TAGAYTAY CITY, Cavite – Taal Volcano Network recorded 21 volcanic earthquakes, including 14 volcanic tremor events having durations of two to five minutes, and seven low-frequency volcanic earthquakes based on the Taal Volcano Bulletin released by the Philippine Institute of Volcanology and Seismology (PHIVOLCS), March 23, 2022.
Activity at the Main Crater was dominated by the upwelling of hot volcanic fluids in its lake which generated plumes 900 meters tall that drifted southwest and sulfur dioxide (SO2) emission averaged 6,377 tonnes/day on March 21, 2022.
Temperature highs of 63.7°C were last measured from the Main Crater Lake on February 25, 2022.
Based on ground deformation parameters from electronic tilt, continuous GPS (Global Positioning System), and InSAR (Interferometric Synthetic Aperture Radar) monitoring, Taal Volcano Island and the Taal region has begun deflating in October 2021.
Alert Level 2 (Increased Unrest) prevails over Taal Volcano.
DOST-PHIVOLCS reminds the public that at Alert Level 2, sudden steam or gas-driven explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within and around Taal Volcano Island.
