A volcano in Chile that had been inactive for 50-plus years suddenly erupted twice in the space of hours with tremendous force, blasting huge clouds of ash into the air and forcing the evacuation of some 5,000 people.

There were no immediate reports of injuries after the eruptions from the Calbuco volcano in southern Chile Wednesday evening and then again seven hours later, early Thursday.

A state of emergency was declared after the first eruption, and air traffic was disrupted.
