The Sinabung volcano, one of the most active on the Indonesian island of Sumatra, spewed smoke and ash this Monday, at a height of five kilometers, with no injuries reported, the volcanology agency said.
A thick layer of ash covered several villages within a radius of 20 kilometers around the crater, an official at the Sinabung volcano observation post told the Associated Press (AP) news agency.
Residents were advised to stay five kilometers from the crater. About 30,000 people have been forced to leave their homes in recent years due to the activity of the Sinabung volcano.
The volcano, one of three that in Indonesia frequently erupts, has been dormant for four centuries, but went live in 2010, causing two deaths.
Four years later, in 2014, 16 people died in a volcanic eruption, and seven in 2016. Indonesia is located in the so-called Pacific Ring of Fire, an area of great seismic and volcanic activity, with more than 400 volcanoes, of which at least at least 129 remain active and 65 are classified as dangerous, including Sinabung.
