Chaitén Volcano Eruption, Chile - John Seach

An overflight of Chaitén volcano this morning showed a dense column of white to grey emissions reaching a height of 20 km, and drifting SSE with the prevailing winds. The geoloogical record of Chaitén volcano shows a history of pyroclastic flows and ashfall. This explosive character of the volcano suggests that ashfall may reach a considerable distance from the volcano. Pyroclastic flows are possible, and are associated with dome collapse. The volcano is not covered with ice and there is no immediate danger from lahars.
