Alert level raised for Alaska volcano
ANCHORAGE - Increased earthquake activity has again prompted scientists to raise the alert level for Alaska's Mount Redoubt volcano.
Geologists at the Alaska Volcano Observatory said yesterday that seismic activity had increased over the past two days. Yesterday morning, 40 to 50 earthquakes were being recorded every hour.
Scientists said conditions may evolve rapidly and culminate in an eruption within days to weeks at the volcano, which is roughly 100 miles southwest of Anchorage.
A steam plume rising about 1,000 feet above the mountain peak was observed Saturday.
The volcano observatory had warned in late January that an eruption of Mount Redoubt could occur at any time.
The observatory lowered an earlier alert last week. A brief escalation of volcanic tremors, as well as a steam and ash plume, had prompted scientists to raise the alert level.
