Chaitén volcano (Chile), activity update: lava dome collapse (19 Feb 09)

ven., 20 févr. 2009, 12:00
12:00 PM |
Chaitén volcano experienced an increase in activity over the past few weeks. Yesterday, around 11 am local time on 19 Feb., a largere section of the growing lava dome in the crater collapsed, triggering a large pyroclastic flow that came close to the already largely abandoned town of Chaitén. According to press reports, heavy ash falls occurred in the area and the evacuation of the remaining residents of the town is under way. ONEMI reports the eruption of a considerable column of ash.
Similar future events triggering pyroclastic flows, as well as mud flows by remobilization of fresh ash by rains could occur any time and threaten what is left of the town of Chaitén.
