KANLAON VOLCANO ADVISORY
9 September 2024
11:30 PM
This is a notice of increased seismic activity at Kanlaon Volcano.
A total of twenty-five (25) volcano-tectonic or VT earthquakes have been recorded by the Kanlaon Volcano Network since 8:32 AM this morning, with the last 22 having been recorded beginning 10:35 PM this evening. Canlaon City, Negros Oriental residents report that at least five of these earthquakes were felt. VT earthquakes are generated by rock fracturing processes and the increase in VT activity may possibly precede eruptive activity.
The public is reminded that Alert Level 2 (increasing unrest) prevails over Kanlaon, but that current seismic activity may lead to eruptive unrest and an increase in the Alert Level. The public is strongly advised to be ready and vigilant, and to avoid entry into the four (4) kilometer-radius Permanent Danger Zone (PDZ) to minimize risks from volcanic hazards such as pyroclastic density currents, ballistic projectiles, rockfall and others. In case of ash fall events that may affect communities downwind of Kanlaon’s crater, people should cover their nose and mouth with a damp, clean cloth or dust mask. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as ash and ballistic fragments from sudden eruption can be hazardous to aircraft. Communities living beside river systems on the southern and western slopes, especially those that have already experienced lahars and muddy streamflows, are advised to take precautionary measures when heavy rainfall over the volcano has been forecast or has begun.
DOST-PHIVOLCS maintains close monitoring of Kanlaon Volcano and any new development will be immediately communicated to all concerned stakeholders.
