Mayon Volcano recorded lava dome activity and lava flows, along with 308 rockfall events and 68 pyroclastic density currents or “uson” in the past 24 hours, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS).

PHIVOLCS observed continuous lava dome growth and lava flows, along with visible glow from the crater. A moderate plume drifting in multiple directions was also recorded, accompanied by measurable ground deformation.

Mayon Volcano also emitted 1,318 tons of sulfur dioxide.

On Thursday night, several incandescent lava collapse–generated pyroclastic density currents, along with rockfalls, were observed along Mayon’s Mi-isi (south), Bonga (southeast), and Basud (east) gullies between 6:45 p.m. and 7:45 p.m.

PHIVOLCS confirmed that Alert Level 3 remains in effect.

The agency reiterated that entry into the six-kilometer Permanent Danger Zone (PDZ) is strictly prohibited, and that access to the Extended Danger Zone (EDZ) without proper vigilance is not allowed.

PHIVOLCS also advised that flying aircraft close to the volcano should be prohibited.

Residents and visitors in nearby areas are warned to prepare for potential hazards, including falling rocks, lava or rock fragments, lava flows, pyroclastic flows, minor eruptions, and lahar flows in case of heavy rainfall.
