Iliamna volcano (Cook Inlet (SW Alaska)) activity update: decreasing seismic activity
Saturday Aug 11, 2012 08:12 AM | BY: T
No unusual activity has been observed or reported at Iliamna Volcano over the past week.
The current level of activity at Iliamna does not indicate an imminent or certain eruption. Seismic activity appears 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.
