“Moderate unrest” persists over Kanlaon Volcano as the Philippine Institute of Volcanology and Seismology (Phivolcs) observed a 10-minute ash emission from the active volcano on Monday morning, Oct. 20.
According to Phivolcs, the ash emission occurred from 7:28 a.m. to 7:38 a.m., producing grayish plumes that rose about 300 meters above the summit crater before drifting westward.
The event was captured by the Kanlaon Volcano Observatory’s IP camera in Canlaon City.
In its latest monitoring, Phivolcs said 25 volcanic earthquakes were recorded over the past 24 hours, indicating continued activity beneath the volcano.
The agency reminded the public that Alert Level 2 remains in effect, meaning the volcano is still under a state of moderate unrest and that sudden steam-driven or phreatic eruptions could occur.
Residents and visitors are advised to stay outside the four-kilometer permanent danger zone due to the risk of sudden explosions, pyroclastic density currents, rockfalls, and exposure to harmful volcanic gases.
Local government units were urged to maintain preparedness for possible evacuation scenarios, while civil aviation authorities were advised to avoid flying close to the volcano’s summit due to potential ash that could endanger aircraft.
Phivolcs also warned that heavy rainfall could generate lahars or sediment-laden streamflows in rivers and drainages surrounding the volcano.
Kanlaon Volcano, one of the most active in the Philippines, straddles the provinces of Negros Occidental and Negros Oriental on Negros Island.
