Metro Manila (CNN Philippines, October 7) — The Philippine Institute of Volcanology and Seismology (Phivolcs) on Friday declared Alert Level 2 on Mayon Volcano or with increasing unrest.

“This means that there is current unrest driven by shallow magmatic processes that could eventually lead to phreatic eruption or even precede hazardous magmatic eruption,” Phivolcs said.

The agency added that “daily visual and camera monitoring of the summit crater revealed a continued aseismic growth of its lava dome.”

As of Oct. 4, Phivolcs said the lava dome has increased in volume since Aug. 20. In an ocular Friday morning, authorities confirmed the presence of fresh lava at the base of the summit dome.

To minimize risks from sudden explosions, rockfall, and landslides, Phivolcs advised the public to remain vigilant and avoid entering the six-kilometer radius permanent danger zone.

In case of ashfall, affected residents are advised to cover their nose and mouth with damp, clean cloth or dust mask.

Flying close to Mayon’s summit must also be avoided as ash from any sudden eruption can be hazardous to aircraft, the agency added.
