The Calbuco volcano in Chile erupted for the first time in 42 years on Wednesday, CNN reports.
Chile's Calbuco volcano erupted twice in 24 hours, the country's National Geology and Mining Service said early Thursday.
The agency said it was evaluating the spectacular nighttime eruption, but indicated it was "stronger than the first one."
Authorities issued a red alert for the towns of Puerto Montt and Puerto Varas in southern Chile. Both are popular tourist destinations.
A 12-mile (20 kilometer) exclusion zone was established around the crater. Military and police forces were assisting with the evacuations of about 1,500, according to the Ministry of Interior and Public Safety.
