WATCH: Lava effusion, collapse-fed PDCs anew at Mayon Volcano

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) logged fresh occurrences of lava effusion with collapse-fed pyroclastic density currents (PDCs) on Mayon Volcano at past midnight Tuesday.

This is as the volcano’s effusive eruption persisted for the 141st day on May 26, 2026.

State volcanologists shared sped-up camera footages of lava effusion with collapse-fed PDCs along Mayon Volcano’s Bonga, Basud, and Mi-isi gullies, which were recorded at 10:53 p.m. and 11:42 p.m. Monday, and at 12:32 a.m. Tuesday.

Mayon Volcano is on its 141st consecutive day of effusive eruption, generating incandescent lava flows, PDCs or “uson,” and rockfalls.

Earlier on Monday night, PHIVOLCS also observed the occurrence of lava effusion with collapse-fed PDCs and minor Strombolian activity at the volcano.

The lava effusion with collapse-fed PDCs flowed along Mi-isi and Basud gullies at 7:20 p.m. and 7:26 p.m. of May 25.

Mayon Volcano remains under Alert Level 3, which means a state of intensified unrest or magmatic unrest.

Entry into its six-kilometer Permanent Danger Zone (PDZ) is prohibited. — JMA, GMA News
