The Philippine Institute of Volcanology and Seismology (Phivolcs) logged a total of 383 earthquakes from Taal Volcano over a 24-hour period on Tuesday, the most for this year.
Phivolcs also observed Taal Volcano letting off 300-meter tall plumes of steam on Tuesday, which may be unusual as the volcano let off plumes only up to five meters in height on Monday.
“In the past 24-hour period (on Tuesday), the Taal Volcano Network recorded 383 volcanic earthquakes, including 238 episodes of volcanic tremor having durations of one to 12 minutes, 143 low frequency volcanic earthquakes, and low-level background tremor that started at 9:05 a.m. on 08 April 2021,” the agency said.
“Upwelling of hot volcanic fluids in the main crater lake occurred yesterday morning and generated 300 meter-tall steam-laden plumes from active fumaroles on the northern side,” Phivolcs added.
Phivolcs is maintaining Alert Level 2 over Taal Volcano, indicating “increased unrest.”
“DoST (Department of Science and Technology)-Phivolcs reminds the public that at Alert Level 2, sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within and around TVI (Taal Volcano Island),” Phivolcs said.
“Local government units are advised to continuously assess and strengthen the preparedness of previously evacuated barangays around Taal Lake in case of renewed unrest,” it added. SOVEREIGNPH
