USGS Volcano Hazards Program Volcano Update


AVO update page and observatory web site


No elevated surface temperatures were observed in satellite images over the past 24 hours. AVO has received no other reports of activity at the volcano.

Sudden explosions of blocks and ash are possible with little or no warning and 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. However, for some events, detection may not be possible for several hours. Cleveland volcano does not have a local seismic network and is monitored using only distant seismic and infrasound instruments and satellite data.
