano Observatory on the Big Island of Hawaii has released video of a robust brown plume associated with a "hybrid seismic event" on the summit of Kilauea at 11:03 am.

The HVO website says brown plumes like this one have appeared occasionally throughout the past year of eruptive activity at the summit, and are often associated with rockfalls.

According to the HVO daily update, Wednesday's activity started with at least two more dusty plumes followed by a larger collapse at 11:03 am and a large, dense, brown plume; there were several more brown plumes over the next two hours before settling to a white plume moving southwest from the crater.

Geologists spot steam plume over Redoubt

2009-03-21T19:39:00.000Z

ANCHORAGE, Alaska — Alaska's Mount Redoubt is again drawing attention because of its potential for an explosive volcano.
Geologists at the Alaska Volcano Observatory say there's a steam plume rising about 1,000 feet above the mountain roughly 100 miles southwest of Anchorage. No explosive or ash activity such as occurred last Sunday has been identified and the observatory has not raised the warning level for the mountain.

Bubbles of warming, beneath the ice

2009-02-22T17:50:00.003Z

As permafrost thaws in the Arctic, huge pockets of methane -- a potent greenhouse gas -- could be released into the atmosphere. Experts are only beginning to understand how disastrous that could be.
Methane (CH4) has at least 20 times the heat-trapping effect of an equivalent amount of carbon dioxide (CO2). As warmer air thaws Arctic soils, as much as 55 billion metric tons of methane could be released from beneath Siberian lakes alone, according to Walter’s research. That would amount to 10 times the amount currently in the atmosphere.
At 32, Walter, an aquatic ecologist, is a rising star among the thousands of scientists who are struggling to map, measure and predict climate change. Parts of her doctoral dissertation on Siberian lakes were published in three prestigious journals in 2007: Science, Nature and Philosophical Transactions of the Royal Society.
According to one of her studies, methane emissions from Arctic lakes were a major contributor to a period of global warming more than 11,000 years ago.
"It happened on a large scale in the past, and it could happen on a large scale in the future," says Walter, who refers to potential methane emissions as "a time bomb."

Redoubt ready to blow?: Volcano upgraded to 'orange' status

2009-01-27T02:21:00.002Z

Mount Redoubt has shaken scientists at the Alaska Volcano Observatory in Anchorage into initiating a round-the-clock watch and an elevation of the Aviation Color Code to orange.

A report issued by AVO at 4:30 p.m. Sunday warned, "The current activity at Redoubt could be precursory to an eruption, perhaps within hours to days."

"Not to panic people, but this could spin up that quickly, and we want to give people the possibilities," Dave Schneider, a volcanologist with AVO, said Sunday evening.

He reported a decrease in seismic activity through the afternoon Sunday.

"Seismicity has declined compared to this morning, though it is still elevated," he said.

Possible natural explanation found for West Antarctica's warming

2009-01-25T19:35:00.002Z

South Pole - In 2008, scientists from the British Antarctic Survey reported a layer of volcanic ash and glass shards frozen within an ice sheet in western Antarctica [the same place the one degree Fahrenheit warming]. The volcano beneath the ice sheet "punched a hole right through" due to its heat and force. This geologic event (a volcano) may prove to be the source of the recent warming seen in West Antarctica in what has otherwise been reported as a 50-year cooling trend seen in East Antarctica.

Dr. David G. Vaughan of the British Antarctic Survey said, "This is the first time we have seen a volcano beneath the ice sheet punch a hole through the ice sheet."

From The New York Times:
"Heat from a volcano could still be melting ice and contributing to the thinning and speeding up of the Pine Island Glacier, which passes nearby, but Dr. Vaughan doubted that it could be affecting other glaciers in West Antarctica, which have also thinned in recent years. Most glaciologists, including Dr. Vaughan, say that warmer ocean water is the primary cause."

Heavy snowfall on Ras Al Khaimah's Jebel Jais mountain

2009-01-25T19:19:00.003Z

Ras Al Khaimah: Snow fell heavily on the mountains of Ras Al Khaimah on Friday night, leaving the Jebel Jais range covered in a thick white blanket of snow.

The extreme cold spell brought the temperature on top of the Jebel Jais mountain cluster, situated at a height of 5,700 feet, to as low as -3 degree Celsius on Friday night, as the snow blanketed an area extending over 5kms.

Major Saeed Rashid Al Yamahi, Manager of the Air Wing of RAK Police, who flew a helicopter to the top of the Jebel Jais mountain, said that the entire area was covered with 10 cm of snow.

Earth's Magnetic Field Changes Climate

2009-01-13T23:18:00.000Z

Jan. 13, 2009 -- The Earth's climate has been significantly affected by the planet's magnetic field, according to a Danish study published Monday that is unlikely to challenge the notion that human emissions are largely responsible for global warming.

"Our results show a strong correlation between the strength of the Earth's magnetic field and the amount of precipitation in the tropics," one of the two Danish geophysicists behind the study, Mads Faurschou Knudsen of the geology department at Aarhus University in western Denmark, told the Videnskab journal.

Svensmark's theory, which pitted him against today's mainstream theorists who claim carbon dioxide (CO2) is responsible for global warming, involved a link between the earth's magnetic field and climate, since that field helps regulate the number of GCR particles that reach the earth's atmosphere.

