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.
