YOGYAKARTA, INDONESIA (AP) — Indonesia’s most active volcano erupted yesterday with a river of lava and searing gas clouds flowing 1,600 metres down its slopes.
It was Mount Merapi’s biggest lava flow since authorities raised its danger level in November, said head of Yogyakarta’s Volcanology and Geological Hazard Mitigation Center Hanik Humaida.
After morning rain, ashfall turned into muck in several villages, where the sound of eruption could be heard 30 kilometres away. Police and rescue services told miners to cease work along rivers but no one was evacuated.
Authorities in November had evacuated nearly 2,000 people living on the mountain in Magelang and Sleman districts on Java Island but most have since returned.
The alert was being maintained at the second-highest level and authorities told people to stay out of the existing five-kilometre danger zone around the crater as the local administrations in Central Java and Yogyakarta provinces closely monitor the situation.
The 2,968-metre volcano is on the densely populated island of Java and near the ancient city of Yogyakarta. It is the most active of dozens of Indonesian volcanoes and has repeatedly erupted with lava and gas clouds recently.
Merapi’s last major eruption in 2010 killed 347 people.
Indonesia, an archipelago of 270 million people, is prone to earthquakes and volcanic activity because it sits along the Pacific “Ring of Fire,” a horseshoe-shaped series of seismic fault lines around the ocean.