"The only way we can explain the (geomagnetic-climate) connection is through the exact same physical mechanisms that were present in Henrik Svensmark's theory," Knudsen said.

"If changes in the magnetic field, which occur independently of the Earth's climate, can be linked to changes in precipitation, then it can only be explained through the magnetic field's blocking of the cosmetic rays," he said.

The two scientists acknowledged that CO2 plays an important role in the changing climate, "but the climate is an incredibly complex system, and it is unlikely we have a full overview over which factors play a part and how important each is in a given circumstance," Riisager told Videnskab.

Catastrophic Coincidence: Second Ever Example Of Contemporaneous Meteorite Impact And Flood Volcanism Discovered

2009-01-13T01:12:00.005Z

ScienceDaily (Jan. 7, 2009) — Scientists have discovered only the second example of a meteorite impact that occurred at the same time as massive volcanic activity, in research published in the Journal of the Geological Society the week of Jan 12. The first time such a coincidence was observed, at the Cretaceous-Tertiary boundary, was the catastrophic event thought to be responsible for the extinction of the dinosaurs, 65 million years ago.

Did Earth's Twin Cores Spark Plate Tectonics?

Michael Reilly, Discovery News

Jan. 6, 2009 -- It's a classic image from every youngster's science textbook: a cutaway image of Earth's interior. The brown crust is paper-thin; the warm mantle orange, the seething liquid of the outer core yellow, and at the center the core, a ball of solid, red-hot iron.

Now a new theory aims to rewrite it all by proposing the seemingly impossible: Earth has not one but two inner cores.

The idea stems from an ancient, cataclysmic collision that scientists believe occurred when a Mars-sized object hit Earth about 4.45 billion years ago. The young Earth was still so hot that it was mostly molten, and debris flung from the impact is thought to have formed the moon.

Haluk Cetin and Fugen Ozkirim of Murray State University think the core of the Mars-sized object may have been left behind inside Earth, and that it sank down near the original inner core. There the two may still remain, either separate or as conjoined twins, locked in a tight orbit.

Three Gorges Dam tested as water rises

2008-12-22T02:00:00.001Z

BEIJING (Reuters) - Rising water levels in China's giant Three Gorges Dam have triggered dozens of landslides in recent months, damaging houses, land and infrastructure worth millions of dollars, state media said on Thursday.
In July, China finished evacuating residents from the last town to be submerged by the massive 660-km (400-mile) long reservoir on the Yangtze River, ending an exodus of some 1.4 million people that began four years ago.
The 2,309-meter-long dam, the world's largest, aims to tame the river and provide cheap, clean energy for the country's rapid development.
But critics say rising water levels in the reservoir are eroding already fragile slopes and triggering landslides which could worsen as levels reach their maximum height next year.
The reservoir's administration began withholding water outflows in September to push the reservoir's water level up to 175 meters.
But since then, the rising water level had "further induced geological harm including landslides and collapsing of the reservoirs' banks," the Xinhua news agency quoted Chongqing government spokesman Wen Tianping as saying.
"(These) have caused damage or created a latent threat to ... infrastructure, land and housing in dam areas above the evacuation line," Wen said.

Discovery Of Warm Plasma Cloak Surrounding Earth, New Region Of Magnetosphere

2008-12-15T22:42:00.002Z

ScienceDaily (Dec. 14, 2008) — A detailed analysis of the measurements of five different satellites has revealed the existence of the warm plasma cloak, a new region of the magnetosphere, which is the invisible shield of magnetic fields and electrically charged particles that surround and protect Earth from the onslaught of the solar wind.

"Although it is invisible, the magnetosphere has an impact on our everyday lives," Chappell said. "For example, solar storms agitate the magnetosphere in ways that can induce power surges in the electrical grid that trigger black outs, interfere with radio transmissions and mess up GPS signals. Charged particles in the magnetosphere can also damage the electronics in satellites and affect the temperature and motion of the upper atmosphere."

Team sets records in simulating seismic wave propagation across the Earth

2008-11-25T23:29:00.003Z

To learn more about the inner sanctum of the earth’s core, seismologists take advantage of one of nature’s most destructive forces: earthquakes. Somewhat like the way a CAT scan images the brain, seismologists track seismic wave patterns from earthquakes to model the structure of the earth’s core. One of the great challenges is to capture the propagation of high-frequency waves, with periods of 1 to 2 seconds, as they travel across the globe. To simulate this activity, seismologists employ a spectral-element application called SPECFEM3D_GLOBE that uses a fine mesh of hexahedral finite elements, pictured here, and high-performance computers.

India launches first lunar probe

2008-10-22T16:37:00.002+01:00

SRIHARIKOTA (India), October 22 (RIA Novosti) - India launched its first unmanned mission to the moon on Wednesday, becoming the third Asian country to do so after Japan and China.

Chandrayaan-1 was carried into space by the Indian-built PSLV-C11 rocket, and will take 15 days to reach the moon. Chandrayaan means "Moon Craft" in ancient Sanskrit.

The lunar mission signifies India's breakthrough into the club of leading space powers, and the liftoff was broadcast live on television across the country.

"This is a historic moment for India," said Madhavan Nair, the head of the Indian Space Research Organization.

