Kanlaon Volcano spews ash plumes, remains on Alert Level 2

Kanlaon Volcano on Negros Island emitted ash plumes up to 600 meters that drifted westward on Wednesday morning.

The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded the ash emission at 5:10 a.m. on September 10, 2025, with seven volcanic earthquakes and 1,248 tonnes of sulfur dioxide emission recorded in the past 24 hours.

Alert Level 2 remains in effect over Kanlaon Volcano, indicating increased unrest.

Phivolcs reiterated that entry into the four-kilometer permanent danger zone and flying aircraft close to the volcano are not allowed due to hazards such as sudden steam-driven or phreatic eruptions and precursory magmatic activity.

Following Kanlaon's activity, the Civil Aviation Authority of the Philippines (CAAP) has issued a Notice to Airmen (NOTAM) for flights near the area, setting vertical limits from the surface up to 10,000 feet.
