Cleveland Stratovolcano Continues to Erupt

Satellite image courtesy of AVO/USGS. 

This satellite radar image is of Mount Cleveland stratovolcano that is located 940 miles southwest of Anchorage on Chuginadak Island in the Aleutian Islands. The image was collected on February 10, 2012 and shows a small lava dome in the volcano's summit crater. The summit crater is about 200 meters across. Recently, the volcano had a brief explosion on March 7th and another on March 9th, both of which likely produced some airborne ash, according to volcanologists. The eruptions may have also removed or partially removed the lava dome that was growing within the summit crater (seen in image above).  

The Alaska Volcano Observatory (AVO) is continuing to keep an eye on Cleveland Volcano, as well as on Iliamna Volcano, (see map below) that is only 140 miles from Anchroage and has seen increased seismic acitivty over recent months.
