USGS Volcano Hazards Program Volcano Update

Volcanic unrest at Iliamna volcano has decreased over the past several months, and the Alaska Volcano Observatory now considers it to have reached typical background levels. Thus, the Aviation Color Code has been reduced to Green and the Volcano Alert Level had been reduced to Normal.

Occasional small earthquakes continue, but at a greatly reduced rate and magnitude relative to the peak of unrest in March 2012. Steam and sulfur gas emissions continue to be observed from sites near the summit during periods of favorable meteorological conditions, but are not unusual at Iliamna.
