The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded at least 31 volcanic earthquakes from Taal Volcano as of Sunday morning, adding that the volcano also emitted a steam-rich plume that rose as much as 2.5 kilometers.

Also, the National Disaster Risk Reduction and Management Council (NDRRMC) said that 3,141 people belonging to around 788 families from the towns of Agoncillo, Laurel, San Nicolas and Lemery in Batangas have already been evacuated.

“Taal Volcano Network recorded 31 low frequency volcanic earthquakes and low-level background tremor that has persisted since 08 April 2021. High levels of volcanic sulfur dioxide or SO2 gas emissions and steam-rich plumes that rose as much as 2,500 meters high that drifted south-southwest was generated from the Taal Main Crater,” Phivolcs said.

“Sulfur dioxide (SO2) emission averaged 14,699 tonnes/day on 03 July 2021. In addition, vog was observed over Taal Volcano and vicinity,” it added.

The agency also observed ground deformation, which may indicate movement of magma, gas, or other fluids like moving underground.

“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,” Phivolcs said.

The agency is maintaining Alert Level 3 (Magmatic Unrest) over Taal Volcano.“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 well as into the high-risk barangays of Agoncillo and Laurel must be prohibited due to the hazards of pyroclastic density currents and volcanic tsunami should strong eruptions occur,” Phivolcs said.
