The Alaska Volcano Observatory have raised the alert level at Veniaminof volcano to Aviation Colour Code Yellow and Volcano Alert Level Advisory. This reflects a significant change in the seismic behaviour of the volcano, as the AVO’s Volcanic Activity Notice explains:

Over the past day [i.e. 7 May 2009], earthquake activity has increased at Mount Veniaminof volcano. This increase is a significant change from normal background activity … Currently the earthquakes are small in magnitude but are registering across the entire seismic network. Seismicity rates are high and have varied between 5-10 earthquakes per hour during quieter periods to 1-3 earthquakes per minute during more intense activity.

The summit crater is producing steam, in line with its habitual practice, and no ash emissions have been detected. The last large eruption of Veniaminof was a VEI=3 event in 1983. Otherwise its eruptive history is characterized by relatively small eruptions (VEI=1 and 2) on a fairly frequent basis: the most recent was in February 2008.

Another Alaskan volcano to keep an eye on.
