In a volcano bulletin issued at 8 a.m., state seismologists recorded one volcanic earthquake in the country’s most active volcano during the past 24-hour observation period.

Phivolcs also observed moderate emission of white steam-laden plumes that crept downslope before drifting to the northwest and southwest.

Faint crater glow from the summit could be observed at night, it said.

On Feb. 24, Wednesday, sulfur dioxide (SO2) emission was measured at an average of 110 tonnes per day.

“Ground deformation data from continuous GPS monitoring indicate that the edifice is still inflated relative to July 2019 despite a period of general deflation since July-August 2020, and is undergoing short-term inflation since November 2020 except on the southwestern slope. Deflation of the edifice with short-term inflation of the northwestern slopes since December 2020 has also been recorded by electronic tilt monitoring,” read the latest volcano bulletin.

Phivolcs said Mayon Volcano remains under Alert Level 1, which means that it is at an abnormal condition.

“Although this means that presently no magmatic eruption is imminent, it is strongly advised that the public refrain from entering the 6-kilometer radius Permanent Danger Zone (PDZ) due to the perennial life-threatening dangers of rockfalls, landslides/avalanches at the middle to upper slope, sudden ash puffs and steam-driven or phreatic eruptions from the summit,” it said.

Phivolcs also urged the public to avoid active stream or river channels and those identified as perennially lahar-prone areas on all sectors of the volcano especially during heavy and prolonged rainfall.
