Overview
- Nearly 3,000 residents have been moved from communities within the 6‑kilometre permanent danger zone as authorities enforce no‑entry rules and set up shelters.
- PHIVOLCS reported intensified dome‑collapse events on January 6 that generated pyroclastic density currents extending up to about 2 kilometres from the crater.
- Monitoring since January 1 logged 346 rockfalls and four volcanic earthquakes, with ground deformation data showing persistent inflation since mid‑2024.
- The Tokyo VAAC on January 7 detected a brief ash emission to roughly 2,700 meters, prompting aviation advisories to avoid flights near the summit.
- Officials describe ongoing effusive activity as a quiet eruption, while noting no sustained spikes in volcanic earthquakes or sulfur dioxide emissions as monitoring continues.