The 1,304-kg spacecraft is equipped with 10 scientific instruments to study the moon from a 100-km orbit, and one probe that will slam into the lunar surface hoping to uncover signs of Helium 3, an isotope that may fuel energy generation from nuclear fusion in the future.

Five of the instruments were built in India, while the other six were the result of cooperation with Europe and the United States.

The remote-sensing satellite will create a detailed three-dimensional map of the lunar surface and investigate its chemical composition. The primary goal is the discovery of water, along with magnesium, aluminum, silicon and titanium, and the radioactive elements radon, uranium and thorium.

Viagem ao País Basco

2008-08-26T12:41:00.012+01:00

Alguns meses atrás ficou combinado uma viagem à zona Norte de Espanha. Essa viagem vai começar hoje, com o levantar de uma carrinha alugada, que vai ser a nossa casa nos próximos 13 dias.

É aqui, em casa emprestada, que vou tentar fazer um diário de viagem com fotos, vídeos e histórias do que nos vá acontecendo.

Abraços

Dia 29/08/2008

( Ah e tal, afinal não ) alguns momentos antes de ir levantar a carrinha, decidimos vir de carro, com este carregado até cima, arrancamos direitos a Manzaneda; eram 17h quando saímos de Lisboa, na Régua fizemos a 1ª paragem, seguida de outra já em Chaves. Entre estas localidades durante a viagem foi possível acompanhar uma bela trovoada, coisa que já não via há algum tempo. Chegados a Espanha o nosso destino era Manzaneda mas, ah e tal afinal não, visto que já eram 22h e que chegavam as montanhas com tenda para montar, completamente na escuridão, decidimos ir direitos a nossa 2ª opção
que era Tapia de Casariego. Entrámos em Tapia por volta das 5h da manhã, parámos o carro junto à praia onde dormimos direitos que nem um pau, pois as costas dos bancos não podiam ir mais para trás, acordei com a maior dor de costas da minha vida, depois de uma viagem de 10h dormir mais 5 na mesma posição. Tive de ir colocar gelo nas costas, esta tarefa foi fácil, bastou ir dar um mergulho, a água é um gelo. Neste momento estou em Tapia de Casariego nas Astúrias, ontem foi dia de folia até altas horas, fizemos logo uma data de amizades que nos esperam hoje.
Estou no bar do campismo onde há Internet grátis, mesmo bom, amanhã vamos aos Picos da Europa onde possivelmente não irei ter net, vou tentar dar notícias o mais breve possível.

aqui fica uma imagem de TAPIA DE CASARIEGO

Dia 30/08/2008

ola depois de ter escrito o texto anterior já bem a meio da tarde e quando consegui fazer com que o Nuno sai-se da tenda, fizemos uma visita a praia principal de Tapia por volta das 17h, já com algumas nuvens a chegar fomos à descoberta de mais sítios, foi então que descobrimos uma praia linda mesmo por trás do parque de campismo onde tiramos muitas fotos e acabamos com a bateria da maquina, foi então nessa altura que começou uma espectacular ( tormenta ) e nós sem bateria na maquina. Mais uma vez fomos para a maluqueira da noite pensado que a tempestade já tinha passado, por volta da meia noite e já no centro da vila de Tapia tudo recomeçou era faiscas por todo o lado, sem maquina e já com uns copitos a mais era entrar no bar pedir uma cerveja ver umas ( guapas ) e vir cá para fora ver e ouvir umas trovoadas.
foi uma noite de loucos são 13h e ainda se ouve os trovoes ao longe.

Chaiten Volcano in Chile shows signs of eruption

2008-08-08T23:23:00.004+01:00

Eruptions of smoke and ash from Chile's Chaiten renew fears among population. Chile's Chaiten volcano spews smoke and ash, renewing fears of residents and authorities who witnessed massive eruptions from the volcano in May.

After several weeks of relative calm, Chile's Chaiten volcano, groaned and rumbled on Thursday (July 31), shooting out ash and causing renewed fears among residents and authorities. Regional director of the National Geological and Mine Service, Jorge Munoz, said that the volcano had registered 105 tremors, many with relatively strong intensity coming in at roughly 4.0 on the Richter scale. "Well, there are two scenarios," said Munoz after surveying Chaiten from the air. "One scenario is very concrete - it is that the eruption is ending, the first cycle of the eruption is ending and we can in relation with the high seismic activity that we currently have, have the probability in a hypothesis that a second cycle could begin."

The tropical storm and its remnants will continue moving inland with winds which won't be as strong as they were but will still be gusty in the Houston metro area, along with heavy rain. This is not the same kind of situation as with Allison in 2001, but if one of those bands of torrential downpours gets stuck over a given place it will produce flash flooding, like that which closed I-10 for awhile near Anahuac. Where flooding does not occur the rain will be beneficial, as the region is still in the midst of a drought.

On Friday, 2008 August 01, a total eclipse of the Sun is visible from within a narrow corridor that traverses half the Earth. The path of the Moon's umbral shadow begins in Canada and extends across northern Greenland, the Arctic, central Russia, Mongolia, and China. A partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes northeastern North America, most of Europe and Asia.

Pre-quake changes seen in rocks

2008-07-11T17:03:00.001+01:00

Scientists have made an important advance in their efforts to predict earthquakes, the journal Nature says.

