Authorities are trying to induce rain through cloud seeding. Chemicals such as silver iodide and salt are sprayed into clouds as part of the technique, which can increase rainfall by up to 15 percent.However, Chaniago cautioned that authorities are struggling to find enough rain clouds to target.“That is why we ⁠closely monitor even small changes in the weather. Whenever something is likely to produce rain clouds, we immediately carry [cloud seeding operations] out,” he said.On Tuesday, firefighters were among more than 150 personnel working to extinguish what remained of a blaze at Bromo Tengger Semeru National Park in East Java province. The fire, which has destroyed about 900 hectares (2,200 acres) of land since starting nine days ago, has been mostly brought under control. It now covers about 2 hectares (5 acres).More than a dozen aircraft have been deployed across Indonesia as part of cloud-seeding efforts, along with 43 helicopters assisting firefighters on the ground.More than 107,000 hectares (264,000 acres) of land across the country were affected by blazes from January to June, according to Ministry of Forestry data. That marks an increase of 110 percent compared with the same period in 2023, when El Nino last affected Indonesia.
