Taal Volcano Network records 95 volcanic earthquakes

In the past 24-hour period, the Taal Volcano Network recorded ninety-five (95) volcanic earthquakes, including sixty-eight (68) volcanic tremor events having durations of one (1) to seventeen (17) minutes, twenty-six (26) low-frequency volcanic earthquakes, one (1) hybrid earthquake and low-level background tremor that has persisted since 07 July 2021.

High levels of volcanic sulfur dioxide or SO2 gas emissions and steam-rich plumes that rose nine hundred (900) meters before drifting to the northeast and east were generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 5,286 tonnes/day on 20 July 2021.

Based on ground deformation parameters from electronic tilt, continuous GPS and InSAR monitoring, Taal Volcano Island has begun deflating in April 2021 while the Taal region continues to undergo very slow extension since 2020.

Alert Level 3 (Magmatic Unrest) now prevails over Taal Volcano. At Alert Level 3, magma extruding from the Main Crater could drive explosive eruption.

The public is reminded that the entire Taal Volcano Island is a Permanent Danger Zone (PDZ), and entry into the island as as into the high-risk barangays of Agoncillo and Laurel must be prohibited due to the hazards of pyroclastic density currents and volcanic should strong eruptions occur.

All activities on Taal Lake should not be allowed at this time. Communities around the Taal Lake shores are advised to remain vigilant, take precautionary measures against possible airborne ash and vog and calmly prepare for possible evacuation should unrest intensify.

Civil aviation authorities must advise pilots to avoid flying over Taal Volcano Island as airborne ash and ballistic fragments from sudden explosions and pyroclastic density currents such as base surges may pose hazards to aircraft.

DOST-PHIVOLCS maintains its close monitoring of Taal Volcano and any new development will be communicated to all concerned stakeholders.

Meanwhile, more than 30 families have been evacuated from Barangay Palanas in Lemery, Batangas, due to the incessant rains brought by the southwest.

According to the town’s Municipal Disaster Risk Reduction and Management Office, the  was not yet high. Still, residents had to be evacuated because the  level was expected to rise due to the continuous downpour.
