Mount Sinabung erupted on Monday, sending a dense plume of volcanic ash around 3.5km into the sky and prompting Indonesian authorities to warn residents and tourists to stay away.
The volcano, located in Karo regency in North Sumatra, began erupting at 10.17am local time, Lana Saria, head of the national geological agency, said. “The ash column appeared black and thick, tilting towards the east and southeast,” she said.
