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.
