Mayon Volcano recorded a total of 256 rockfall events and pyroclastic density currents (PDCs), locally known as “uson,” within a 24-hour period, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS).

PHIVOLCS said lava effusion from the volcano continues, while crater glow remains visible from the summit.

On Saturday, Mayon Volcano emitted 777 tons of sulfur dioxide.

Moderate plumes were also observed rising from the crater, reaching up to 200 meters high before drifting toward the northeast.

PHIVOLCS added that the volcano’s edifice remains inflated, indicating continued movement of magma beneath the volcano.

Alert Level 3, or Intensified Unrest/Magmatic Unrest, remains in effect over Mayon Volcano.

The agency reiterated that entry into the six-kilometer Permanent Danger Zone (PDZ) is strictly prohibited, and that access to the Extended Danger Zone (EDZ) without proper vigilance is not allowed.

PHIVOLCS also advised that flying aircraft close to the volcano should be prohibited.
