Chile: Volcanic Activity Continues At Puyehue Corón-Caulle


By Mark Dunphy – “NASA satellite imagery shows that the eruption of Puyehue Corón-Caulle Volcano is continuing after more than 4 months of activity.

A conspicuous plume of volcanic gases and fine ash rose above the volcano on Sunday (October 9, 2011), and blew southeast over Argentina.

In the top natural-color satellite image the mountainous landscape is covered with gray ash, largely snow-free for the first time in several months. To the north and southwest of the active vent is a lava flow, its textured appearance suggestive of thick lava. Immediately west of the vent the flow appears fresh—its dark surface not yet covered by lighter ash.

In a false-color image made from shortwave infrared, near infrared, and visible light data (above, lower), the vent and nearby lava flow are bright orange. This is a sign of intense heat, and likely indicates ongoing emissions of lava. These images were acquired by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite.” Source.
