Kanlaon Volcano Eruption Triggers Widespread Ashfall and Sulfuric Smell Across Negros
A total of twelve local government units in the Negros Island Region have reported significant ashfall and a distinct sulfuric odor following a moderately explosive eruption of Kanlaon Volcano on Thursday evening, February 26, 2026. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) confirmed that the eruption occurred at 7:04 PM and lasted for approximately two minutes, marking a notable volcanic event in the region.
Eruption Details and Immediate Impacts
According to PHIVOLCS, the explosive activity generated a substantial plume of smoke and ash that soared to an impressive height of 2,500 meters above the crater, primarily drifting toward the southwest. This ashfall has affected multiple communities, leading to disruptions and health concerns due to the pervasive sulfuric smell accompanying the volcanic debris.
Additional hazards included the observation of incandescent rock fragments raining down around the crater area, along with pyroclastic density currents (PDCs)—fast-moving flows of hot gas and rock—that cascaded down the eastern and southeastern slopes. These dangerous currents extended up to two kilometers from the summit, posing risks to nearby areas and highlighting the volcano's dynamic and potentially destructive nature.
Regional Response and Safety Measures
Local authorities in the affected LGUs are actively monitoring the situation and implementing safety protocols to protect residents from the ashfall and potential further volcanic activity. The eruption serves as a stark reminder of the volcanic risks inherent in the Philippines, with PHIVOLCS continuing to provide updates and guidance to ensure public safety.
Residents are advised to stay indoors, use masks to avoid inhaling ash particles, and follow official announcements closely. The event underscores the importance of preparedness and rapid response in volcanic-prone regions like Negros Island.
