Indonesia’s Mount Sinabung, which has been active since 2010, spewed volcanic ash as high as 5,000 metres into the air, as it erupted on Monday.

The 2,460 metre-high volcano sent a hot cloud of ash in the southern and southeastern direction, according to a volcanologist report. But the eruption did not

disrupt flight paths at the nearest city of Medan and Indonesia’s National Disaster Mitigation Agency said no casualties were reported.

This was the biggest ever eruption of the volcano in 2018. Before an eruption in August 2010, Mount Sinabung had been inactive for four centuries.

Indonesia straddles the so-called “pacific ring of fire” and is prone to seismic activities and occasional eruptions.
