A Chilean volcano in the Puyehue-Cordon Caulle has erupted for the first time in 50 years. The volcanic chain is about 575 miles south of the capital, Santiago but because of the ash cloud and weather conditions, it's not yet clear which particular volcano of the four is erupting.
The ash cloud has been thrown 6 miles (10 kilometres) into to the sky with winds fanning the cloud towards Argentina as the Chaiten eruption did 3 years ago.
Authorities had been expecting the eruption after repeated earthquakes were reported in the area and the volcanic range then entered an explosive eruptive process. The air is full of the smell of sulphur and seismic activity is continuous.
Chile's chain of about 2,000 volcanoes is the world's second largest after Indonesia. Some 50 to 60 are on record as having erupted, and 500 are potentially active.
