Phivolcs: 8 quakes recorded at Taal (video inside)


While Taal Volcano in Batangas continued to show signs of restlessness, two other volcanoes in the Bicol Region showed signs of increased activity in the last 24 hours.

The Philippine Institute of Volcanology and Seismology said Bulusan in Sorsogon had four volcanic quakes while Mayon in Albay had two.

In its Wednesday update, Phivolcs said the seismic network around Taal recorded eight volcanic earthquakes during the past 24 hours.

"One of these events which occurred on 1:47 p.m. (Tuesday) was felt at Intensity II by residents in Barangay Calauit at the southeastern part of Taal Volcano island with rumbling sounds," it said.

Also, water temperature at the Main Crater Lake was at 30.5 degrees Celsius.

Phivolcs said Alert Level 2 remains hoisted over Taal Volcano with the interpretation that magma has been intruding towards the surface, as shown by carbon dioxide being released in the Main Crater Lake and increase in seismic activity.

It maintained the public should stay away from the Main Crater, Daang Kastila Trail and Mt. Tabaro.

Bulusan watch

At Bulusan, Phivolcs said the seismic network around it detected four volcanic earthquakes during the past 24 hours, although steaming was not observed due to thick clouds covering the summit Tuesday.

Bulusan Volcano’s status remains at Alert Level 1, with entry to the 4-km Permanent Danger Zone strictly prohibited.


At Mayon, Phivolcs recorded two volcanic earthquakes during the past 24 hours, and moderate emission of white steam drifting northwest.

Phivolcs said Alert Level 1 remains over Mayon Volcano.

Phivolcs said that although no eruption is imminent, it advised the public to refrain from entering the 6-km radius permanent danger zone.

"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 added.
