As of February 2, the new lava dome covers the floor of the 650 ft (200 m) diameter summit crater. AVO has received no other reports of activity. The development of a lava dome in the summit crater indicates that sudden explosions of blocks and ash are 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 Chris Waythomas, Acting Scientist-in-Charge, USGS chris@usgs.gov (907) 786-7497 Jeff Freymueller, Coordinating Scientist, UAFGI jeff.freymueller@gi.alaska.edu (907) 378-7556 Volcano Alert Level=WATCH Aviation Color Code=ORANGE Cleveland volcano Alaska Aleutians 52.8222 -169.945 CAVW=1101-24-
