Mayon Volcano continued to pose hazards to nearby communities as the Philippine Institute of Volcanology and Seismology (Phivolcs) recorded 308 rockfall events and 68 pyroclastic density currents from 12 a.m. on Thursday, Jan. 15, to 12 a.m. on Friday, Jan. 16.

Alert Level 3 remains hoisted over the volcano due to ongoing magmatic unrest.

Phivolcs said lava dome growth and lava effusion were still observed during the monitoring period.

Crater glow was visible and described as fair to the naked eye.

Sulfur dioxide emission reached 1,318 tons on Jan. 15, while volcanic plumes showed moderate emission drifting southwest to west-southwest.

Phivolcs reiterated that entry into the six-kilometer-radius permanent danger zone is strictly prohibited, as well as entering the extended danger zone without vigilance.

Aircraft are also barred from flying close to the volcano due to hazards from ash and volcanic debris.

Phivolcs reminded the public and local authorities that potential hazards while Alert Level 3 remains in effect include rockfalls, landslides or avalanches, ballistic fragments, lava flows and lava fountaining, pyroclastic density currents, moderate-sized explosions, and lahars during heavy or prolonged rainfall.
