The Villarrica volcano, in southern Chile, started erupting overnight, sending a column of fire and rocks into the dark sky.
The eruption started at about 3 a.m. local time (5 a.m. GMT, 12 a.m. EST).
Local news website Emol.com reports that the eruption was highly expected, after weeks of increasing activity. Local authorities called for a red alert in all the area surrounding the volcano and nearby communities were evacuated.
The volcano has already experienced two major eruptions, in 1964 and 1971.
Here’s a dramatic GIF of the eruption.
The volcano is about 2,860 metres (9,380 ft) high.
Villarrica is about 750 km south of Chile’s capital Santiago.
