The Philippines' Kanlaon volcano (height: 2,465 metres) erupted on Monday (December 9, 2024). Its eruptions are often phreatic, meaning they result from the interaction of magma with water, producing steam-driven explosions rather than lava flows. However, the potential for larger eruptions remains, given its status as an active stratovolcano.

Manila: Mount Kanlaon, located on Negros Island, erupted around 4pm (local time) on Monday, leading the Philippine Institute of Volcanology and Seismology (Phivolcs) to raise its alert to Level 3, signaling “magmatic unrest.”

The eruption produced a thick ash plume that rose 3,000 metres into the air and drifted west-southwest. Phivolcs reported the release of dangerous pyroclastic materials based on thermal images.

Explosive eruptions

“This alert means a magmatic eruption has started and could lead to more explosive eruptions,” the agency warned.

Local authorities were advised to evacuate residents within a six-kilometer radius of the volcano. Videos shared online showed the volcano spewing large clouds of smoke.

Close watch

Phivolcs Director Teresito Bacolcol stated that the agency is still gathering more data about the eruption.

Prior to this event, Kanlaon recorded six volcanic earthquakes, a 16-minute ash emission, and 4,638 tonnes of sulfur dioxide release on Sunday, with a moderate ash plume reaching 300 meters.

The volcano has been under close watch since its June 3 eruption, with its ongoing unrest requiring continuous monitoring.
