Chile's Full-Time Volcano August 26, 2011
Puyehue Cordón Caulle
On the morning of August 14, Puyehue Cordón Caulle emitted an ash plume that streamed east-northeast over Argentina, where it dispersed.
Chile’s Puyehue Cordón Caulle Volcanic Complex has now been erupting for nearly two and a half months, but with far less force than during its initial violent phase.

Several powerful blasts during June blanketed a broad swath of neighboring Argentina with a thick coat of ash.

Massive plumes of ash transported by jet stream winds grounded aircraft half a world away in New Zealand and Australia.

But weaker blasts now limit the range of smaller ash clouds to the Andes and Argentina’s Patagonia region.

NASA says that emissions of fine ash and volcanic gases are accompanied by volcanic tremors — “continuous, rhythmic ground shaking.”
