A state of emergency has been declared in southern Chile, after the region’s dormant Calbuco volcano erupted yesterday. No casualties have been reported. The first eruption, at 6 p.m. local time, threw an enormous column of ash and smoke into the air. So far, 5,000 people have been evacuated from the area, and flights nearly 400 miles away have been grounded. The volcano had been dormant for more than 40 years before erupting twice on Wednesday. The region is fairly sparsely populated, and there's no record of deaths or missing people as a result of the explosion. This is the second volcano to erupt in just two months in Chile, which is situated on the Ring of Fire circle of Pacific volcanos. Calbuco, which last erupted in 1972, is considered one of the top three most dangerous volcanos in Chile. The stunning video below shows the eruption blasting into a sunset-painted sky. Nature, man.
