The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported 42 volcanic earthquakes in Taal Volcano in the past 24 hours.
The tremors lasted for one to seven minutes, according to the latest PHIVOLCS bulletin on Thursday.
Alert level 2 is still up in the volcano due to its increased unrest.
PHIVOLCS added that the main crater showed weak emission of steam-laden plumes reaching as high as 5 meters being emitted from vents.
“Based on the last measurements taken, the temperature of the lake in the main crater went up to as high as 71.8°C on March 4 and the pH level reached 1.59 on Feb. 12,” the bulletin stated.
“Ground deformation parameters from electronic tilt, continuous GPS and InSAR data analysis indicated a very slow and steady inflation and expansion of the Taal region since after the January 2020 eruption,” PHIVOLCS added. “These parameters may indicate increased magmatic activity at shallow depths beneath the edifice.”
Alert Level 2 also indicates that magmatic activities inside the volcano may or may not lead to an eruption.
While evacuation is not yet recommended, the Taal volcano island was placed as off-limits.
“Local government units are advised to continuously assess previously evacuated barangays around Taal Lake for damages and road accessibilities and to strengthen preparedness, contingency, and communication measures in case of renewed unrest,” PHIVOLCS said.
