Mount Bromo Wildfire Spreads in Indonesia

A wildfire broke out on 3 August 2026 inside Bromo Tengger Semeru National Park in East Java, Indonesia, and affected the Gunung Bromo Watu Gede and Jantur areas. The fire later spread near the volcano’s caldera, and emergency agencies deployed helicopters, fire trucks, and drones for containment.
