Mount Sinabung Eruptions Intensify

An Indonesian volcano has spewed ash thousands of metres into the air in its most violent eruption since rumbling back to life earlier this week for the first time in 400 years.

Thousands of people have fled their homes since the 2,460-metre Sinabung in northern Sumatra started to erupt on Sunday after centuries of inactivity.

Government vulcanologist Agus Budianto said the eruption lasted for 13 minutes, sending a column of ash as high as 3,000 metres into the air.

“We recorded continuous tremors since 7:00pm Thursday (local time) that indicated an intense magma movement inside the volcano,” he said.

Police have evacuated people from the danger zone in a six-kilometre radius from the volcano peak.

“We’re afraid that some locals had returned back to their village from emergency shelters,” he said.

Mr Budianto said the eruption was felt about eight kilometres away.

Indonesia sits on the Pacific ring of fire, where the meeting of continental plates causes high volcanic and seismic activity. It has more active volcanoes than any other country.
