IN the past 24-hour period, the Taal Volcano Network recorded four (4) volcanic tremor events having durations of two to five minutes and low-level background tremor has persisted since March 29, 2022. Activity at the Main Crater was dominated by upwelling of hot volcanic fluids in its lake which generated plumes 1,500 meters tall that drifted southwest. Sulfur dioxide (SO2) emission averaged 4,474 tonnes/day on 29 March 2022. Temperature highs of 63.7°C were last measured from the Main Crater Lake on 25 February 2022.
Based on ground deformation parameters from electronic tilt, continuous GPS and InSAR monitoring, Taal Volcano Island and the Taal region has begun deflating in October 2021.
The Alert Level 3 (Magmatic Unrest) prevails over Taal Volcano. This means that there is a magmatic intrusion at the Main Crater that may further drive succeeding eruptions. DOST-PHIVOLCS strongly recommends Taal Volcano Island and high-risk barangays of Bilibinwang and Banyaga, Agoncillo and Boso-boso, Gulod and eastern Bugaan East, Laurel, Batangas Province be evacuated due to the possible hazards of pyroclastic density currents and volcanic tsunami should stronger eruptions subsequently occur.
The public is reminded that the entire Taal Volcano Island is a Permanent Danger Zone (PDZ), and entry into the island as well as high-risk barangays of Agoncillo and Laurel must be prohibited. All activities on Taal Lake should not be allowed at this time. DOST PHIVOLCS
