Alert level raised for Aleutian island volcano

ANCHORAGE, Alaska -- Scientists are raising the alert level for Cleveland Volcano in Alaska's Aleutian chain after satellite data has indicated thermal anomalies.

The Alaska Volcano Observatory on Tuesday raised the level to advisory status.

There is no real-time seismic network at the volcano. Scientists say unrest there is frequent, and short-lived explosions with ash plumes up to 20,000 feet can occur without warning and may not be detected by satellites.

Cleveland is about 940 miles southwest of Anchorage, on a remote and uninhabited island in the Aleutians chain.

The observatory says the last significant eruption of the 5,676-foot volcano began in February 2001 and eventually produced a lava flow that reached the ocean. There were minor eruptions in January, June and October 2009.

Iceland volcano 'pauses'

May 24, 2010 - Latest information received from the Icelandic Meteorological Office indicate that the volcano is no longer emitting any ash but only a steam plume of up to around 10,000 feet. As a result of this lower activity, UK airspace is not expected to be affected.

Volcanologists and Geologists term this quieter spell of volcanic activity as a 'paused' phase. However, it is typical for a volcano like this to have several 'pauses' as part of its overall eruption phase. Only when the volcano has been 'paused' for three months will it then be regarded as being dormant.

Although no ash is being emitted at the moment, while any volcanic activity continues the Met Office will continue to monitor the situation.