A team of US researchers has detected stress-induced changes in rocks that occurred hours before two small tremors in California's San Andreas Fault.

The observations used sensors lowered down holes drilled into the quake zone.

The team says we are a long way from routine tremor forecasts but the latest findings hold out hope that such services might be possible one day.

"If you had 10 hours' warning, from a practical point of view, you could evacuate populations, you could certainly get people out of buildings, you could get the fire department ready," said co-author Paul Silver of the Carnegie Institution for Science, Washington.

June 30, 2008

Rapid changes in the churning movement of Earth's liquid outer core are weakening the magnetic field in some regions of the planet's surface, a new study says.

"What is so surprising is that rapid, almost sudden, changes take place in the Earth's magnetic field," said study co-author Nils Olsen, a geophysicist at the Danish National Space Center in Copenhagen.

The findings suggest similarly quick changes are simultaneously occurring in the liquid metal, 1,900 miles (3,000 kilometers) below the surface, he said.

The swirling flow of molten iron and nickel around Earth's solid center triggers an electrical current, which generates the planet's magnetic field.

Chile decrees red alert for volcano eruption

2008-07-03T20:12:00.002+01:00

SANTIAGO, July 2 (Xinhua) -- The Chilean regional authorities Wednesday issued a red alert near the erupting volcano Llaima.
The National Bureau of Emergency (Onemi) said the measure includes the creation of a cordoned zone to protect residents from the 50-meter wide lava flow visible from Cherquenco, some 12 km from the volcano.
The volcano erupted Tuesday, forcing the evacuation of 25 people.

A week after perihelion, Comet C/2007 W1 Boattini should now be visible in the dawn sky by observers in the Northern Hemisphere. Preliminary results on Seiichi Yoshida's website indicate that it's now roughly magnitude 5.5 — still near its peak brightness.

So early July is the best time for northerners to see this comet — assuming that your're fanatical enough to get up at 3 or 4 a.m. Few people are likely to see the comet without optical aid, but it should be pretty easy to spot through binoculars as long as your light pollution isn't too bad.

Two new columns of smoke erupted from the Chaiten volcano on Tuesday (June 17) after activity had calmed since late May.

The Chaiten volcano, located some 760 miles (1,123 kilometres) south of the capital Santiago, started erupting on May 2 for the first time in thousands of years, spewing ash, gas, and molten rock.

Area residents were evacuated from the town of Chaiten. The flow of the Blanco river has also increased due to this recent activity.

Cold Irony: Arctic Sea Ice Traps Climate Tour Icebreaker

2008-05-31T00:56:00.002+01:00

27 May 08 – “Cashing in on the panic that has set in with the help of some climate alarmists, tour operators like Quark Expeditions of Norwalk Connecticut are offering polar expeditions catering to that “see it before it’s gone” travel worry. One of them is a trip though the Northwest Passage on a former Soviet Icebreaker called the Kapitan Khlebnikov, a massive 24,000 horsepower Polar Class icebreaker capable of carrying 108 passengers in relative luxury through the arctic wilderness.
Unfortunately, the Kapitan Khlebnikov got stuck in the ice.

One of the passengers wrote: ‘What irony. I am a passenger on one of the most powerful icebreakers in the world, travelling through the Northwest Passage - which is supposed to become almost ice-free in a time of global warming, the next shipping route across the top of the world - and here we are, stuck in the ice, engines shut down, bridge deserted. Only time and tide can free us.’

New Zealand's largest active volcano, Mount Ruapehu in the North Island, has been showing signs of increased activity and scientists are warning it may erupt.

But up on the mountain tourism operators are not too concerned. They are more worried that the media reports have scared off visitors.
Meanwhile newspaper headlines in New Zealand are reading "Restless Ruapehu emits danger signs" and "Molten rock on the move".

Now, in an extensive search of the relatively recent, local universe, University of Colorado at Boulder astronomers said they have definitively found about half of the missing normal matter, called baryons, in the spaces between the galaxies. This important component of the universe is known as the intergalactic medium and it extends essentially throughout all of space, from just outside our Milky Way galaxy to the most distant regions of space observed by astronomers.

The Cosmic Ray-Climate Connection

2008-05-21T15:22:00.000+01:00

Kirkby reports that "diverse reconstructions of past climate change have revealed clear associations with cosmic ray variations recorded in cosmogenic isotope archives, providing persuasive evidence for solar or cosmic ray forcing of the climate." Despite the increasing evidence of its importance, however, he says that "solar-climate variability is likely to remain controversial until a physical mechanism is established." In this regard he discusses two different classes of microphysical mechanisms that have been proposed to connect cosmic rays with clouds, which interact significantly with fluxes of both solar and thermal radiation and, therefore, climate: "firstly, an influence of cosmic rays on the production of cloud condensation nuclei and, secondly, an influence of cosmic rays on the global electrical circuit in the atmosphere and, in turn, on ice nucleation and other cloud microphysical processes." Kirkby reports, in this regard, that "considerable progress on understanding ion-aerosol-cloud processes has been made in recent years, and the results are suggestive of a physically-plausible link between cosmic rays, clouds and climate."

