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.
