Calbuco volcano erupts in southern Chile for first time since 1972; nearby town evacuated

Chile's Calbuco volcano has erupted for the first time in more than 42 years, and Chilean authorities have ordered the evacuation of the few thousand people living in a town a few miles away.

The National Mining and Geology Service has issued a high alert, barring access to the mountainous area around the volcano in southern Chile. The area is sparsely populated, with only a few small communities. The town of Ensenada is being evacuated as a precaution.

The volcano's last eruption was in 1972 and it is considered one of the top three most potentially dangerous among Chile's 90 active volcanos.
