USGS Volcano Hazards Program Volcano Update
AVO update page and observatory web site
Seismicity remains slightly above background. Satellite images of the volcano during most of the week were cloudy. No anomalous activity was detected in partly clear satellite data on Sept. 10.
The current level of activity does not indicate an imminent or certain eruption. Seismic activity, along with gas emissions, appear to be declining gradually. A similar seismic swarm occurred at Iliamna Volcano in 1996-1997 and was not followed by eruptive activity. Prior to an eruption, AVO would expect to see a significant increase in earthquake activity beneath the volcano.
