Lumajang: The death toll from a sudden, massive eruption of Indonesia’s Mount Semeru has risen to 13, forcing thousands to flee from its path of destruction and forcing hundreds of families into makeshift shelters, disaster officials said on Sunday, as rescuers searched villages blanketed in molten ash for survivors.
The eruption of Java’s biggest mountain caught locals by surprise on Saturday, leaving at least 11 villages of Lumajang district in East Java province coated in volcanic ash, submerging houses and vehicles, smothering livestock and leaving at least 900 evacuees seeking shelter in mosques, schools and village halls.
Dramatic footage showed Semeru pumping a mushroom of ash into the sky, looming ominously over screaming residents of a nearby village as they fled.
“The death toll is now 13 people. Rescuers found more bodies,” national disaster mitigation agency (BNPB) spokesman Abdul Muhari told media, without specifying the cause of death.
Two of the victims have been identified, he said in a later statement.
At least 57 people were injured in the eruption, of whom 41 suffered burns and were hospitalised, the BNPB said in a press release.
As many as 10 trapped people were rescued from the surrounding areas in Lumajang, Muhari said, as villagers and rescuers worked through the night to find anyone trapped or retrieve bodies.
Local broadcaster reported those rescued were local workers at a sand mining site.
Evacuations were temporarily suspended on Sunday due to hot ash clouds, Indonesia’s Metro TV reported.
There is also a risk of heavy rain causing ash sediment to form a new river of hot lava, the country’s top volcanologist Surono told the station.
Lava mixed with debris and heavy rain had already destroyed at least one bridge in Lumajang, preventing rescuers from immediately accessing the area.
But emergency service footage on Sunday showed a desolate scene in one village swallowed by the eruption, with roofs of houses protruding from the coat of mud that destroyed them.
Rescue workers dressed in bright orange uniforms worked against a dark-grey backdrop, a scene of ruin surrounded by buckled buildings and fallen trees.
In others, villagers tried to salvage their belongings from wrecked homes. Some held mattresses and furniture on their shoulders while others carried goats alive in their arms.
The rescue teams were using heavy loaders to remove debris and clear roads, Muhari said.
Locals have been advised to not travel within five kilometres (3.1 miles) of Semeru’s crater, and the air around it is highly polluted and could affect vulnerable groups, he added.
“For now, we urge people not to stay because the volcanic ash is still relatively hot,” Indra Wibowo, head of the local disaster agency, told media.
Officials have sent aid to shelters, including food, tarpaulins, face masks, and body bags.
Ash spewed by the volcano travelled up to four kilometres from the volcano, Indonesia’s geological agency said, reaching as far as the Indian Ocean in the southern part of Java island.
But Australia’s Volcanic Ash Advisory Centre, which provides advice to the aviation industry, said the ash had now dissipated around Semeru on Sunday, according to satellite imagery.
The volcano’s alert status has remained at its second-highest level since its previous major eruption in December 2020, which also forced thousands to flee and left villages covered.
Indonesia sits on the Pacific Ring of Fire, where the meeting of continental plates causes high volcanic and seismic activity.
The Southeast Asian archipelago nation has nearly 130 active volcanoes.
In late 2018, a volcano in the strait between Java and Sumatra islands erupted, causing an underwater landslide and tsunami which killed more than 400 people.
