PHIVOLCS Bulletin (January 10, 2026) – Mayon Volcano remains at Alert Level 2 (increasing unrest), with moderate volcanic activity recorded in the past 24 hours.
Key Observations (January 9, 2025 – January 10, 2026)
- Volcanic Earthquakes: 12 low-frequency volcanic earthquakes (LFVQs) – slight decrease from previous days.
- Tremor Events: Continuous volcanic tremor with durations of 2–5 minutes each, indicating persistent magmatic or hydrothermal activity.
- Plume Emissions: Moderate emission of white steam-laden plumes reaching 300–800 meters height, drifting southwest and west-southwest.
- Sulfur Dioxide (SO₂) Flux: Elevated at ~1,200–1,800 tonnes per day (still above baseline but stable).
- Ground Deformation: Slight inflation of the edifice continues (detected via precise leveling and InSAR).
- Rockfalls: Occasional small rockfalls and incandescent avalanches observed in the upper slopes.
No magmatic eruption is imminent, but the risk of sudden phreatic (steam-driven) explosions, rockfalls, and pyroclastic density currents (PDCs) remains high within the 6-km Permanent Danger Zone (PDZ).
Safety Reminders
- Strictly prohibited: Entry into the 6-km PDZ.
- High-risk areas: Barangays in Guinobatan, Camalig, Daraga, and Legazpi City within the extended danger zone.
- Authorities: DILG and local governments continue enforcing evacuations and monitoring.
- Aviation: No-fly zone remains in effect within 10 km of the crater.
The volcano is still restless. PHIVOLCS maintains 24/7 monitoring and will issue updates if activity escalates toward Alert Level 3.
