The ongoing effusive eruption of Mayon Volcano continued for the 18th consecutive day on January 24, 2026, with lava flows extending approximately 1.3 to 3.2 kilometers from the summit crater.

Volcanic activity generated incandescent lava flows, pyroclastic density currents or “uson,” and rockfalls along the Mi-isi, Bonga, and Basud Gullies, according to monitoring data from the Mayon Volcano Observatory.

As of 12 AM on Sunday, the PHIVOLCS reported that Mayon recorded one volcanic earthquake, one episode of continuous volcanic tremor, 253 rockfall events, and 44 pyroclastic density currents or “uson.”

PHIVOLCS also noted that crater glow or banaag was visible, the sulfur dioxide flux reached 2,327 tons per day, and a 600-meter-high volcanic plume was observed drifting toward the southwest and northeast, indicating moderate steam emission.

Ground deformation data further showed inflation of the volcano, suggesting continued magma movement beneath the edifice.

Alert Level 3 remains in effect, with authorities reiterating the strict prohibition of entry into the six-kilometer Permanent Danger Zone due to persistent volcanic hazards.