Chinese experts give reasons for magnitude revision of SW China earthquake

2008-05-20T13:13:00.005+01:00

BEIJING, May 19 (Xinhua) -- Experts from the China Seismological Bureau (CSB) said on Monday the magnitude revision of the strong earthquake in southwestern Sichuan Province was due to confirmed statistics from more monitoring stations at home and reference from overseas seismological observatories.

"It is a common practice to revise the magnitude of a major earthquake," said Xiu Jigang, CSB deputy director in an interview with Xinhua.

He explained that scientists had to use statistics from a few monitoring stations to estimate the magnitude of the earthquake as soon as possible. Then as they were able to take reference of statistics from more domestic stations and with the estimated figures by the observatories around the globe, they came to a more accurate conclusion.

The first report by CSB set the magnitude at 7.6 on the Richter scale after the quake hit Sichuan Province on May 12. The quake was shortly upgraded to 7.8. Then the bureau revised the magnitude from 7.8 to 8.0 on Sunday.

The magnitude was revised upward after specialists carried out "real-time and detailed measurements of the quake according to international practices," said Luo Zhuoli, an expert with CSB.

Scientists from the United States first put the magnitude of the tremor at 7.8 and then revised it to 7.9, while their counterparts in Europe revised it from 7.5 to 7.9, and Russia, 8.0.

The quake, claiming 34,073 lives as of 4:30 p.m. Monday and leaving 245,108 injured so far, has caused serious damage to buildings, bridges and other public facilities in an area of more than 100,000 square kilometers.

Comet Boattini: Barely Visible Now, Bright in July?

Serious comet chasers — people who track faint comets with telescopes and binoculars — have been aware of Comet C/2007 W1 (Boattini) for quite a while. It was forecast to become quite bright for a telescopic comet, 6th or perhaps even 5th magnitude, making it visible without optical aid to skilled observers at dark sites.

So far, Boattini has exceeded the brightness predictions by more than a full magnitude. If it keeps behaving like this — and that's a very big if! — it could become quite prominent in July.

Right now, unfortunately, the comet is fairly deep in the southern sky, making it a difficult target from mid-northern latitudes. The best sightings have been from the Southern Hemisphere, where it's already visible without optical aid under ideal conditions. But Boattini has also been spotted by many binocular observers in the southern tier of the United States, particularly Arizona and Southern California.

At the time of writing, the nearly full Moon makes Comet Boattini's faint, fuzzy shape almost impossible to see. But there will be a brief window of visibility after the Moon gets out of the early-evening sky (on May 21st) and before the comet disappears into the Sun's glow in June.

Frog march sparks new quake alarm

2008-05-20T13:10:00.001+01:00

For the second time this month, residents observed a huge migration of frogs and toads, the state-run Xinhua news agency said.
Residents of Zunyi, a southern city that saw little damage in China's huge earthquake last week, noticed the amphibians' march yesterday, Xinhua said, quoting Vice Mayor Zeng Yongtao.
Thousands of residents camped out in fear overnight in downtown Zunyi, the news agency said.
"We don't know what else we can do,'' Zunyi resident Liu Yong was quoted as saying.
Their decision to move outdoors coincided with a warning from seismological authorities that there may be another big aftershock in southwestern China's Sichuan province today following last week's tremor.
The May 12 earthquake - which left more than 71,000 people dead, missing or buried in rubble - also came after reports of unusual movement of frogs and toads.
Internet blogs showed footage of frogs and toads covering the streets of Mianyang in the days before the town in Sichuan province was ravaged by the earthquake.

Frogs Swarmed in China Before the Quake - Now It's California

2008-05-18T23:57:00.002+01:00

In the days prior to the gigantic earthquake that devastated Sichuan province in China, odd swarms of frogs were seen in the streets of cities in the area, and have subsequently been identified as unusual animal behavior of the type that is thought by some geologists to precede earthquakes. Now it has developed that similar frog appearances have been taking place in Bakersfield, California for about two weeks, and nobody is sure why. Strange swarms of frogs also appeared before the 6.9 Loma Prieta Earthquake in October of 1989.
The frogs are emerging from a drainage ditch and are being observed in swarms of hundreds by local residents. Nobody can remember a frog swarm like this in the area. The animals appear to be emerging from a drainage ditch, and it is possible that a lack of natural predators in the water has allowed the overgrowth of frogs.

A more controversial earthquake sign is linear clouds, or clouds that appear arrayed in lines, such as those shown in this photograph, which was taken in Shandong Province, also on May 9, 2 days prior to the Sichuan quake. So far, such clouds have not been observed by Unknowncountry.com correspondents in California.

A Double Whammy? - Antipodal earthquakes

2008-05-16T23:06:00.002+01:00

The NASA finding gives little comfort to those who still believe that volcanism alone did in the dinosaurs. But they are encouraged by a novel "double-whammy" theory suggesting that an impact on one side of the earth could produce massive volcanic activity at the antipode -- a point directly opposite on the far side -- and that the combined effect would cause disaster. Says Jon Hagstrum, the U.S. Geological Survey paleomagneticist who co-authored the theory: "This would be the best way to trigger worldwide mass extinctions because you have both hemispheres affected."

China on alert against quake radiation leaks

2008-05-16T23:02:00.001+01:00

BEIJING (Reuters) - China is on precautionary alert against possible radiation leaks from the deadliest earthquake to hit the country in three decades, according to government website seen on Friday.

