Rumbling Mount Sinabung on Indonesia's Sumatra island erupted today, sending a column of volcanic materials as high as 5,000 metres into the sky.
There were no fatalities or injuries from the morning eruption, Indonesia's Volcanology and Geological Hazard Mitigation Centre said.
Villagers are advised to stay 5km from the crater's mouth and should be aware of the peril of lava, the agency said.
Some 30,000 people have been forced to leave homes around the mountain in the past few years.
