Chaitén Volcano, Chile - John Seach

On Monday 12th May, emissions from Chaitén volcano in Chile reached an altitude of 8 km. Pyroclastic flows have burned several hectares of forest. A vertical dome is located in a 1 km wide crater. The Chaitén River has overflowed due to silting up from ash and pumice, and lahars extended 200 m either side of the river. About 40 buildings, and many vehicles, were buried by the lahars. Lahars remain an ongoing hazard at the volcano. Earthquakes greater than magnitude 3, and earthquake swarms lasting 5 minutes have been recorded at the volcano.