The disaster area is home to China's chief nuclear weapons research lab in Mianyang, as well as several secretive atomic sites, but no nuclear power stations.

Minister of Environmental Protection Zhou Shengxian convened an emergency meeting late on Monday, hours after the 7.9 magnitude tremor rocked the southwestern province of Sichuan, and activated the lowest tier of a four-stage system of ranking radiation leaks, the ministry said on its website (www.zhb.gov.cn).

President Hu Jintao flew to Mianyang on Friday, four days after the quake, which is thought to have killed more than 50,000 people, state television and the official Xinhua news agency reported, in an indication the risk was low.

Xinhua didn't say if Hu had inquired about nuclear facilities there.

But nuclear scientists were evacuated from the area as a precaution, a source with knowledge of the evacuation said.

"Everyone was evacuated. No one was left," the source, who requested anonymity, told Reuters.

BEIJING, China - A powerful earthquake in southwest China has killed up to 5,000 people and left as many as 10,000 injured, state media said, as hundreds of children remained trapped in at least eight collapsed schools.

The temblor was felt as far away as Pakistan, Vietnam and Thailand.

An estimated 3,000 to 5,000 people were killed in Beichuan county of mountainous Sichuan province alone after the 7.8 magnitude earthquake hit the region during the early afternoon on Monday, Xinhua news agency said, citing the local government.

Ghosts and smell of victims haunt survivors of the Burma cyclone

2008-05-08T15:24:00.002+01:00

The stench of death hung over the Irrawaddy delta town of Labutta, where the blackened bodies of people and animals, rotting in the tropical heat, were washed aground as Burma’s cyclone floodwaters receded.

Struggling to breathe through the overpowering smells, residents wrapped layers of cloth around their faces and rubbed in balm to mask the odour. Death pervades this town so completely that many said they cannot sleep because ghosts of the cyclone victims torment them. One said: “We can’t sleep at night, because we can hear people shouting at night. Maybe these are the ghosts of the villagers."

Grossly bloated bodies lay strung out along the roads running atop embankments between paddies in a region that was the country’s rice bowl, but is now the centre of one of the world’s worst natural disasters.

One man said: “I cannot describe how I felt when I saw so many dead bodies.”

Active volcano makes hundreds sick in Ubinas, Peru

2008-04-26T13:24:00.002+01:00

Residents in the district of Ubinas, one of three provinces in the southwestern region of Moquegua, are complaining about an active volcano in their district once again. The district of Ubinas is home to Peru's most active volcano, a stratovolcano also known as Ubinas. Townspeople in the area are complaining of migraines and respiratory illnesses which are being attributed to the ash, smoke and toxic gases the volcano is emitting. The gases the volcano is emitting have affected 800 people in the areas of Querapi, Ubinas and Sacoaya - all located in the Ubinas valley, said Jose Fuentes Flores, the regional Civil Defense director.

Giant Underwater Volcano Discovered in Iceland Expected To Erupt At Any Time

2008-04-12T23:33:00.002+01:00

Volcanologist Ármann Höskuldsson from the University of Iceland and a team of scientists recently discovered a giant volcano off Reykjanes peninsula, southwest Iceland, almost as as large as the peninsula itself, and expect it to erupt at any time.

In the center of the volcano there is a caldera measuring ten kilometers in diameter.
“People shouldn’t be surprised if there would be an extensive volcanic eruption underwater there soon. Nothing has happened for hundreds of years and it is in fact only a matter of time before there will be an eruption,” Höskuldsson told DV.
Since the volcano is at a depth of 1,500 meters eruptions would not have any effect on Iceland, except perhaps causing earthquakes.
The volcano’s discovery is considered significant because geographers believed it couldn’t exist in that area. “Such large volcanoes are not located on oceanic ridges. They are always drifting apart and that prevents a volcano from being created. This is why the volcano’s existence came as a surprise,” Höskuldsson said.

Volcanic eruption in 1600 may have caused global cooling

2008-04-12T23:20:00.003+01:00

London, April 12 (ANI): A new study has suggested that a volcanic eruption that happened in 1600 in the Andes mountains may have plunged the world into cold climate chaos.
According to a report in nature News, the eruption of the volcano, known as Huaynaputina, blanketed nearby villages with glowing rock and ash, killing some 1,500 people.
But it may also have had a far wider effect, by injecting sulphur particles high into the atmosphere and disrupting the climate worldwide.
Geoscientists had known that the eruption was big, but the new research addresses for the first time just how it might have changed society the world over.
Were talking about sudden and abrupt change over a very short period of time, said Kenneth Verosub, a geologist at the University of California, Davis. What would that have done to the global agricultural economy? he added.
For their research, Verosub and his coauthor, student Jake Lippman, trawled through historical records of crops, famines and other events in the years just after the Huaynaputina eruption.
According to them, the year 1601 featured several climate discrepancies.
Tree-ring records show that it was the coldest year in six centuries in the Northern Hemisphere - possibly due to the cooling caused by the sulphur particles spewed from the volcano.
The effect was felt on the other side of the globe, where a severe winter caused famine in Russia. Snow blanketed Sweden, leading to record flooding and a poor harvest.

