Lava effusion seen at Mayon on 170th day of effusive eruption, PHIVOLCS says

State volcanologists observed lava effusion anew at Mayon Volcano on Wednesday night as the volcano marked its 170th day of effusive eruption.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) shared camera footage of the lava effusion, which was recorded from 8:54 p.m. to 9:02 p.m. of June 24, 2026.

Mayon Volcano is on its 170th consecutive day of effusive eruption, generating incandescent lava flows, pyroclastic density currents (PDCs) or “uson,” and rockfalls.

On Sunday, state volcanologists also recorded lava effusion with collapse-fed PDCs at the volcano.

State volcanologists warned that Alert Level 3 – which means intensified or magmatic unrest – remains in effect over the volcano.

Entry into Mayon Volcano’s six-kilometer permanent danger zone (PDZ) is strictly prohibited, PHIVOLCS added. — JMA, GMA News
