Chilean volcano continues to smoke

Chilean volcano continues to smoke Danger Zone

Volcano Puyehue-Cordon in Chile does not cease to produce a large amount of ash more than 6 months after the eruption, which occurred June 4, 2011. According to the Smithsonian Global Volcanism Program, in late November the crater were observed plumes of smoke high 2.3-2.5 km, making it difficult for the railroad led to the delay and cancellation of flights from Uruguay.

In the picture of the traveler Terra from November 25, 2011, is seen as a cloud drifted hundreds of kilometers in the direction of Argentina and the Atlantic Ocean. Image is a combination of three images taken at three positions satellite for 1 hour and 40 minutes (from 3:10 to 14:50).

The photo shows how the ash cloud rising in the west of the Andes and extends to the east. A layer of ash is so dense that it is not visible because of Argentina and strip the ocean, but clearly visible phytoplankton. Increase in the number of small aquatic organisms, probably due to the favorable conditions for them: the right temperature of water, light and certain nutrients, such as iron, a lot of which is contained in the ash.

Volcanoes Observatory of the Southern Andes (OVDAS) and the National Geological Service of Geology and Mining (SERNAGEOMIN) report that in the last day the degree of activity of the volcano is at level "red alert." Eruptive processes of low-intensity, one can expect the risk in large emissions of ash, making it difficult to travel by air. Analysis of seismic activity has shown that such a behavior of the Puyehue-Cordon continue on. Ability to remain low due to the eruption of lava and changes in the dynamics of the volcano.
