In June 2011, the Puyehue Volcano, a volcano in the Puyehue-Cordon Caulle chain of south-central Chile erupted after lying dormant for more than 50 years.
The plume of ash and gases reached Lake Nahuel Huapi in Argentina and covered it with ash. Images are incredible!
During the eruption, several thousand residents had been evacuated after the volcano ejected ash more than 6 miles (10 km) into the sky.
The explosion occurred after a gigantic swarm of earthgquakes – at one point, the tremors reached an average of 230 per hour- below the volcanic peak.
Below the most spectacular photographs of the eruption:
