Philippine state volcanologists have upgraded the alert level of Mayon Volcano in Albay province to Alert Level 3. This is in response to the onset of dome collapse pyroclastic density current, indicating a magmatic eruption of a summit lava dome. The increased alert signifies higher chances of lava flows and hazardous pyroclastic density currents affecting the upper to middle slopes of the volcano.
The Philippine Institute of Volcanology and Seismology reported that the repeated collapses of the unstable summit dome have led to more rockfall events. Since January 1, 2026, a total of 346 rockfall events and four volcanic earthquakes have been recorded. The institute has advised evacuating the six-kilometer permanent danger zone due to risks of PDCs, lava flows, rockfalls, and other volcanic hazards.
Authorities are urging residents near Mayon to stay vigilant and follow guidance from local disaster risk reduction officials. The institute also recommends increased vigilance against pyroclastic density currents, lahars, and sediment-laden streamflows along channels draining the volcano.
Earlier this year, the PHIVOLCS raised the alert level of Mayon Volcano due to increased volcanic activity. The escalation from alert level 1 to alert level 2 indicates movement of magma beneath the volcano, raising the potential for sudden explosive activity. The public is strongly advised to avoid the six-kilometer-radius Permanent Danger Zone to reduce risks from explosions and related hazards.
