Mayon Volcano continues to show intensified magmatic unrest as the Philippine Institute of Volcanology and Seismology (Phivolcs) maintains the volcano under Alert Level 3 following increased activity recorded over the past 24 hours.
In its latest bulletin covering observations from 12 a.m. on January 6 to 12 a.m. on Wednesday, January 7, Phivolcs reported 131 rockfall events and five pyroclastic density currents (PDCs), indicating ongoing instability at the volcano’s edifice.
Phivolcs also noted a faint crater glow, visible only through a telescope, suggesting the presence of hot magma near the summit crater.
Sulfur dioxide (SO₂) emissions were measured at an average of 702 tonnes per day on January 5, signaling continued degassing from the volcano.
Phivolcs said Mayon also emitted a moderate volcanic plume that drifted toward the west-northwest and west-southwest, while ground deformation data showed that the volcano remains inflated—an indicator of magma intrusion beneath the surface.
Despite the heightened unrest, no volcanic earthquakes were recorded in the past 24 hours, according to Phivolcs’ seismic monitoring.
Phivolcs reiterated that entry into the six-kilometer Permanent Danger Zone (PDZ) is strictly prohibited, while access to the Extended Danger Zone (EDZ) is not allowed without extreme vigilance.
It also warned against flying aircraft close to the volcano, citing potential hazards from ash emissions and ballistic fragments.
Phivolcs reminded the public and local government units that Mayon Volcano may still generate dangerous events, including rockfalls, landslides, or avalanches; pyroclastic density currents; ballistic projectiles; lava flows and lava fountaining; moderate explosive eruptions; and lahars during heavy and prolonged rainfall.
Mayon Volcano, located in the province of Albay, is among the country’s most disaster-prone areas due to its frequent eruptions and exposure to typhoons.
Phivolcs urged residents, disaster managers, and local officials to remain alert and to strictly follow evacuation and safety protocols as volcanic activity continues to evolve.
