Overview
- PHIVOLCS elevated Mayon to Alert Level 3 on January 6 after summit lava extrusion and dome collapse generated pyroclastic density currents.
- Authorities moved more than 2,800 residents out of the 6‑kilometre Permanent Danger Zone, with about 600 additional people evacuating voluntarily to government shelters.
- A series of pyroclastic density currents on January 6 flowed up to 2 kilometers down the Bonga (southeast) Gully, with nighttime incandescence indicating slow lava extrusion.
- The Tokyo VAAC reported a short-lived ash emission to about 2,700 meters on January 7, and civil aviation was advised to keep aircraft away from the summit due to ash hazards.
- Monitoring since January 1 recorded 346 rockfalls and four volcanic earthquakes, with ongoing inflation but relatively low sulfur dioxide output, leaving the likelihood of a large explosive eruption uncertain.
