Kanlaon Volcano in Visayas remains restless, emitting ash seven times over a span of one hour and 40 minutes on Friday, according to the latest Philippine Institute of Volcanology and Seismology (Phivolcs) bulletin released Saturday.

The ash emissions were accompanied by 11 volcanic earthquakes and seven volcanic tremors, each lasting between 17 to 100 minutes. The volcano also released 3,994 tons of sulfur dioxide, signaling continued activity beneath the surface.

Degassing, pressure buildup continues

Observers reported moderate volcanic plumes reaching heights of 150 meters and drifting southwest, indicating continuous degassing — the sustained release of volcanic gases such as sulfur dioxide.

Phivolcs also noted that the volcano’s edifice remains inflated, suggesting an ongoing buildup of pressure beneath its surface, which could potentially lead to further activity.

Kanlaon Volcano erupted on 9 December 2024, prompting Phivolcs to raise its alert status to Level 3 (magmatic unrest), which remains in effect to date.
