Volcano Update from Archive

The Alaska Volcano Observatory is lowering the Aviation Color Code to YELLOW and the Alert Level to Advisory for Mount Redoubt. Following the steam and ash emission on Sunday, March 15, seismicity has declined to levels prior to that event, and no additional emissions have been observed in web camera or satellite images. The new magma beneath the volcano does not show signs of upward movement at this time. The volcano remains restless with abnormally high rates of gas emission and continued melting of the summit glacier. It is still possible for the current period of unrest to result in an eruption. However, the type of unrest we have observed so far could persist for many months to a year or more and not lead to an eruption. It is possible for conditions at the volcano to change rapidly, advancing from relatively low levels of activity to eruption in time periods as short as 24 hours or less.

AVO will continue to monitor Redoubt closely, but will no longer be formally staffed 24 hours per day. UnknownUnknownUnknownUnknown
