Volcanic smoke rises from Mount Semeru’s crater as seen from Supiturang Village, Lumajang, East Java, Wednesday (Feb. 25, 2026). According to the Center for Volcanology and Geological Hazard Mitigation (PVMBG), the eruption produces an ash column 400-600 meters above the summit, and residents are urged to remain alert to potential lava flow flooding due to ongoing heavy rainfall.
