In the past 24-hour period, the Taal Volcano Network recorded ten (10) volcanic earthquakes, including three (3) volcanic tremor events having durations of two (2) to three (3) minutes, six (6) 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 nine hundred (900) meters before drifting east and northeast 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.

In the past 24-hour period, the Taal Volcano Network recorded thirty-six (36) volcanic earthquakes, including thirteen (13) volcanic tremor events having durations of one (1) to ten (10) minutes, twenty (20) low-frequency volcanic earthquake, three (3) hybrid events and low-level background tremor that has persisted since 07 July 2021. Two of the tremor events occurred at 10:18 AM and 10:38 AM were felt at Intensity I in Pira-piraso, Taal Volcano Island, the earlier event reportedly accompanied by a rumbling sound. High levels of volcanic sulfur dioxide or SO2 gas emissions and steam-rich plumes that rose one thousand two hundred (1200) meters before drifting east and northeast were generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 3,780 tonnes/day on 19 July 2021.

In the past 24-hour period, the Taal Volcano Network recorded eighty-six (86) volcanic earthquakes, including eighty-four (84) volcanic tremor events having durations of one (1) to thirty-four (34) minutes, one (1) low-frequency volcanic earthquake, 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 two thousand one hundred (2,100) meters before drifting northeast was generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 5,466 tonnes/day on 17 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 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.
