Indonesia’s Mount Semeru spewed more ash on Monday, forcing rescuers to suspend the search for survivors as aerial images showed the extent of the devastation unleashed by the volcano’s deadly weekend eruption.
The biggest mountain on the island of Java thundered to life Saturday, ejecting a mushroom of volcanic ash high into the sky and raining hot mud as thousands of panicked people fled their homes. At least 14 were killed.
Aerial photos showed entire streets filled with grey volcanic ash and mud, which had swallowed many homes and vehicles, including whole trucks.
Rescue operations were suspended because of fresh volcanic activity on Monday.
“All evacuation teams have been pulled out… temporarily because there was a small fresh eruption and it could endanger the evacuation teams,” said rescue worker Rizal Purnama.
“The search will continue today once the situation is a bit safer.”
Indonesia’s national disaster agency said 27 people were still missing.
Dangerous thick plumes of smoke continued to emerge from areas blanketed by the volcanic ash, while rescuers in hard hats tried to dig through the mud to find survivors — and recover bodies.
Their task was made more difficult as the volcanic debris started to harden.
“It’s very difficult… with simple tools,” Rizal Purnama said. “It is very likely bodies that have not been found are buried under the hot mudflow.”
Other rescuers helped desperate villagers salvage their belongings from wrecked homes. Some locals lifted mattresses and furniture on their shoulders while others carried goats in their arms.
Officials have advised locals not to travel within 5 kilometres of Semeru’s crater, as the nearby air is highly polluted and could affect vulnerable groups.
Ash from Semeru travelled up to 4km away after Saturday’s eruption, Indonesia’s geological agency reported.
A sand mine company’s office in Kampung Renteng village was buried, trapping 15 people, according to foreman Hasim, 65, who like many Indonesians goes by one name.
“There’s no news from them. Only one operator was rescued; he’s now at the hospital with burns,” he told the AFP news wire.
Hasim said he ran home after the eruption.
“It was pitch dark,” he added. “It was only 3pm but it looked like night.”
Rescue officials said some people were buried inside their vehicles, with no time to escape.
Those who managed to find shelter recounted the horror after the eruption.
Suwarti Ningsi and her daughter were trapped for five hours at home after the eruption.
“I couldn’t see anything, it was just like at night. Everybody was panicking,” the 42-year-old said.
“I could only pray … for me and my daughter to be saved.”
The ash and mud also polluted the waterways around Mt Semeru, turning them into streams of dark grey sludge.
Rain is forecast for the area, which could further hinder rescue work.
There is also a risk of the rain causing ash sediment to form a new river of hot lava, the country’s top volcanologist Surono told a local TV station.
Mt Semeru’s last major eruption was in December 2020, which also wrecked villages and forced thousands to flee.
Indonesia sits on the Pacific Ring of Fire, where the meeting of continental plates causes high volcanic and seismic activity, and the country has nearly 130 active volcanoes.
In late 2018, an eruption in the strait between Java and Sumatra islands caused an underwater landslide and tsunami that killed more than 400 people.
