Recent clear nighttime satellite views of Cleveland showed no signs of activity. The lack of a real-time seismic network at Cleveland means that AVO is unable to track local earthquake activity related to volcanic unrest. Short-lived explosions with ash plumes that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery. http://www.avo.alaska.edu/activity/Cleveland.php Michelle Coombs, Acting Scientist-in-Charge, USGS mcoombs@usgs.gov (907) 786-7403 Steve McNutt, Coordinating Scientist, UAF steve@giseis.alaska.edu (907) 474-7131 Volcano Alert Level=ADVISORY Aviation Color Code=YELLOW Cleveland volcano Alaska Aleutians 52.8222 -169.945 CAVW=1101-24-
