PHIVOLCS TAAL Volcano Bulletin 12 July 2021 8:00 AM
Format
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.

In the past 24-hour period, the Taal Volcano Network recorded seventy-four (74) volcanic earthquakes, including thirteen (13) low frequency volcanic earthquakes, sixty-one (61) volcanic tremor events having durations of one (1) to twenty-five (25) 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 (1,000) meters before drifting west-northwest and southwest were generated from the Taal Main Crater.

Metro Manila (CNN Philippines, July 11) Taal Volcano remained restless as state seismologists recorded 74 volcanic earthquakes in the past 24 hours, maintaining Alert level 3 over the volcano in Batangas Province.
In its 8 am bulletin, the Philippine Institute of Volcanology and Seismology said it observed 13 low-frequency volcanic earthquakes and 61 volcanic tremors having durations of one to 25 minutes on Saturday.
High levels of volcanic sulfur dioxide averaging 6,488 tons per day were also observed, it said.
Taal Volcano also emitted steam-rich plumes as high as 1,000 meters from the main crater, Phivolcs said.
Given its volcanic activities, Alert level 3 stays over Taal Volcano.

A steam-driven plume is seen rising from the main crater of Taal Volcano on Saturday, July 10, 2021. The Taal Volcano Network has recorded seven volcanic earthquakes as well as high levels of volcanic sulfur dioxide in the past 24 hours. Alert Level 3 remains. JAMES AGUSTIN Taal Volcano has had seven volcanic earthquakes in the past 24 hours, and Alert Level 3 remains in effect, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said on Saturday. Of this total, two are low-frequency volcanic earthquakes, four are volcanic tremor events lasting one to two minutes, and one low-level background tremor which has persisted since July 7, PHIVOLCS said in its 8 a.m. bulletin.

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.
