Sinabung, a volcano that rises to 2,460 meters in the north of the island of Sumatra, lay dormant for several centuries before waking up in 2010 in an eruption that killed two people.
The volcano has experienced two other fatal eruptions, one in 2014 killing at least 16 people and the other in 2016 with seven other victims.
There are 130 active volcanoes in Indonesia, an archipelago of more than 17,000 islands and islets.
The country is located on the Pacific Ring of Fire, an area of strong seismic activity and volcanic eruptions, where three large tectonic plates converge (Indo-Pacific, Australian, Eurasian).
The Merapi on the island of Java has also shown strong activity in recent weeks.
It again emitted incandescent lava flows on Monday.
