Kanlaon volcano records 81 earthquakes in 10 hours, PHIVOLCS warns of possible eruption

A total of 81 volcano-tectonic earthquakes were recorded at Kanlaon Volcano in just 10 hours, ranging from magnitude 0.1 to 2.9 and detected at depths of 0 to 6 kilometers.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) warned of a possible steam-driven or moderately explosive eruption due to this increased seismic activity.

This spike in activity indicates intensifying rock fracturing caused by rising magma or magmatic gases, which could lead to pressurization of the volcanic system.

Sulfur dioxide (SO2) gas emissions from the summit crater remained elevated, averaging 1,879 tonnes per day.

Alert Level 2 remains in effect over Kanlaon, signaling increased unrest, and the 4-km Permanent Danger Zone is off-limits.

Communities within a 6-kilometer radius should stay alert for potential intensification of volcanic activity, including hazards like ashfall, pyroclastic density currents, rockfalls, ballistic projectiles, and lahars.
