Indonesia’s heavy rainfall led to the collapse of the Semeru’s lava dome hospitalizing 56 people, mainly with burns, and killing at least 30 people, the youngest being a 13-year-old boy that rescuers had to dig out of the rubble with their bare hands.

Currently there are still 27 unaccounted people, who rescuers have been searching for through the debris of the eruption. The dome that was initially holding the lava inside that kept it from exploding was partially broken after “a heavy spell of rain that day,” says the country’s geological chief, Eko Budi Lelono, from the Ministry of Energy and Mineral Resources.

According to scientists with connections to CCN, concerns are rising around the speculation that the immense weather may cause more frequent eruptions. Lava dome collapses can have much stronger consequences and can cause more destruction. This eruption specifically shot ash up to 15 kilometers in the air when regularly it’s just hundreds of meters. The pyroclastic clouds also reached more than 12 kilometers on land, which is much further than the usual 5 kilometers. More than 8000 people live within 10 kilometers of Semeru. Almost 3000 houses and 38 schools were in the line of fire with drastic damage done to them.
