In the past 24-hour period, the Taal Volcano Network recorded one hundred eighty-five (185) volcanic earthquakes, including seven (7) low frequency volcanic earthquakes, one hundred seventy-six (176) volcanic tremor events having durations of one (1) to sixteen (16) minutes, 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 southwest and west-northwest were generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 6,421 tonnes/day on 11 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.

Updated July 11, 2021 8:38am Taal Volcano in Batangas continued emitting steam-rich plumes and high levels of volcanic sulfur dioxide as Alert Level 3 (magmatic unrest) remains in effect on Sunday, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said. The plumes reached up to 1,000 meters before they drifted west-northwest and southwest from the main crater, PHIVOLCS said. The volcano s sulfur dioxide (SO2) gas emission averaged 6,488 tonnes/day on Saturday. Seventy-four volcanic earthquakes were recorded by the Taal Volcano Network in the past 24 hours. Of this number, 13 are low-frequency volcanic earthquakes, and 61 are volcanic tremor events lasting from one to 25 minutes.

In the past 24-hour period, the Taal Volcano Network recorded seven (7) volcanic earthquakes, including two (2) low frequency volcanic earthquakes, four (4) volcanic tremor events having durations of one (1) to two (2) minutes, 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 generally west was generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 4,149 tonnes/day on 09 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.

A series of five (5) short phreatomagmatic bursts occurred at 06:47 AM, 06:06 PM, 09:21 PM, 09:50 PM yesterday, and 02:59 AM today and produced short, jetted plumes that rose to 200 meters above the Main Crater Lake.
In the past 24-hour period, the Taal Volcano Network recorded fifty-eight (58) volcanic earthquakes, including five (5) explosion-type earthquakes, twenty-four (24) low frequency volcanic earthquakes, twenty-seven (27) volcanic tremor events having durations of one (1) to six (6) minutes, two (2) hybrid 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 northwest was generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 6,095 tonnes/day on 08 July 2021. Based on ground deformation parameters from electronic tilt
