MANILA – Kanlaon Volcano on Negros Island emitted gray ash plumes twice on Monday morning, December 22, 2025, as part of its continuing moderate unrest, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported. The brief emissions—lasting less than an hour each—generated plumes rising 100-150 meters above the crater, drifting west, with no significant ashfall reported in nearby communities.
PHIVOLCS noted the events were captured on time-lapse footage from the Kanlaon Volcano Observatory in Canlaon City. These ash ejections follow a pattern of intermittent activity in recent months, including multiple emissions in October and November, amid elevated sulfur dioxide levels and volcanic earthquakes.
Alert Level 2 remains in effect, indicating increased unrest with potential for sudden steam-driven or phreatic eruptions. The 4-km Permanent Danger Zone around the summit is strictly off-limits, and aviation authorities are advised of possible ash hazards.
Residents in downwind areas (Negros Occidental and Negros Oriental) are urged to prepare for vog (volcanic fog) and minor ashfall, which could affect health and agriculture. Local governments maintain heightened monitoring, with no evacuation orders issued yet.
Kanlaon’s activity—ongoing since a major eruption in 2024—serves as a reminder of nature’s power during the holidays: Beautiful from afar, but vigilance is key for safety.
