USGS Volcano Hazards Program Volcano Update

AVO update page and observatory web site

No elevated surface temperatures were observed in satellite images throughout the week. We have received no other reports of activity at the volcano.

Sudden explosions of blocks and ash are still possible with little or no warning. Ash clouds, if produced, could exceed 20,000 feet above sea level. If a large ash-producing event occurs, nearby seismic, infrasound, or volcanic lightning networks should alert AVO staff quickly. However, for some events, a delay of several hours is possible. Cleveland volcano does not have a local seismic network and is monitored using only distant seismic and infrasound instruments and satellite data.
