Officials issued a red alert and ordered Bali residents to evacuate after the Mount Agung volcano erupted, blasting ash up to 2.5 miles high.
The steam-based eruptions evolved into magmatic eruptions over the weekend. Indonesia’s Center for Volcanology and Geological Hazard Mitigation raised its alert from orange to red, its highest level, early Monday morning local time, the Associated Press reported. Some 24,000 people were evacuated to temporary shelters over the weekend. Officials targeted 224 locations for evacuation and told everyone within six miles of Mount Agung to leave.
Some fear a major eruption could be imminent. But the head of Bali’s geological agency told AP: “We don’t expect a big eruption, but we have to stay alert and anticipate.”
Indonesia’s volcano monitoring center said Sunday that magma had already reached the volcano’s surface, the Australian Broadcasting Corporation reported. The last eruption of Mount Agung occurred in 1963 and some 1,000 people were killed after little warning an eruption was about to occur.
Flights were suspended at Bali’s airport at Ngurah Rai, stranding close to 7,000 as the volcano erupted three times Saturday and continued on Sunday, Bali’s Regional Disaster Management Agency said. Lombok International Airport on Pulau Lombok also closed, CNN reported.
The Mount Agung ash plume extended up to 4.7 miles high late Saturday, according to tracking by Australia’s Bureau of Meteorology, raining ash down on several communities. Masks were distributed amid evacuations in Bali and Pulau Lombok, CNN reported.
