Massive Wildfire Threatens Indonesia’s Iconic Mount Bromo

A wildfire ignited on August 3, 2026, inside Bromo Tengger Semeru National Park in East Java, along a shortcut used by local residents. By August 8 the park was closed and firefighting teams deployed water-bombing helicopters, drones and fire trucks. Initial reports placed the burned area at roughly 60 ha, but the blaze expanded to 550 ha by the following Sunday. On August 10 officials said the original blaze had been extinguished, yet new hotspots of about 20 ha appeared near the volcano’s caldera. Active hot spots remained at Puncak 30, a popular viewpoint, and Dengklek, where a monitoring post sits. Ground crews continued battling the flames, expecting the last hotspots to be out by week’s end.

Mount Bromo Wildfire Spreads in Indonesia – GKToday

Indonesia’s 2026 dry season has been unusually long and severe, intensified by a strong El Niño event. The meteorological agency (BMKG) warned that July’s average temperature of 27 °C exceeded the long-term average of 26.2 °C, the highest July reading since 1991. El Niño creates dry vegetation, strong winds and low humidity that allow forest and peatland fires to spread. Dry peat can smolder underground for weeks, producing haze that drifts across borders.

• Fires have scorched more than 107,000 ha nationwide from January to June, a 110 % increase over the same period in 2023.

• Peatland burning accounts for nearly 48,900 ha across six provinces.

BNPB chief Suharyanto highlighted the importance of aerial support in peatland zones, noting that “aerial operations are supporting ground operations which are especially critical in peatland areas.” Mayor Edi Rusdi Kamtono of Pontianak ordered schools to shift to remote learning while air quality remained unhealthy, describing the haze as “blanketing the city.” Malaysia’s Sarawak state recorded “unhealthy” air-quality indices, prompting the suspension of outdoor school activities.

The exact extent of the Bromo wildfire remains uncertain. Sources report burned areas ranging from 176 ha to 900 ha, and hotspot counts differ between “two remaining locations” and “four active zones” within the park. No casualty figures have been confirmed, and the cause of the fire is still under investigation, though human negligence along a visitor shortcut is suspected. Data on the effectiveness of cloud-seeding operations is limited, with officials acknowledging a shortage of suitable clouds.
