Indonesia's Mount Sinabung erupted on Wednesday, spewing a massive column of smoke and ash into the sky.
The eruption of the volcano in North Sumatra province lasted about 12 minutes, a local geological agency said.
"The volcanic material reached 4,500 metres into the air and lasted for quite a long time," the head of the agency's Sinabung monitoring post, Armen Putra, told AFP.
