It is now among more than 120 active volcanoes in Indonesia, which is prone to seismic upheaval due to its location on the "Pacific Ring of Fire".
Mount Sinabung, among about 130 active volcanoes in Indonesia, has sporadically erupted since 2010 after being dormant for 400 years.
More than 22,000 people were evacuated from the area after eruptions earlier this year that killed at least 16 people. Most have returned home, but about 4,700 remain in evacuation centers.
