No ash has been detected or reported. While the volcano is active, sudden explosions of blocks and ash remain likely. Associated ash clouds could 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. http://www.avo.alaska.edu/activity/Cleveland.php John Power, Scientist-in-Charge, USGS jpower@usgs.gov (907) 786-7497 Jeff Freymueller, Acting Coordinating Scientist, UAF jeff@giseis.alaska.edu (907) 474-7286 Volcano Alert Level=WATCH Aviation Color Code=ORANGE Cleveland volcano Alaska Aleutians 52.8222 -169.945 CAVW=1101-24-
