Mayon Volcano remained under Alert Level 3 on Tuesday, January 13, 2026, as state volcanologists recorded 206 rockfall events and 63 pyroclastic density currents (PDCs) over the past 24 hours.

In its 24-hour monitoring report covering 12 a.m. on Monday, January 12, to 12 a.m. on Tuesday, January 13, PHIVOLCS said Mayon continued to exhibit lava dome growth and lava flow effusion.

PHIVOLCS also observed fair crater glow visible to the naked eye, indicating the presence of hot material at the summit. Sulfur dioxide emission remained elevated at 526 tonnes per day, based on measurements taken on January 11.

Volcanic gas plumes rose up to 1,000 meters above the crater and drifted toward the west-southwest and southwest. Ground deformation data showed that the volcano’s edifice remained inflated, a sign of continued magma intrusion.

PHIVOLCS reiterated that entry into the 6-kilometer Permanent Danger Zone is prohibited strictly, and warned against unguarded access to the Extended Danger Zone. The agency also advised that flying any aircraft close to the volcano remains unsafe.

Possible hazards include rockfalls, lava flows, lava fountaining, pyroclastic density currents, moderate explosions, and lahars during periods of heavy and prolonged rainfall.

PHIVOLCS said it continues to closely monitor Mayon Volcano and advised the public to remain alert and follow official advisories.
