No volcanic quakes in Taal Volcano in past 24 hours, but Alert Level 3 remains —PHIVOLCS

Taal Volcano in Batangas did not have any volcanic earthquake in the past 24 hours, but Alert Level 3 remains in effect, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said on Monday.advertisement

Hot volcanic fluids continued upwelling the main crater in the past 24 hours, generating plumes 1,000 meters tall before drifting southwest, PHIVOLCS said in its 8 a.m. bulletin.

“Wala pong ibinubugang abo ang Taal Volcano kundi usok lamang sa nakalipas na 24 oras. Puti po ang usok na lumalabas at wala namang pagyanig na naitala sa nakalipas na 24 na oras,” PHIVOLCS Officer-in-Charge and Science Undersecretary Renato Solidum Jr. said in an interview on GMA News’ Unang Balita on Monday.

(Taal Volcano has not emitted ash, but only plumes the past 24 hours. White smoke is coming out of the crater and no volcanic earthquakes have been recorded in the past 24 hours.)

On Sunday, the volcano emitted an average of 1,140 tonnes.

Two phreatomagmatic bursts — formed through the interaction of magma and water — were recorded on Sunday morning.

PHIVOLCS said the last time the main crater lake’s temperature was measured was on February 25, and it was 63.7 degrees Celsius.

Alert Level 3 means “there is a magmatic intrusion at the Main Crater that may further drive succeeding eruptions,” PHIVOLCS said.

Magma activities

Solidum said the volcano’s magma activities have yet to end.

“Ang pag-aalboroto ng Taal Volcano o pagkakaroon ng magma activities sa Taal Volcano ay magpapatuloy pa dahilan nang magmula noong nakaraang taon, ang magma ay nasa mababaw na parte at ‘yan po ang nagdulot ng pagbuga ng maraming asupre at minsan-minsan ay pagsabog,” he said.

(Taal Volcano’s unrest or magma activities are continuing. This is because since last year, the magma is in the upper part of the volcano, and that is the cause of the sulfur dioxide emission and sometimes eruptions.)

The agency reiterated that Taal Volcano Island — a permanent danger zone — and Barangays Bilibinwang and Banyaga in the muncipality of Agoncillo and Boso-boso, Gulod and eastern Bugaan East in Laurel, Batangas should be evacuated “due to the possible hazards of pyroclastic density currents and volcanic tsunami should stronger eruptions subsequently occur.”

“All activities on Taal Lake should not be allowed at this time,” PHIVOLCS said.

It also advised lakeshore communities to be vigilant, take the necessary precautions against possible airborne ash and vog, and prepare for evacuation should volcanic activities intensify.

Likewise, PHIVOLCS advised against flying over Taal Volcano since airborne ash and ballistic fragments from sudden explosions and pyroclastic density currents such as base surges may harm aircraft.
