Chaitén: A New Phase of Activity?
On June 29, 2009, after a magnitude 5.3 quake struck off coast of Isen, Chile, at a depth of 10km, the Moderators forecast:
FEWW believes that the quake could be followed by more shocks, a number of which could be larger in magnitude, along the Chile Ridge, near the coast of Chile and about the subducting Nazca Plate. Additional seismic activity in the region could result in a new, more intense phase of activity in Chaitén, or prime other regional volcanoes for eruption.
Well, Chaitén is still awake, doing what volcanoes do best: Spewing ash, steam, sulfur…
Ash and Steam Plume from Chaitén
The Advanced Land Imager (ALI) aboard the NASA/USGS Earth Observing-1 (EO-1) satellite acquired this natural color image of Chaitén on September 27, 2009, at roughly 10:30 am local time. According to a report, there was an ash plume extending 56 km (35 miles) northwest of the summit at the time the image was taken.
