BATANGAS City — The Philippine Institute of Volcanology and Seismology (Phivolcs) is poised to raise Taal volcano’s current warning to Alert Level 3 if and when her majesty continues acting up.

Sources said Saturday that decision of the Philvolcs to do just that could be based on Taal’s increased activity.

In the past 24 hours, the Taal Volcano Network recorded three hundred and two (302) volcanic earthquakes, the most ever recorded this year.

The record number of quakes includes one hundred and eighty-four (184) volcanic tremors lasting one ( 1) to twelve (12) minutes and one hundred and eighty (118) low-frequency volcanic earthquakes.

From five meters evaporation or steam, also increased thirty (30) meters, from fumaroles or gas vents that occurred on the Main Crater.

Sulfur dioxide or SO2 flushing of approximately 925 tonnes per day was measured on March 26, 2021. Last measured in Lake Main Crater a high temperature of 71.8 o C on 71.8 – 04 March 2021 and acidity with pH 1.59 on 12 February 2021.

The size of ground deformation of the volcano based on electronic tilt, continuous GPS and InSAR data predicts slow and Continuous swelling of the Taal volcano erupts in January 2020.
Overall, the mentioned bases may indicate a continuous disturbance of magma in the lower part of the volcano.

Under Alert Level three, a minor volcanic eruption may occur.

At present, Taal remains under Alert Level 2 but Philvolcs chief Renato Solidom recently said that “it may or may not explode” even as he let out a warning for the public living near Taal’s lakeshore to be always on ready to flee with their “Go Bags” on any eventuality.

The DOST-PHIVOLCS reminds the audience at Alert Level 2, steam-driven or phreatic eruption, volcanic earthquake, partial ash, and dangerous accumulation of volcanic gas eruption can suddenly occur.

DOST-PHIVOLCS also reminded individuals the TVI is a Permanent Danger Zone or PDZ of Taal Volcano, especially in the way of Main Crater and Daang Castila fissure, and that residence and boating in Lake of Taal are extremely dangerous.
Local governments are encouraged too to continue to examine and strengthen the readiness of the previously evacuated barangays around Lake Taal in case the volcano will have a new eruption.

Civil aviation officials should encourage pilots to avoid flying near the volcano due to flying ash and rolling stones that could cause a sudden volcano eruption.

DOST-PHIVOLCS is closely monitoring the status of Taal Volcano 24/7 and is ready to immediately inform all authorities of any changes.

Morning of Thursday, 25 March 2021, the Philvolcs reported around 300 volcanic earthquakes from Taal. (AI|MTVN)
