The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has released dramatic timelapse footage showing a dome-collapse at Mayon Volcano, as the restless peak unleashed dozens of volcanic flows on Thursday.
The summit collapse occurred at 6:51 a.m. local time, triggering a pyroclastic density current (PDC)—a fast-moving, lethal mixture of volcanic gas and rock fragments. The event sent a towering column of grayish ash roughly 1,000 meters (3,280 feet) into the sky before drifting west-northwest.
A Rapid Increase in Activity
Authorities report a significant uptick in activity at the volcano, located in the province of Albay. Since midnight on January 8, 2026, seismic instruments have recorded a total of 40 discrete PDC events, signaling a period of high instability for the volcano’s lava dome.
“The situation remains dynamic,” PHIVOLCS stated, confirming that the collapse of the lava dome is the primary driver behind the current series of hazardous flows.
Ashfall Hits Nearby Cities
Residents in several areas of Albay reported thin blankets of ash covering homes and vehicles following the morning’s activity. Affected areas include:
- Legazpi City
- Ligao City
- Bacacay
- Camalig
- Daraga (specifically Brgy. Anislag)
Health officials are advising residents in these zones to wear face masks or use damp cloths to cover their noses and mouths to avoid inhaling fine volcanic particles.
High Alert Maintained
Mayon Volcano remains under Alert Level 3, indicating a high level of unrest and the possibility of a hazardous eruption within weeks or even days.
The 6-kilometer Permanent Danger Zone (PDZ) is being strictly enforced. Authorities have reiterated that all entry into this radius is prohibited due to the constant threat of PDCs, rockfalls, and sudden explosions.
Civil aviation authorities have also been advised to caution pilots against flying near the volcano’s summit, as ash and debris can cause catastrophic engine failure.
