Kanlaon Volcano Spews Ash Anew; PHIVOLCS Maintains Alert Level 2

NEGROS ISLAND, Philippines — October 24, 2025

The Kanlaon Volcano in Negros Island erupted briefly on Friday evening, releasing a light gray ash plume that drifted northeast, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS).

The agency confirmed that the ash emission was recorded around 8:05 p.m. and lasted for several minutes. Although the exact height of the ash plume was not disclosed, previous similar events this month reached up to 600 meters above the crater.

Mount Kanlaon, the highest peak in the Visayas and one of the most active volcanoes in the Philippines, remains under Alert Level 2, signifying increased unrest due to volcanic gas emission, seismic activity, and ground deformation. PHIVOLCS strongly warned the public against entering the 4-kilometer Permanent Danger Zone (PDZ) due to possible sudden steam-driven explosions.
Local disaster response offices in Negros Occidental and Negros Oriental have not reported any injuries or damage. However, officials urged residents in the towns of La Carlota, La Castellana, Canlaon City, and Bago City to remain vigilant as light ashfall and sulfur odors may persist.

PHIVOLCS advised affected communities to close doors and windows, wear face masks, and avoid outdoor activities during ashfall. It also reminded the public not to drink or use water collected from open sources that may be contaminated with volcanic ash.
PHIVOLCS continues to closely monitor Kanlaon Volcano’s seismic activity, sulfur dioxide emissions, and ground deformation. The agency said that while a major eruption is not imminent, sudden phreatic (steam-driven) explosions could occur without warning.

Aviation authorities have been alerted as ash clouds can pose risks to aircraft operations in nearby flight paths.

Authorities reminded the public that Kanlaon’s alert level may be raised if stronger activity is detected. Residents are urged to follow official advisories and rely only on verified updates from PHIVOLCS and local government units.
