Government scientists on Friday afternoon, October 7, 2022 raised Alert level 2 for Mayon Volcano in Albay Province.

Lately, Mayon has been showing signs of restlessness, and its lava dome has inflated.

DOST-PHIVOLCS issued a public notice of alert level raise, from Alert Level 1 to Alert Level 2 of Mayon Volcano.

DOST-PHIVOLCS said the Alert Level status of Mayon Volcano was raised from Alert Level 0 to Alert Level 1 on 21 August 2022, monitored parameters have been generally unremarkable.

Daily visual and camera monitoring of the summit crater revealed a continued aseismic growth of its lava dome.

As of 4 October 2022, the lava dome has increased in volume by approximately 48,000m3 since 20 August 2022.

Ocular inspection of the summit during an aerial survey this morning confirmed the presence of freshly extruded lava at the base of the summit lava dome.

The public is strongly advised to be vigilant and desist from entering the six (6) kilometer-radius Permanent Danger Zone (PDZ) to minimize risks from sudden explosions, rockfall and landslides.

In case of ash fall events that may affect communities downwind of Mayon’s crater, people should cover their nose and mouth with damp, clean cloth or dust mask. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as ash from any sudden eruption can be hazardous to aircraft.

DOST-PHIVOLCS maintains close monitoring of Mayon Volcano and any new development will be communicated to all concerned stakeholders.
