Earth Day Volcano Rains Fire and Lightning on Chile, Prompts Evacuation

Chileans are expecting heavy ash-fall for the remainder of the week, with officials even in neighboring Argentina asking that residents in the city of Bariloche - about 60 miles from Calbuco - to stay indoors, according to BBC News.

The 6,500-foot Calbuco last erupted in 1972 and is considered one of Chile's top three most potentially dangerous volcanoes. The country boasts 90 active volcanoes in all.
