PHIVOLCS TAAL Volcano Bulletin 26 July 2021 8:00 AM
Format
In the past 24-hour period, the Taal Volcano Network recorded eight (8) volcanic earthquakes, including four (4) volcanic tremor events having durations of one (1) to three (3) 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 hundred fifty (150) meters before drifting to the northeast and north-northeast were generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 4,553 tonnes/day on 23 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.
