USGS Volcano Hazards Program Volcano Update

AVO update page and observatory web site

Increased seismicity characterized by elevated levels of continuous tremor is continuing. Lava fountaining and ash emissions are likely occurring at the intracaldera cone of Veniaminof Volcano. No ash plumes have been observed in satellite images over the past 24 hours and local web camera views of the volcano have been obscured by clouds and fog. AVO has received no reports of ash fall on nearby communities, but this remains a possibility as the elevated levels of seismic activity continue.

If ash fall does occur, the amounts are not expected to be significant and likely will be less than 1/16 inch, although areas within a few miles of the intracaldera cone could receive thicker amounts of ash fall. Information about volcanic ash and its potential effects can be found on the AVO web page (
