USGS Volcano Hazards Program Volcano Update
AVO update page and observatory web site
Cloudy conditions have obscured satellite views at Cleveland Volcano during the past 24 hours. No other observations of unusual activity at Cleveland have been reported.
Additional sudden explosions of blocks and ash are possible with little or no warning. It is possible for associated ash clouds to exceed 20,000 feet above sea level. If a large ash-producing event occurs, seismic, infrasound, or volcanic lightning networks should detect the event and alert AVO staff. There is no real-time seismic monitoring network on Mount Cleveland so AVO is unable to track activity in real time.
