Ash clouds and flows of lava coming from Indonesia's Mount Soputan.
A volcano on the central Indonesian island of Sulawesi erupted with plumes of white smoke and sandy volcanic debris that soared nearly 5,000 feet (1,525 metres) into the sky on Thursday.
Residents living as far as 12 miles (19 km) from the crater reported feeling the heat of erupting Mount Soputan.
While there were no reports of injuries, many wore face masks to protect themselves against the heavy smoke and dust emitted by the volcano.
People living around Soputan have been on alert since August, when the mountain produced a weaker eruption. Many had been evacuated just prior to this week’s blast.
Indonesia has more active volcanoes than any other nation in the world due to its location on the Pacific "Ring of Fire" — a series of fault lines that stretch from the Americas to Asia.
