Mayon Volcano in Albay generated a hazardous flow of hot gas, ash, and fragmented volcanic material on Friday, state volcanologists reported.
The Philippine Institute of Volcanology and Seismology (Phivolcs) said the event resulted from a lava-collapse, producing a pyroclastic density current that moved rapidly down the volcano’s slopes.
Monitoring data showed that the ash-laden flow was still ongoing as of Friday afternoon, indicating sustained surface instability rather than an isolated occurrence.
Phivolcs noted that lava-collapse events happen when accumulated lava becomes unstable and breaks apart, releasing a dense mixture of volcanic debris and hot gases.
These fast-moving currents are considered highly dangerous due to their speed, heat, and ability to travel quickly within hazard zones.
The agency said the observed activity was consistent with Mayon’s continuing unrest and did not mark a sudden escalation beyond current conditions.
Alert Level 3 remained in effect over the volcano, signaling magmatic unrest and the possibility of further hazardous activity.
Authorities reiterated that entry into the permanent danger zone is prohibited and advised nearby communities to stay alert for official updates as monitoring continues.
