PHIVOLCS TAAL Volcano Bulletin 15 July 2021 8:00 AM
Format
In the past 24-hour period, the Taal Volcano Network recorded seventeen (17) volcanic earthquakes, including sixteen (16) volcanic tremor events having durations of one (1) to thirty-six (36) minutes, one (1) low frequency volcanic 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 one thousand eight hundred (1,800) meters before drifting southwest were generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 3,755 tonnes/day on 14 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 one hundred seventy-one (171) volcanic earthquakes, including thirteen (13) low frequency volcanic earthquakes, one hundred fifty-seven (157) volcanic tremor events having durations of one (1) to ninety-seven (97) 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 were generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 6,134 tonnes/day on 12 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 12, 2021 8:35am Taal Volcano continued showing unrest, and 185 volcanic earthquakes were recorded in the past 24 hours, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said on Monday. Alert Level 3 (magmatic unrest) is still in effect over the volcano, PHIVOLCS said in its 8 a.m. bulletin. Magma extruding from the Main Crater could drive explosive eruption, it added. Included in the volcanic earthquakes are seven low frequency volcanic earthquakes, 176 volcanic tremor events lasting from one to 16 minutes, and low-level background tremor which has been there since July 7, according to Taal Volcano Network. The volcano also continued degassing, with volcanic sulfur dioxide or SO2 gas emission averaging 6,421 tonnes/day on Sunday.
