Puyehue volcano (Chile), activity update: continuous ash eruptions reaching 10-12 km
Monday Jun 06, 2011 19:49 PM |
The spectacular explosive eruption at Puyehue volcano continues, although its intensity seems to have decreased slightly. It is producing a sustained column of ash that reaches 10-12 km altitude and is currently drifting NE. Significant ash fall is occurring SE, E and NE of the volcano including the province of Río Negro, Argentina, with the popular resort town of Bariloche, where heavy ash fall is reported and causing problems to daily life and infrastructure.
Wide-spread flight disruptions have been caused in the region, and both Argentinian and Chilean airlines have temporarily cancelled many domestic flights. Airports affected include Baricloche, Neuquen, Esquel, Chapelco, Trelew, Viedma, Rio Gallegos, El Calafate, Ushuaia, Rio Grande and Comodoro Rivadavia.
It appears from preliminary analysis of infrared satellite data measuring hotspots that the vent of the new eruption is just NW of the 1960 vents, ie. from the Caulle fissure system: twitpic.com/57qpdb
Near the volcano, a wide-spread evacuation zone is in place including the towns of Lago Ranco, Futrono, Río Bueno and Lago Ranco in the Los Ríos region and Puyehuein the Los Lagos region. This area is at significant risk of mud flows (lahars).
