PROBOLINGGO — Mount Bromo in East Java erupted on Thursday, 5 November 2026, at 17:11 Western Indonesia Time. According to the Geological Agency of the Energy and Mineral Resources Ministry, the ash column rose about 500 meters above the summit, or 2,829 meters above sea level. The grey ash, ranging from thin to thick, drifted west.
The eruption was recorded on seismographs with a maximum amplitude of 23 mm and a duration of about 46 seconds. “Mount Bromo is currently at Level II (Alert),” the Geological Agency said, as quoted by CNBC Indonesia.
Geological Agency Recommendations
- Residents around Mount Bromo and visitors, tourists and climbers must not enter a 1 km radius of the active crater.
- Residents, vendors, tourists, climbers and tourism operators should watch for phreatic eruptions, which can occur suddenly without clear prior volcanic signs.
Tourism Still Open, Supervision Tightened
The Bromo Tengger Semeru National Park Authority (BB TNBTS) has tightened supervision and barred tourists from approaching the crater. Park head Rudijanta Tjahja Nugraha said the 1 km safety limit from the crater rim is physically marked with posts and has been guarded by joint police and military personnel since Friday morning, 6 November.
The tourist area has not been fully closed because Bromo’s status has not been raised. But the park says it is ready to close the area if conditions worsen. “If the status changes quickly, we will immediately respond with a closure. That’s certain,” Rudijanta said, as quoted by CNN Indonesia. He urged visitors to follow the rules for everyone’s safety.
Evacuation Routes Mapped
Meanwhile, the Probolinggo Regional Disaster Management Agency (BPBD), together with the military and police, re-mapped evacuation routes and shelter posts in case of further eruptions. “Today, together with the military and police, we re-mapped evacuation routes and shelter posts as a mitigation step should Mount Bromo erupt again,” said BPBD Probolinggo executive head Oemar Sjarif, as quoted by JPNN Jatim.
Oemar said Bromo’s volcanic activity was stable as of Friday morning. BPBD continues to coordinate with the Bromo Volcano Observation Post and the national park authority. Residents of villages around Bromo are urged to stay calm, follow official information and respect the designated safety limits.
