Mayon Volcano logs 'minor' fountain activity as eruption enters 89th day

Mayon Volcano recorded minor Strombolian activity early Sunday, even as its ongoing effusive eruption entered its 89th consecutive day, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS) in a post on its official X account.

Time-lapse footage from the Mayon Volcano Observatory in Legazpi City showed activity observed between 12:32 a.m. and 12:39 a.m. on April 5, 2026, based on monitoring data.

Strombolian activity is a type of volcanic eruption in which a volcano releases bursts of lava, gas, and small fragments of rock in short, explosive spurts.

Instead of one large, continuous explosion, a Strombolian activity consists of regular “puffs” or bursts from the volcano. These bursts can eject glowing lava into the air and create small lava fountains, which may fall back around the crater.

State volcanologists said the volcano continues to generate incandescent lava flows, pyroclastic density currents (PDCs) or “uson,” and rockfalls as magma steadily extrudes from its crater.

Alert Level 3 remains in effect over Mayon Volcano, indicating increased unrest and a relatively high level of volcanic activity.

Authorities continue to strictly prohibit entry into the 6-kilometer Permanent Danger Zone due to the risks posed by sudden eruptions, lava flows, and hazardous volcanic materials.

Residents and local government units are advised to remain vigilant and follow evacuation and safety protocols as monitoring continues.—MCG, GMA News
