Cleveland volcano (Aleutian Islands, Alaska): alert level raised
Sun, 21 Mar 2021, 07:28 | BY: T
The alert level of the volcano was raised to yellow again, after the Alaska Volcano Observatory (AVO) detected increased volcanic gas emissions and elevated surface temperatures via satellite data starting from 17 Mar. "In addition, a local earthquake occurred on 10 Mar and was large enough to be measured on seismometers 100 km away on Umnak Island. These data indicate a potential for increased eruptive activity at Cleveland." (AVO)
The volcano last erupted last June, when an explosion or series of explosions on 2 June produced a small ash cloud to 22,000 ft (7 km) altitude. Explosions from Cleveland typically produce relatively small volcanic ash clouds that dissipate within hours; however, more significant ash emissions are possible.