Big Island Officials Prepare for Kilauea Danger

2008-03-31T13:26:00.002+01:00

Hawaii, USA
Big Island Officials Prepare for Kilauea Danger - Levels of toxic sulfur dioxide at the summit are six to ten times greater than before the eruption. "The ten-fold increase of SO2 at the summit makes the total output for the volcano double basically, and the increased hazard from this emission source is, it's closer to where people live and breath and visit than Pu'u 'O'o is." Experts say no one can know exactly what will happen next so they're preparing for the worst. Tradewinds have been pushing the toxic cloud away from the nearest towns but a wind shift could force evacuations. The billowing fumes from Halema'uma'u crater are a growing danger. Even the experts say they are prepared to leave if conditions get too dangerous.
Geologists have been analyzing the steam and gas plume that’s been gushing from Halemaumau crater at the summit of Kilauea since March 11th. They've found something they didn’t expect: the H2O in their test tubes is not from ground water. It's been released from the molten subterranean magma itself. They’re calling it “juvenile water,” and IT'S NEVER BEEN SEEN BEFORE ANYWHERE ON THE PLANET.

This is not a drill: The earth actually is moving beneath western Washington

2008-03-07T21:51:00.000Z

Earlier in the week, seismographs in the southern Hood Canal area began recording bursts of low-level shaking associated with what is called an episodic tremor-and-slip event. If this episode behaves true to form, the tremor will move north beneath the Olympic Mountains and across to Vancouver Island during the next two to three weeks.

This the fifth so-called slow-slip event to be recorded since the phenomenon was discovered in 2002, and it will be the most closely studied such event so far. University of Washington scientists and students are hurrying to deploy a special set of instruments, 100 temporary seismographs set in a close formation in the Olympic mountains, to record the current episode. The temporary stations will augment readings from the permanent seismograph network that covers all of Washington and Oregon.

"We hope to record unprecedented detail as the tremor moves beneath the seismometer array," said John Vidale, a UW professor of Earth and space sciences and director of the Pacific Northwest Seismic Network.

Slow-slip events, or silent earthquakes, occur at a depth of about 25 miles and can last for several weeks. Though they are unfelt by humans, they can release as much energy as a large earthquake.

Since they were first discovered in the Puget Sound region, such events have occurred regularly about every 14 months. The current slow-slip event was expected to start between mid-February and mid-April, and the first evidence that it had begun turned up on Sunday.

Could Volcanic Activity In West Antarctic Rift Destabilize Ice Sheet?

2008-03-07T21:27:00.003Z

About 98 percent of it is buried beneath glacial ice, up to 2.5 miles thick, and bedrock beneath the ice is 2000--3000 feet below sea level over large areas. All of this makes it a difficult region to study.

It is interesting nevertheless, because volcanic eruptions beneath the ice could destabilize the ice sheet, leading to as much as 25 feet of sea-level rise. How likely is it that this could happen is a question scientists have debated for over a decade. LeMasurier addresses the question by comparing the West Antarctic rift with similar areas of crustal stretching elsewhere in the world.

The comparison shows that volcanic activity in rifts is most common where the land is a mile or more above sea level, and rising, which can readily be seen in Antarctica along the Transantarctic Mountains, and in the Pacific coast mountains of Marie Byrd Land. The large sub-sea-level interior of the rift does not, therefore, seem to be a likely place for present-day volcanic activity.

First Evidence Of Under-ice Volcanic Eruption In Antarctica

The subglacial volcano has a 'volcanic explosion index' of around 3-4. Heat from the volcano creates melt-water that lubricates the base of the ice sheet and increases the flow towards the sea. Pine Island Glacier on the West Antarctic Ice Sheet is showing rapid change and BAS scientists are part of an international research effort to understand this change.

Using airborne ice-sounding radar, scientists from British Antarctic Survey (BAS) discovered a layer of ash produced by a 'subglacial' volcano. It extends across an area larger than Wales.

Lead author* Hugh Corr of the BAS says, "The discovery of a 'subglacial' volcanic eruption from beneath the Antarctic ice sheet is unique in itself. But our techniques also allow us to put a date on the eruption, determine how powerful it was and map out the area where ash fell. We believe this was the biggest eruption in Antarctica during the last 10,000 years. It blew a substantial hole in the ice sheet, and generated a plume of ash and gas that rose around 12 km into air."

'Enjoy life while you can'

2008-03-06T21:06:00.002Z

Climate science maverick James Lovelock believes catastrophe is inevitable, carbon offsetting is a joke and ethical living a scam.

"There have been seven disasters since humans came on the earth, very similar to the one that's just about to happen. I think these events keep separating the wheat from the chaff. And eventually we'll have a human on the planet that really does understand it and can live with it properly. That's the source of my optimism."

What would Lovelock do now, I ask, if he were me? He smiles and says: "Enjoy life while you can. Because if you're lucky it's going to be 20 years before it hits the fan."

NASA Baffled by Unexplained Force Acting on Space Probes

2008-03-01T12:17:00.003Z

Mysteriously, five spacecraft that flew past the Earth have each displayed unexpected anomalies in their motions.

These newfound enigmas join the so-called "Pioneer anomaly" as hints that unexplained forces may appear to act on spacecraft.

A decade ago, after rigorous analyses, anomalies were seen with the identical Pioneer 10 and 11 spacecraft as they hurtled out of the solar system. Both seemed to experience a tiny but unexplained constant acceleration toward the sun.

