Mayon Volcano on Wednesday continued to exhibit effusive eruption activity over the past 24 hours with lava flows and minor explosive events, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS).

In its latest bulletin, PHIVOLCS said lava continued to flow through several gullies, reaching up to 3.8 kilometers in the Basud channel, 3.2 kilometers in Bonga, and 1.6 kilometers in Mi-isi, according to a report by Joviland Rita on GMA News Online.

Episodic minor strombolian activity and short-lived lava fountaining were observed at the summit crater. Crater glow was described as “fair” and visible to the naked eye at night.

A total of 11 volcanic earthquakes were recorded, including three volcanic tremors lasting between three to six minutes.

A total of 283 rockfall events and 17 pyroclastic density current signals were recorded.

Moderate emission plumes drifting westward were also observed from Mayon. Also, sulfur dioxide emissions from the volcano reached 2,184 tonnes on Tuesday.

Ground deformation data indicated short-term deflation of the volcanic edifice, alongside localized inflation on the northeastern flank.

PHIVOLCS also reminded the public that entry into the six-kilometer radius permanent danger zone remains strictly prohibited due to persistent hazards.

The agency also warned against flying aircraft close to the volcano.

Among the possible dangers are rockfalls, landslides, ballistic fragments, lava flows, lava fountaining, pyroclastic density currents, and moderate-sized explosions.

Lahars may also occur during periods of heavy and prolonged rainfall.
