Natural disasters in Indonesia

Indonesia has experienced a series of natural disasters across multiple provinces, primarily involving forest fires, flooding, and landslides. In late October, forest and land fires were reported in Sulawesi, specifically affecting Sinjai, Tojo Una-Una, and Sigi. In Central Sulawesi, a 60 hectare fire on Mount Ranindi was reportedly caused by community activities related to damar tree management. Meanwhile, heavy flooding in West Sumatra damaged critical drinking water infrastructure in Padang, including the Guo Kuranji facility, impacting approximately 10,000 households. By the end of the month, reports indicated continued fire activity in Southeast Sulawesi, Maluku, and South Sulawesi, though no fatalities were reported from these specific incidents. Additionally, extreme weather and heavy rain in Central Java triggered 21 disaster events in the Banyumas Regency, including 14 landslides and five floods. These events caused damage to local infrastructure, such as schools and roads, due to river overflows and breached embankments. In response to weather predictions from the Meteorology, Climatology, and Geophysics Agency (BMKG) regarding the upcoming rainy season, the National Disaster Management Agency (BNPB) issued Circular Letter Number 4 of 2026. Signed by BNPB Head Letjen TNI Kristomei Sianturi, the directive outlines eight strategic preparedness steps for local governments to mitigate hydrometeorological risks, including floods, landslides, and strong winds. The measures include mapping disaster-prone areas, strengthening early warning systems, and ensuring 24-hour emergency response posts. As of November 4, 2026, the BNPB reported that Indonesia has recorded 2,295 natural disasters since the beginning of the year, resulting in 427 deaths, 21 missing persons, and affecting over 6 million people. In the Riau Islands, regional Secretary Misni reported 1,231 disaster cases between January and September, an increase from 948 cases in 2025.
