Lava dome appears unstable

Posted: Friday, May 29, 2009

Seismic activity remains above background levels at Mount Redoubt and consists of small, discrete earthquakes in the summit region, according to the Alaska Volcano Observatory. AVO scientists report that the lava dome at the summit appears unstable and could fail with little or no warning. Dome failure would likely cause ash emissions to over 30,000 feet above sea level and possible lahars in the Drift River valley.
