YOGYAKARTA, Indonesia—Indonesia’s most active volcano erupted Wednesday with a river of lava and searing gas clouds flowing 3,000 meters (nearly 10,000 feet) down its slopes. No casualties were reported.
The sounds of the eruption could be heard 30 kilometers (18 miles) away, officials said. It was Mount Merapi’s biggest lava flow since authorities raised its danger level in November, said Hanik Humaida, the head of Yogyakarta’s Volcanology and Geological Hazard Mitigation Center.
