PHIVOLCS TAAL Volcano Bulletin 13 July 2021 8:00 AM
Format
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 13, 2021 8:56am Taal Volcano showed signs of continued unrest, with 171 volcanic earthquakes recorded by the Taal Volcano Network in the past 24 hours, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said on Tuesday. Alert Level 3 remains in effect over the volcano, PHIVOLCS said. The quakes included 13 low frequency volcanic earthquakes, 157 volcanic tremor events lasting from one to 97 minutes, and low-level background tremor which has been observed since July 7. Taal Volcano s sulfur dioxide emission is still high, averaging 6,134 tonnes/day on Monday, although this is slightly lower than Sunday s 6,421 tonnes/day. Steam-rich plumes were observed rising from the main crater to as high as 1,500 meters before drifting southwest.

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.

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.
