AVO update page and observatory web site

Relatively clear weather over the past week provided good satellite viewing conditions of Cleveland. Weakly elevated surface temperatures were recorded at the summit in satellite imagery. There have been no recent changes to the summit lava dome erupted in January 2013. AVO received no other reports of activity.

Cleveland volcano forms the western half of Chuginadak Island, a remote and uninhabited island in the east central Aleutians. It is located about 75 km (45 mi.) west of the community of Nikolski, and 1500 km (940 mi.) southwest of Anchorage. The volcano's most recent significant eruption began in February, 2001 and it produced 3 explosive events that produced ash clouds as high as 12 km (39,000 ft) above sea level. The 2001 eruption also produced a rubbly lava flow and hot avalanche that reached the sea. The most recent minor ash emissions were observed in November 2012.
