In the past 24-hour period, the Taal Volcano Network recorded ninety-nine (99) volcanic earthquakes, including ninety (90) volcanic tremor events having durations of one (1) to eleven (11) minutes, nine (9) low frequency volcanic earthquakes, 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 one thousand two hundred (1,200) meters before drifting north and northeast were generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 6,574 tonnes/day on 16 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.

In the past 24-hour period, the Taal Volcano Network recorded twenty-two (22) volcanic earthquakes, including eighteen (18) volcanic tremor events having durations of one (1) to eleven (11) minutes, four (4) low frequency volcanic earthquakes, 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 one thousand five hundred (1,500) meters before drifting southeast and southwest were generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 1,142 tonnes/day on 15 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.

I. Situation Overview
On 13 July 2021 at 8 AM, 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 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. All activities on Taal Lake should not be allowed at this time. Communities around the Taal Lake shores were advised to remain vigilant, take precautionary measures against possible airborne ash and vog and calmly prepare for possible evacuation should unrest intensify.

In the past 24-hour period, the Taal Volcano Network recorded seventeen (17) volcanic earthquakes, including sixteen (16) volcanic tremor events having durations of one (1) to thirty-six (36) minutes, one (1) low frequency volcanic 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 one thousand eight hundred (1,800) meters before drifting southwest were generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 3,755 tonnes/day on 14 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.

Phivolcs said sulfur dioxide emission averaged 3,755 tonnes per day on July 14, while steam-rich plumes that rose 1,800 meters before drifting southwest were generated from the Taal’s main crater.
Based on the latest bulletin, the agency recorded 17 volcanic earthquakes, including 16 volcanic tremor events having durations of one to 36 minutes, one low frequency volcanic earthquake, and low-level background tremors in the past 24 hours.
Phivolcs reminded the public that Taal Volcano remains under Alert Level 3 due to “magmatic unrest.”
“At Alert Level 3, magma extruding from the Main Crater could drive explosive eruption,” it said on Thursday, July 15.
The institute reiterated that the entire Taal Volcano Island is a permanent danger zone, 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
