The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported high volcanic activity at Mayon Volcano on Saturday, February 21, 2026.

The agency recorded four volcanic earthquakes, 401 rockfall events, and four signals of pyroclastic density currents, locally known as uson.

Mayon remains at Alert Level 3, indicating "high" volcanic unrest. Lava continues to flow through several gullies, including Basud (3.8 km), Bonga (1.6 km), and Mi-isi (1.3 km). A faint glow from the crater is also visible, signaling ongoing volcanic activity.

PHIVOLCS reported a moderate steaming plume drifting west-southwest, and sulfur dioxide emissions reached 3,739 tons per day as of February 20.

Ground deformation monitoring shows swelling of the volcano, which is consistent with elevated magma movement beneath the surface.

Authorities continue to advise residents and visitors to avoid the high-risk danger zones around Mayon, particularly the areas surrounding the active lava channels.
