PHIVOLCS: Minor Strombolian activity on Day 148 of Mayon's effusive eruption

State volcanologists observed minor Strombolian activity at Mayon Volcano on Tuesday night, June 2, 2026 amid its 148th day of effusive eruption.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) shared sped-up camera footage of the low-level volcanic explosions that was recorded from 6:56 p.m. to 6:59 p.m.

“Effusive eruption at Mayon Volcano continues for the 148th consecutive day, generating incandescent lava flows and rockfalls,” PHIVOLCS said on its social media accounts.

Earlier in the day, PHIVOLCS reported that lava flowed along the Basud, Bonga, and Mi-isi gullies, aside from seven volcanic earthquakes, 226 rockfall events, and one pyroclastic density current (PDC) signal.

Alert Level 3 – which indicate intensified unrest or magmatic unrest – is still in effect over the volcano and entry into its six-kilometer Permanent Danger Zone (PDZ) is prohibited. — JMA, GMA News
