The forest and land fire in the Mount Semeru area has been declared extinguished after joint teams found no remaining hotspots. Lumajang disaster agency chief executive Isnugroho said the response formally ended on September 5, 2026.

The fire burned 3,072 hectares by September 1, according to data from Bromo Tengger Semeru National Park. Officials were still calculating the area affected in the Krepelan block near Ranupani, so the final figure for the full impact remained uncertain.

Ranu Kumbolo and its surrounding area suffered the largest burned area, covering about 1,887 hectares. Other affected zones included Bantengan, Watangan, Jantur and B29, with 881.78 hectares, as well as Dingklik, Pacis Bincil, Kedaluh and Penanjakan, with about 211.24 hectares.

We coordinated with the TNBTS Regional PTN Section III in Ranupani, Lumajang, because as of September 5, 2026, the activities were declared complete as there were no more hotspots, and patrols by TNBTS would follow.
