About 14,000 people were forced the evacuate when the volcano showed signs of activity in September. Sinabung is one of nearly 130 active volcanoes in the world's fourth-most populated country, which straddles the "Pacific Ring of Fire".
On November 11, 2013, a pyroclastic flow, a fast-moving avalanche of ash, lava fragments and air, was seen racing down the peak. Since then, the volcano has blasted out one to two ash explosions every day.
