The exact moment of the Calbuco Volcano eruption captured by a currently anonymous hiker in Chile. The volcano erupted on April 22, 2015, for the first time in four decades (the last one was in 1972).
The eruption lasted 90 minutes and sent a plume of volcanic ash 10 km into the sky. A flow of lava was reported into Chapo Lake on the same day. The eruption caused airline flight cancellations to Chile as well as Argentina and Uruguay. Authorities evacuated 4000 people from a zone with a 20 km radius from the volcano.
