The eruption of Cordon Caulle began on June 4, 2011, located in the Region of Los Rios in Chile. For about 12 months, people and animals became accustomed to living with the daily fall of ash, which also caused problems in the air traffic in South America. The explosions and lightning during first days of the eruption could be seen from hundreds of miles around. This photograph was taken on the second night of eruption from the town of Lago Ranco.
