Powerful bursts of hot ash and gravel erupted from a rumbling volcano in western Indonesia early Monday (local time), sending panicked villagers streaming down the sides of the mountain.
Six new eruptions in the morning sent lava and searing gas tumbling up to 1.5 kilometres down the slopes of Mount Sinabung in North Sumatra province. Volcanic material spewed as high as 2,000 metres into the air a day after authorities had raised the volcano's alert status to the highest level.
About 15,000 people have been evacuated from 17 villages in the danger zone 5 kilometres around the crater, National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho said. The evacuation zone was expanded from 3 kilometres.
Thick, gray ash covered villages, farms and trees as far as 70 kilometres north of Mount Sinabung's crater, hitting the towns of Binjai and Langkat.
"Everything turned hot surrounding us," said Jatah Surbakti, a 45-year-old farmer who fled with his wife and four children to a shelter on trucks provided by the local disaster agency, along with hundreds other villagers.
