AVO has received no other reports of activity at the volcano. Sudden explosions of blocks and ash remain 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. There is no real-time seismic monitoring network on Mount Cleveland and AVO is unable to track activity in real time. http://www.avo.alaska.edu/activity/Cleveland.php John Power, Scientist-in-Charge, USGS jpower@usgs.gov (907) 786-7497 Jeff Freymueller, Coordinating Scientist, UAFGI jeff.freymueller@gi.alaska.edu (907) 378-7556 Volcano Alert Level=ADVISORY Aviation Color Code=YELLOW Cleveland volcano Alaska Aleutians 52.8222 -169.945 CAVW=1101-24-
