The Philippine Coast Guard (PCG) has started undertaking preemptive evacuation from Taal Volcano Island after the Philippine Institute of Volcanology and Seismology (Phivolcs) recorded increased quakes from the island over a period of past three days starting Saturday.
Phivolcs said tremors from Taal Volcano intensified with 98 recorded over a 24-hour period on Monday, according to Phivolcs.
The PCG also notified residents of the island of the preemptive evacuation, with the coast guard deploying five of its vessels with about 200 residents from Sitio Tabla and Sitio San Isidro targeted.
Phivolcs said that the 98 tremor episodes from Taal on Monday had durations from five to 12 mintues. Phivolcs also observed that “Activity in the main crater consisted of weak emission of white steam-laden plumes from fumaroles that rose five meters high. Temperature highs of 77.1 degrees Centigrade and pH of 1.59 were last measured from the main crater lake on 12 February 2021.”
Phivolcs also reported volcanic quakes from Taal Volcano in the following days: Sunday, six lasting from three to seven minutes; and Saturday, 12 from six to 12 minutes each. Phivolcs recorded no tremors or earthquakes from Taal Volcano on Friday.
With Phivolcs recording numerous tremors or quakes from Taal Volcano, it has maintained Alert 1 over the volcano area.
“Alert Level 1 (Abnormal) is maintained over Taal Volcano. DOST (Department of Science and Technology)-Phivolcs reminds the public that at Alert Level 1, sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within the Taal Volcano Island,” Phivolcs said.