A host of explanations have been bandied about for the Pioneer anomaly. At times these are rooted in conventional science — perhaps leaks from the spacecraft have affected their trajectories. At times these are rooted in more speculative physics — maybe the law of gravity itself needs to be modified.

Mystery hum puzzles geologists

2008-03-01T12:08:00.001Z

Geologists have detected a new continuous seismic signal in the Earth, but its cause is anybody's guess

Listen closely, and you'll hear the Earth humming - in not just one note, but two. The source of this second signal is a mystery.

For around a decade we've known about Earth's quiet "vertical" hum, probably caused by the steady thumping of deep waves on the ocean floor. Now a team in Germany has discovered a second "horizontal" note, too, and nobody knows what's causing this new signal.

They found evidence of a "horizontal" signal at all four stations. The signal migrates by around 1 micrometre one way or the other every three minutes or so, and its horizontal orientation distinguishes it from Earth's "vertical" oscillation. (Geophysical Research Letters)

Though certain events seem to amplify this constant signal - such as earthquakes, volcanoes and large storms - the source is a mystery. "Something entirely new to us is causing this hum," says Spahr Webb of the Lamont-Doherty Earth Observatory in New York, who studied the original hum.

"Something entirely new to us is causing this hum. Its frequency suggests something is 'twisting' the surface of the crust."

Major Volcanic Eruption in Colombia Forces Thousands to Evacuate

2008-01-18T11:53:00.000Z

BOGOTA, Colombia — A volcano erupted violently in southwestern Colombia Thursday, spewing ash miles into the sky and prompting the evacuation of several thousand people living nearby.

There were no immediate reports of injuries or serious property damage after the 14,110-foot Galeras volcano began erupting about 8 p.m. and cascading lava lit up the night sky.
"It's still erupting," Gil said more than two hours after its initial eruption.
Gil estimated that the ash cloud reached five miles into the air.
He called it the most severe eruption of Galeras since the volcano reactivated in 1989.
"Depending on the wind direction it's going to spread ashes over the entire area."
"Most of (Galeras') eruptions are violent and short," he noted. He said Thursday's eruption had produced some lava flows that did not extend far from the volcano's crater.

Chile volcano forces evacuations

2008-01-02T13:49:00.000Z

A volcano has erupted in southern Chile, leading to some 150 people being evacuated from the immediate area.

The Llaima volcano, about 650 km (400 miles) south of the capital, Santiago, produced a huge column of smoke, and threw out lava and ash.
Officials say further evacuations from local villages may be necessary.

Winter storm pounds northeastern United States

2007-12-17T11:33:00.000Z

BOSTON, Dec 16 (Reuters) - A snowstorm that blanketed parts of the Midwestern United States barreled into New England on Sunday, bringing snow, freezing rain and high winds that grounded flights and made driving treacherous.
Roads were slick with snow and ice, and local airports reported hundreds of flights canceled across New England.
Upstate New York received as much as a foot (30 cm) of snow, while the storm spared New York City, leaving only a coating of icy slush. Thousands of people were without power in New Jersey, Long Island and parts of Connecticut.
In New England, about 8 inches (20 cm) of snow fell around Boston, though the precipitation changed to rain across coastal areas by afternoon, according to the National Weather Service.
It dropped more than 10 inches (25 cm) across parts of Maine, New Hampshire, Vermont, Massachusetts and Rhode Island. Forecasters said high winds would continue through the evening and parts of northern New England could receive as much as 14 inches of snow. They warned that with sub-freezing temperatures expected overnight, much of the rain that fell on the region late in the day would turn to ice.
The wintry blast came a week after a Midwest ice storm was blamed for 13 deaths and cut power to hundreds of thousands.

Volcanic Eruption by Vatnajökull Glacier Imminent?

2007-12-17T11:30:00.000Z

Hundreds of small earthquakes have been detected in the region Upptyppingar since Friday last week, located about 20 kilometers east of the volcano Askja and north of Vatnajökull glacier. Experts say a volcanic eruption may follow.

Most of the earthquakes occurred at a depth of 13 to 15 kilometers. If their source moves closer to the surface by a few kilometers, the likelihood of a volcanic eruption increases, Sigthrúdur Ármannsdóttir, a geographer at the Icelandic Meteorological Office, told Fréttabladid.
There were, however, fewer earthquakes in the area yesterday than in the days before, but that may only be a temporary condition, Ármannsdóttir said.
According to Magnús Tumi Gudmundsson, a professor in geophysics at the University of Iceland, the area north of Vatnajökull glacier is volcanically active though there has not been an eruption there for 1,000 years. The volcano Askja last erupted in 1961.

More evacuations ordered as B.C. ice jam grows

2007-12-17T11:26:00.000Z

An ice jam described as unstable and unpredictable forced more residents to leave their homes in Prince George, B.C., on Saturday. About 40 evacuation notices were delivered Saturday morning to people in a low-lying area of the city as officials examined a trail of slushy ice extending for six kilometres along the Nechako River. In total, about 50 evacuation orders have been issued over the past week. Another 12 business owners were ordered to leave, while a number of businesses in a light industrial area along River Road remained closed on the weekend because flooding made them inaccessible.
