PHIVOLCS logs volcanic quakes in Bulusan, Kanlaon, Taal

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) on Wednesday logged volcanic earthquakes in three volcanoes in the country under Alert Level 1.

Based on the latest report, PHIVOLCS said at least 12 volcanic earthquakes were recorded in Bulusan Volcano in Sorsogon province while 17 volcanic earthquakes were detected in Kanlaon Volcano in Negros in the past 24 hours.

Taal Volcano in Batangas, on the other hand, had one volcanic tremor with a six minutes long and low-level background tremor.

Bulusan Volcano also emitted 437 tonnes of sulfur dioxide on July 19, while it also had “moderate emission” of plumes going up to 200 meters tall and drifted west-northwest direction.

The volcano edifice is also inflated, according to PHIVOLCS.

Meanwhile, Kanlaon Volcano emitted 151 tonnes of sulfur dioxide last May 1, while the height of the plume emitted by the volcano cannot be measured by the agency since their view was obscured.

PHIVOLCS said the volcano edifice is “slightly inflated.”

The agency reported that Taal Volcano emitted 2,342 tonnes of sulfur dioxide on July 18, while it had “moderate emission” of plumes going up to 600 meters drifted southwest.

It added that the Tall Volcano Island and Tail Caldera were deflated since October 2021.

The three volcanoes remained under Alert Level 1 or low-level unrest, according to the agency.

PHIVOLCS, however, warned entry into the four kilometer radius permanent danger zone and entry without vigilance into the extended danger zone is still not allowed in Bulusan Volcano and Kanlaon Volcano.

Meanwhile, entry into Taal Volcano Island, a permanent danger zone, especially the main crater and Daang Kastila fissures, and occupancy and boating on Taal Lake is not allowed.

The agency said flying any aircraft close to the volcanoes is strictly discouraged as possible sudden steam-driven or phreatic eruptions may occur, while volcanic earthquakes, minor ash fall, lethal accumulations or expulsions of volcanic gas may happen at Taal Volcano.—Richa Noriega/AOL, GMA News
