Mayon Volcano: Ongoing Eruption and Alert Level 3 – February 2026

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) continues to monitor Mayon Volcano as it experiences an ongoing effusive eruption, marked by lava flows and intensified activity. As of February 24, 2026, the volcano remains at Alert Level 3, indicating an increased tendency towards a hazardous eruption.

Recent Activity and Observations

Over the past 24 hours, lava effusion and lava flows have been observed on the Basud, Bonga, and Misi gullies [1]. Monitoring data reveals significant activity within the volcano, including four volcanic earthquakes, 305 rockfall and pyroclastic density current signals, and a “fair” crater glow visible to the naked eye [1], [2].

On February 23, 2026, Mayon Volcano released 3,891 tonnes of sulfur dioxide per day, indicating rising magma [2]. PHIVOLCS has also observed an obscured plume and ground deformation, describing the volcano edifice as “inflated,” suggesting internal pressure building [2].

As of February 17, 2026, lava flow lengths reached 3.8 km in the Basud gully, 1.6 km in the Bonga gully, and 1.3 km in the Mi-isi gully [3]. Minor Strombolian activity and 497 seismically detected rockfalls were also recorded [3].

Alert Level and Hazards

Mayon Volcano remains at Alert Level 3, signifying that an eruption is possible within days or weeks [1]. PHIVOLCS strictly prohibits entry into the 6-kilometer radius Permanent Danger Zone (PDZ) and advises against flying any aircraft close to the volcano [1].

Potential hazards include rockfalls, landslides, avalanches, ballistic fragments, lava flows, pyroclastic density currents, moderate-sized explosions, and lahars during heavy rainfall [1].

Ongoing Monitoring and Recommendations

PHIVOLCS continues to closely monitor Mayon Volcano and provide updates as the situation evolves. The ongoing monitoring is crucial for understanding the volcano’s behavior and protecting local populations [2].
