Chile Volcano Puyehue



   
June 6, 2011 -- A thick plume of ash from the erupting Puyehue volcano in the Andes shifted direction into Chile on Sunday after spewing volcanic dust over parts of Argentina and forcing a major border crossing point to close due to low visibility. 

North-westerly winds pushed the giant column of ash from the Chilean volcano, located 870 kilometers (540 miles) south of the capital Santiago near the border with Argentina, into Chile's Lago Ranco area.  

The eruption forced some 3,500 people to be evacuated from 22 rural Chilean communities.

"This change means that we will have ash falling in the area, with damage to the population and a threat to small farmers," Lago Ranco Mayor Santiago Rosas told AFP. 

Puyehue, one of several domes along the Cordón Caulle geothermal rift zone, rumbled to life on Saturday. The last minor eruption from this chain of volcanoes located in the Andes 2,240 meters (7,350 feet) above sea level was in 1990. The last major eruptive episode occurred on May 24, 1960, following the magnitude 9.5 earthquake that struck Chile on May 22.  


    "There are some people, especially heads of family, that have decided to stay home and take a risk. The government, for the time being, will not interfere in that individual decision," said the regional governor in Chile, Juan Andres Varas.

Ash fell on the upscale Argentine resort town of Villa La Angostura and forced the nearby Argentine resort town of Bariloche, population 50,000, to declare a state of emergency on Saturday and close down its airport. 

Bariloche, located about 100 kilometers (62 miles) east of the volcano, was covered in a sooty blanket of several centimeters (inches) thick and remains under a state of emergency.

The picturesque town, as well as others in the vicinity affected by the ash, welcomes thousands of foreign tourists each year to its lakes and mountain scenery, as well as ski slopes in the winter months. 


Chile has some 3,000 volcanoes, of which some 500 are geologically active and 60 have erupted in the past half century.


In 2008 the eruption of the Chaiten volcano, also in southern Chile, spread a thick cloud of ash across a large swath of South America, grounding flights across the region. Ash from that eruption drifted east as far as the Argentine capital of Buenos Aires.
