MANILA — Due to the commencement of dome collapse pyroclastic density current (PDC), also known as “uson,” the Philippine Institute of Volcanology and Seismology elevated the Mayon Volcano to alert level 3 on Tuesday, January 6.

In a 24-hour period from January 5 to 6, Philvolcs recorded 85 rockfall events in the volcano.

Mayon is displaying a magmatic eruption of a peak lava dome, according to the agency.

Additionally, the top to intermediate slopes of the volcano are more likely to see dangerous PDC and lava flow.

Ash fall events are probably going to happen. Phivolcs emphasized that there might be explosive activity in a matter of days or weeks.

Because of the risk of PDCs, lava flows, rockfalls, and other volcanic dangers, it warned the public not to enter the six-kilometer radius permanent danger zone (PDZ).

Additionally, it is not recommended to fly near the summit of the volcano.

On January 1, Phivolcs reported 47 rockfall events in a single day, prompting the Mayon Volcano in Albay, Bicol, to be raised to alert level 2.

According to Phivolcs, the average number of rockfall incidents per day rose from 10 in the final two months of 2025 to 21 in the final week of December.

The agency said to have seen ground deformation close to the volcano, which is a sign that hydrothermal fluids and magma might be rising to the surface.

Mayon last erupted in June of 2023.

The provinces of Ligao City, Albay, Camalig, and Guinobatan have communities on heightened alert.
