Cleveland, Alaska: another small explosion 15 March 2012

Posted by admin in activity reports, Alaska, Cleveland, eruptions, Iliamna, United States.

Cleveland volcano in the Aleutians had another small eruption on the afternoon of 13 March, reports the Alaska Volcano Observatory, the third such event in a week (the previous eruptions were on 7 March and 10 March). The AVO status report, issued on 14 March at 1134 local time (1934Z) describes what happened:

Yesterday afternoon at approximately 2:55 pm AKDT (22:55 UTC), AVO infrasound and seismic networks detected a small explosion at Cleveland. Clouds prevented a clear view of the volcano at the time of the explosion, however, ash was not observed rising through the cloud deck suggesting relatively minor ash emission.

The Volcano Alert Level for Cleveland remains at Watch, the Aviation Colour Code at Orange. The same report notes that seismicity remains elevated at Iliamna volcano (which remains at Yellow/Advisory).
