In the past 24-hour period, the Taal Volcano Network recorded eighty-six (86) volcanic earthquakes, including thirty-one (31) volcanic tremor events having durations of two (2) to five (5) minutes, forty-eight (48) low-frequency volcanic earthquakes, seven (7) hybrid event and low-level background tremor that has persisted since 07 July 2021. Activity at the Main Crater consisted of weak emission of steam-laden plumes from fumarolic vents that rose five (5) meters. Sulfur dioxide (SO2) emission averaged 4,948 tonnes/day on 03 August 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.
