USGS Volcano Hazards Program Volcano Update
AVO update page and observatory web site
Slightly elevated surface temperatures indicative of continued low-level unrest were observed in satellite images over the past day. AVO has received no reports of activity from mariners or pilots in the vicinity of the volcano.
Sudden explosions of blocks and ash remain possible with little or no warning. Associated ash clouds could exceed 20,000 feet above sea level. If a large ash-producing event occurs, nearby 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 and AVO is unable to track activity in real time.
