Philippines, Mayon Volcano Activity in Region V

Update:

As of 02 May 2026, Alert Level 3 prevails over Mayon Volcano and entry into the
6-km Permanent Danger Zone remains prohibited. Mayon has been exhibiting an
effusive eruption for the 66th consecutive day, generating incandescent lava flows,
collapse-fed pyroclastic density currents (PDCs), or “uson,” and rockfalls. Mayon has
been demonstrating a brief intensification of unrest, with conditions progressing to a
near-steady state since the onset of its eruption. Lava flows have reached radial
distances of 1.3 km, 1.6 km, and 3.8 km along the Mi-isi, Bonga, and Basud Gullies,
respectively, while rockfall and PDC runouts remained confined within 3 km of the
summit crater. Residents within an 8-km radius are advised to prepare for possible
evacuation should the alert level be raised to Level 4. The civil aviation authorities
advised avoiding flights close to the summit due to ash hazards.
As of 02 May 2026, at approximately 4:28 PM, Mayon Volcano exhibited a lava flow
collapse-fed pyroclastic density current (PDC) along Mi-isi Gully on the southwestern
slopes. This event also produced rockfalls and ashfall in several municipalities in the
west-southwest area of Albay (Camalig, Guinobatan, and Ligao), lasting for about
three hours. Mayon has been demonstrating a brief intensification of unrest, with
conditions progressing to a near-steady state since the onset of its eruption. Lava
flows have reached radial distances of 3.8km, 3.2km, and 1.3 km along the Basud,
Bonga, and Mi-isi Gullies, respectively. Residents within an 8-km radius are advised
to prepare for possible evacuation should the alert level be raised to Level 4. The
civil aviation authorities advised avoiding flights close to the summit due to ash
hazards.

On 01 January 2026 at 6:00 AM, DOST-PHIVOLCS released an advisory regarding the

rise in the alert level for Mayon Volcano from Alert Level 1 (low-level unrest) to Alert

Level 2 (increasing or moderate level unrest), which indicates that there is current unrest

driven by shallow magmatic processes that could lead to hazardous magmatic eruption.

An increase in rockfall activity from the summit lava dome of Mayon Volcano has been

recorded by the visual and seismic monitors of the Mayon Volcano Network.

On 6 January 2026 at 1:20 PM, PHIVOLCS-DOST raised the alert status of Mayon

Volcano from Alert Level 2 to Alert Level 3 (increased tendency towards a hazardous

eruption). This means that Mayon is exhibiting magmatic eruption of a summit lava dome,

with increased chances of lava flows and hazardous Pyroclastic Density Currents (PDCs)

affecting the upper to middle slopes of the volcano and of potential explosive activity

within days or weeks.
