MANILA, Philippines — Kanlaon Volcano continues to exhibit moderate unrest under Alert Level 2, with recent observations showing the release of ash-laden plumes on January 7.
Recent Volcanic Activity
Monitoring data from the past 24 hours indicate a single ash emission event that persisted for about three hours and 30 minutes. Grayish plumes rose up to 900 meters above the summit crater, drifting northwest. This activity was accompanied by three volcanic earthquakes, signaling ongoing internal processes.
Sulfur Dioxide Emissions and Ground Deformation
Sulfur dioxide flux measured 1,662 tonnes per day as of January 6, with previous plumes reaching heights of 800 meters and drifting in various directions, including southwest, west-southwest, and west. Ground deformation studies reveal inflation of the volcano’s structure, pointing to sustained magmatic activity beneath the surface.
Safety Recommendations
Authorities advise against entering the 4-kilometer Permanent Danger Zone around the volcano or operating aircraft in its vicinity, due to risks of sudden steam-driven eruptions or other precursory events. The volcano, located between Negros Occidental and Negros Oriental, has displayed elevated activity in recent days, though it remains at a moderate level.
Continuous monitoring of seismicity, gas emissions, and ground movements is underway, with officials encouraging residents to stay informed and adhere to safety guidelines while Alert Level 2 persists.
