Alert level lowered for Alaska volcano

Posted: Thursday, March 19, 2009

ANCHORAGE - The alert level for Alaska's Mount Redoubt has again been lowered, but scientists expect the volcano to tremor and emit gasses for months.

The Alaska Volcano Observatory lowered the alert Wednesday following a brief escalation of volcanic tremors - as well as a steam and ash plume - during the weekend that raised the alert level.

The volcano is about 100 miles southwest of Anchorage.

Scientists said new magma beneath Redoubt doesn't show "any signs of upward movement," but it shows abnormally high gas emission rates.

Residents of Southcentral Alaska have kept an eye on Redoubt since January, when the observatory warned that an eruption could occur at any time. The alert level was downgraded last week.
