Jakarta: A volcano in western Indonesian has unleashed hot clouds of ash, killing at least six people and injuring several others.
Mount Sinabung in North Sumatra province blasted volcanic ash as high as 3 kilometres into the sky on Saturday, said National Disaster Management Agency spokesman Sutopo Purwo Nugroho.
He said ash tumbled down the slopes as far as 4.5 kilometres westward into a river.
The 2600-metre-high mountain in Karo District had been dormant for four centuries before springing to life in August 2010, killing two people and forcing 30,000 to flee.
An eruption in February 2014 killed 16 people.
All the victims of Saturday's eruption were working on their farms in the village of Gamber in Simpang Empat subdistrict, about 4 kilometres away from the slope, or within the danger area.
"A search-and-rescue team continues to scour houses and farmlands in the area to look for more victims. It is unclear how many people were in the red zone when the hot clouds unleashed," The spokesman said.
The disaster management agency has declared areas within a radius of seven kilometres closed during the emergency.
Mount Sinabung is among more than 120 active volcanoes in Indonesia, which is prone to seismic upheaval due to its location on the Pacific Ring of Fire, an arc of volcanoes and fault lines encircling the Pacific Basin.
