A powerful burst of hot ash and gravel has erupted from a rumbling volcano in western Indonesia, sending panicking villagers fleeing down the mountain.
Authorities raised the alert status to the highest level after a series of eruptions from Mount Sinabung yesterday. Six more eruptions early today sent volcanic debris as high as 6,500ft (2,000m) into the air.
National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho said about 15,000 people have been evacuated from 17 villages in the danger zone, a three-mile (5km) area around the crater.
Transportation Ministry spokesman Bambang Ervan said airlines had been notified to avoid routes near the mountain in North Sumatra province.
