MANILA, Philippines — Kanlaon Volcano continues to operate under Alert Level 2, signaling moderate unrest, following the release of ash-laden plumes earlier this week.
Recent Volcanic Activity
Observations from the past 24 hours, spanning early Wednesday to early Thursday, revealed grayish ash emissions rising up to 900 meters above the summit crater. These plumes drifted northwest, accompanied by a single prolonged emission event lasting about three and a half hours. Seismic monitors detected three volcanic earthquakes during this period.
Monitoring Data and Hazards
Sulfur dioxide emissions measured 1,662 tonnes per day as of the previous day, with earlier plumes reaching 800 meters and shifting in various directions including southwest and west. Ground deformation studies indicate ongoing inflation of the volcano’s structure, pointing to persistent magmatic activity beneath the surface.
Authorities advise against entering the four-kilometer permanent danger zone around the volcano or operating aircraft nearby, due to risks of sudden steam-driven eruptions or other precursory events. The volcano, located between Negros Occidental and Negros Oriental provinces, has shown elevated but moderate unrest in recent days.
Ongoing Vigilance
Monitoring efforts remain intensive, tracking seismicity, gas output, and ground movements. Residents and visitors are encouraged to stay informed through official channels and adhere to safety guidelines while Alert Level 2 is in place.
