LEGAZPI CITY — The Philippine Institute of Volcanology and Seismology (PHIVOLCS) announced on Tuesday that Mayon Volcano’s status has been elevated from Alert Level 2 to Alert Level 3, signaling an increased tendency toward a hazardous eruption.
In a bulletin issued at 1:20 p.m., PHIVOLCS explained that the escalation was due to the collapse of the growing lava dome at the summit, which generated pyroclastic density currents (PDCs), locally known as “uson.” The agency reported 346 rockfall events and four volcanic earthquakes between January 1 and 6, with nighttime incandescence observed at the crater, indicating fresh lava extrusion.
“DOST-PHIVOLCS is now raising the alert status of Mayon Volcano from Alert Level 2 to Alert Level 3. This means that Mayon is exhibiting magmatic eruption of a summit lava dome with increased chances of lava flows and hazardous PDCs,” the agency stated.
Following the announcement, the Albay Provincial Disaster Risk Reduction and Management Council (PDRRMC) ordered the evacuation of residents within the six‑kilometer Permanent Danger Zone (PDZ). Local disaster offices were directed to monitor the situation continuously and submit updates to the Albay Public Safety and Emergency Management Office (APSEMO). Schools located inside the PDZ have suspended classes, while evacuation centers have been activated.
Authorities warned against any human activity in the danger zone, including farming, harvesting, or mountain climbing. The Philippine National Police has deployed personnel to secure affected areas and assist in evacuation efforts.
PHIVOLCS reminded the public that Alert Level 3 indicates a magmatic eruption is ongoing, with increased risks of lava flows, rockfalls, and pyroclastic currents. Residents outside the PDZ were advised to remain vigilant and heed official advisories.
Mayon Volcano, known for its near-perfect cone, last exhibited heightened activity in mid‑2023, when thousands of residents were displaced during a prolonged period of unrest.
