175 volcanic temblors recorded in Taal

State seismology bureau Philippine Institute of Volcanology and Seismology (Phivolcs) on Saturday revealed that it has registered 175 volcanic earthquakes around the Taal Volcano in 24 hours.

Phivolcs — in its advisory — said that the activity around the main crater “consisted of moderate emission of steam-laden plumes from fumarolic vents that rose 80 to 100 meters high.”

The state seismology bureau added that on top of the 125 volcanic earthquakes, it also recorded 131 volcanic tremors around the Batangas volcano, lasting between one and 15 minutes.

To recall, the Phivolcs also recorded 252 volcanic earthquakes within 24 hours in Taal in a 15 March advisory and with the earthquakes and tremors felt, Taal still stands at Alert Level 2, which signifies increased unrest.

Under Alert Level 2, sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ash fall and expulsions and lethal accumulations of volcanic gas may occur and threaten areas within the Taal Volcano island.

The State seismology bureau also recommended anew that entries into some areas such as the Taal Volcano Island, Taal’s Permanent Danger Zone and the vicinities of the main crater and Daang Kastila fissure “must remain strictly prohibited.”

It also advised local government officials to “continuously assess and strengthen the preparedness” of barangays previously evacuated around Taal lake in case of “renewed unrest.”

Phivolcs also said it was “closely monitoring” volcanic activity around Taal, with significant developments to be “immediately” communicated.

Taal’s eruption in January last year displaced some 350,000 people and brought ash fall around Batangas and surrounding areas, including Metro Manila.
