Small explosive eruption reported at Alaska’s Mt. Cleveland volcano

November 27, 2013 ALASKA Mt. Cleveland, an active volcano in the Aleutian Islands underwent a brief, small explosion Tuesday evening. The explosion, which took place at about 7:31 p.m. Alaska time, was detected by remote seismic devices and other monitoring equipment, according to the Alaska Volcano Observatory. “It is possible that a small ash cloud was generated but if so, it was too small to be observed in satellite data,” reported AVO. Cleveland, a stratovolcano (that’s the steeply-sided, symmetrical cone-shaped variety for lay folks) that comprises the western half of Chuginadak Island, is one of the Aleutians most active volcanoes. The AVO currently lists Cleveland at a yellow alert level; it has been at that level since being downgraded from orange following its eruption in May. That eruption threatened, but eventually failed, to disrupt the significant air traffic that travels in nearby corridors. After Tuesday’s explosion, the peak exhibited no further signs of what the AVO terms “eruptive activity.” –Alaska Dispatch
