Eruption news from Cleveland volcano:

Cleveland volcano (Alaska) activity update: steaming, thermal anomaly from summit crater lava dome

Friday Jul 27, 2012 10:05 AM | BY: T

AVO reported that elevated surface temperatures from Cleveland were detected in satellite images during 18-20 July. Images revealed nothing unusual during 20-22 July.
Cloud cover mostly prevented observations during 22-24 July; a steam plume rose from the crater on 23 July. The Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange.

Cleveland volcano in the Aleutian Islands (Alaska) had an explosive eruption at 14.05 local time on 19 June, the Alaska Volcano Observatory (AVO) reported, who raised the alert status to Orange (3 out of 4). Based on pilots' observations, an ash plume rose to about 35,000 ft (10,6 km). As the eruptions blog writes, a possible explanation could be that the eruption was caused by a collapse of the lava dome, but Cleveland's remote location makes it difficult to confirm this. ...

A pilot report, a web camera image, and infrasound data all indicated that an ash-producing explosion occurred around 1405 on 19 June. The pilot report suggested that the cloud altitude was 10 km (35,000 ft) a.s.l. and the infrasound data indicated that the eruption duration was short. ... [more]

On 4 June a possible small explosion was detected by infrasound. [more]
Tuesday, May 08, 2012
Based on analyses of satellite images, AVO reported on 4 May that the small lava dome recently emplaced in Cleveland's summit crater had been destroyed late in the previous week, but the explosion was too small to be detected by distant infrasound and seismic networks. A small new dome was extruded following the explosion and was the fifth dome to be observed in this eruptive episode which began in July 2011. During 4-5 May two small explosions were detected. ...
