Phivolcs: 15 quakes recorded at Mayon in last 24 hours


Restive Mayon Volcano in Albay showed signs of increased activity with 15 volcanic quakes in the last 24 hours, state volcanologists said Sunday.

The Philippine Institute of Volcanology and Seismology (Phivolcs) also noted one rockfall-related event and moderate steam emission in the same time period.

“Mayon Volcano’s seismic network recorded 15 volcanic earthquakes and one rockfall-related event during the past 24 hours. Moderate emission of white steam that reached a maximum height of 400 meters above the summit crater was observed drifting west–southwest and southwest,” it said in its Sunday update.

Phivolcs also said a crater glow was observed at Intensity II (can be seen by the naked eye) Saturday night.

It said Alert Level 1 remains over Mayon Volcano, meaning that while no eruption is imminent, the public should not enter the 6-km radius Permanent Danger Zone (PDZ) due to the continuing threat from sudden small explosions and rockfalls from the upper and middle slopes of the volcano.

“Active stream/river channels and those perennially identified as lahar-prone areas in the southern sector should also be avoided especially during bad weather conditions or when there is heavy and prolonged rainfall,” it said.

In Batangas, Phivolcs said at least four volcanic quakes were recorded at Taal Volcano in the last 24 hours.

Phivolcs also noted weak to moderate steaming from known thermal vents was observed in the same period.

Bulusan Volcano’s status remains at Alert Level 1, where the source of activity is hydrothermal and shallow.

“Entry to the 4-km radius PDZ is strictly prohibited, since the area is at risk to sudden steam and ash explosions. Due to the prevailing wind direction, residents in the northwest and southwest sectors of the volcano are reminded to take precautions against ash falls,” it said.

Meanwhile, Phivolcs said four volcanic earthquakes were noted at Taal in Batangas in the last 24 hours.

Alert Level 2 remains over Taal Volcano, with the interpretation that magma has been intruding towards the surface.

Phivolcs reminded the public the Main Crater, Daang Kastila Trail and Mt. Tabaro are strictly off-limits because sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate.

“In addition, it is reminded that the entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strictly not recommended,” it said. — LBG, GMA News
