“The second eruption of Calbuco Volcano was recorded, red alert level remains in force,” Chile's National Geology and Mining Service (SERNAGEOMIN) wrote on Twitter on Wednesday.
The first eruption of the volcano was reported by SERNAGEOMIN earlier in the day. The agency's National Volcanic Monitoring Network issued a red alert in response to the eruption.
The volcano sent a plume of ash and smoke several miles high into the sky on Wednesday afternoon. About 4,000 people were evacuated from the area within a 20-kilometer (12-mile) radius of Calbuco crater due to the eruption, according to local media.
Calbuco is located on the territory of Llanquihue National Reserve in the Los Lagos Region. Its last major eruption occurred in 1961. Since 1837, the volcano has had a total of at least 10 eruptions. Calbuco is considered the third most hazardous volcano among Chile's 90 active volcanoes, according to SERNAGEOMIN.
