A Wildfire Near a Famous Volcano in Indonesia Forced a National Park to Close. Here's What's Going On.
Indonesian officials closed all access to Bromo Tengger Semeru National Park in East Java on August 8, 2026, because a wildfire near Mount Bromo was growing fast. The fire started on August 3. By August 9, it had burned about 176 hectares (435 acres) — nearly three times the 60 hectares (150 acres) it covered just two days earlier. Al Jazeera
Park chief Rudijanta Tjahja Nugraha said the park would stay closed until further notice. Reuters reported that the closure would last through August 31, 2026, at 12:01 a.m., unless the fire is under control sooner.
Indonesia's disaster agency, called BNPB, first reported the fire at 5:00 p.m. on Monday, August 3. Hundreds of people — firefighters, police, soldiers, park rangers, and volunteers — were still working to put it out as of August 8 and 9. Helicopters that drop water from above and drones that spray water were also sent to help. Al Jazeera BNPB
Agency spokesperson Abdul Muhari said the main problems are steep ground, strong winds, and heavy forest that makes it hard for firefighters to reach the fire on foot. Mount Bromo is an active volcano inside a caldera, which is a large bowl-shaped crater formed when a volcano collapses. The shape of the land makes it hard to fight the fire from both the ground and the air, because wind can suddenly change direction and push the flames somewhere new.
The broader context here is worrying. Indonesia's weather agency, BMKG, has warned that the country is facing an unusually harsh dry season in 2026. Part of the reason is El Niño, a natural climate pattern that warms Pacific Ocean waters and typically means less rain across Indonesia. When rain stays away, the soil and plant matter on the ground dry out and catch fire easily. That means fires start earlier in the year, burn hotter, and are harder to stop in places that are normally wet.
The numbers tell the story. Fires have already burned about 1,070 square kilometers (415 square miles) of land in Indonesia this year — more than twice what burned in 2023. In 2023, a fire on Mount Bromo itself burned more than 500 hectares (1,235 acres) after a couple lit a flare during a wedding photo shoot. Fires have also returned to the same area around Mount Batok before, according to BNPB, which suggests the land and plants in this crater are especially fire-prone. BNPB
For people who follow how Indonesia handles disasters, the response to this fire stands out for how many agencies are working together. BNPB, park officials, the military, police, and volunteers are all involved. Indonesia built this coordination system after a terrible fire crisis in 2015, when smoke from burning peatlands (soft, wet ground that stores decayed plants) spread across much of Southeast Asia and showed that the country was not ready to respond quickly. The use of water-spraying drones alongside helicopters shows that Indonesia's tools for fighting fires have advanced, though it is unclear whether aircraft alone can make up for how hard it is to reach this fire on foot.
What matters most now is the direction this fire is heading. It grew from about 60 hectares on August 6 to 176 hectares by August 9 — nearly tripling in just three days. With BMKG forecasting a long dry season and El Niño expected to continue, park managers and disaster officials face a key question: can the current fire breaks hold, or will this fire follow the 2023 pattern and grow from a small spark into a major event? The park closure through August 31 gives firefighters time to work. But it will be the fire's behavior, not a date on the calendar, that decides when the park can safely reopen.
