THE Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised Mayon Volcano to Alert Level 3 on Friday following a moderately explosive eruption that began at 11:53 a.m. and remained ongoing as of the latest advisory.
The event produced a grayish plume rising approximately 3,000 meters above the crater, drifting toward the west‑southwest. Alert Level 3 indicates increased tendency toward a hazardous eruption, with magma now at or near the crater and an eruption possible within weeks should unrest continue to intensify.
PHIVOLCS confirmed Mayon has entered a new phase of magmatic activity marked by frequent volcanic earthquakes, tremors, elevated sulfur dioxide emissions, sustained crater glow, and swelling of the volcano edifice.
Communities within the 6‑kilometer Permanent Danger Zone (PDZ) have been strongly advised to evacuate immediately due to the growing threat of lava flows, rockfalls, and fast‑moving pyroclastic density currents that may affect upper and middle slopes. Ashfall is anticipated in the Albay municipalities of Daraga, Camalig, Guinobatan, and surrounding areas.
Authorities have also warned residents to remain vigilant against potential lahars and sediment‑laden streamflows along rivers and channels draining the volcano, particularly during heavy rains. Civil aviation authorities have been directed to avoid the airspace near Mayon’s summit, as sudden ash emissions pose significant risks to aircraft engines. PHIVOLCS continues to monitor the situation closely and has urged the public to follow official updates and all safety instructions from local disaster response teams.
