Mayon Volcano warning escalated to Alert Level 3 following explosive event

Authorities in the Philippines have elevated the warning status for Mayon Volcano following an explosive event on Friday, October 30. The Philippine Institute of Volcanology and Seismology, commonly known as Phivolcs, placed the volcano under Alert Level 3 after an eruption occurred late in the morning.

The midday explosion, described by scientists as moderately explosive, took place at 11:53 a.m. and sent a dense cloud of ash rising three kilometers into the sky above the crater. Volcanologists indicated that the event signals the start of a fresh phase of magmatic activity inside the Albay province landmark.

Residents across nearby communities have been instructed to prepare for ashfall. Phivolcs singled out the Albay municipalities of Guinobatan, Camalig, and Daraga, alongside neighboring districts, as areas likely to be affected by the falling volcanic debris.

With the shift to Alert Level 3, the agency called for the immediate evacuation of people living within the designated six-kilometer permanent danger zone surrounding the summit. Experts warned that the area faces heightened threats from potential lava output, rockfalls, and pyroclastic density currents—rapid avalanches of searing gas, fragmented rocks, and ash that rush down slopes and obliterate everything along their path.

Phivolcs noted that hazardous flows and streams of molten rock are increasingly probable on the middle and higher flanks of Mayon over the coming days and weeks. The monitoring agency also urged heightened caution regarding lahars and heavy sediment flows traveling through river channels that lead down from the volcanic structure.

Mayon has experienced recurrent adjustments to its threat assessment throughout 2026. State volcanologists first upgraded its status to Alert Level 2 at the start of January before elevating it to Level 3 shortly afterward. The mountain remained at that higher tier for approximately seven months before being lowered back to Level 2 in early August, where it had remained until Friday's explosive surge. The alert scale utilized by the Philippines spans from Level 0, denoting calm conditions, to Level 5, which signifies an ongoing hazardous eruption.
