DSWD DROMIC Report #16 on the Taal Volcano Eruption as of 20 July 2021, 6PM
Format
I. Situation Overview
On 01 July 2021 at 3:37 PM, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) has raised Alert Level 3 over Taal Volcano after a phreatomagmatic eruption from the main crater occurred at 3:16 PM.
As of 20 July 2021 at 8 AM, Alert Level 3 (Magmatic Unrest) now prevails over Taal Volcano. At Alert Level 3, magma extruding from the main crater could drive explosive eruption. The public is reminded that the entire Taal Volcano Island is a Permanent Danger Zone (PDZ), and entry into the island as well as into the high-risk barangays of Agoncillo and Laurel must be prohibited due to the hazards of pyroclastic density currents and volcanic tsunami should strong eruptions occur. All activities on Taal Lake should not be allowed at this time. Communities around the Taal Lake shores are advised to remain vigilant, take precautionary measures against possible airborne ash

In the past 24-hour period, the Taal Volcano Network recorded thirty-six (36) volcanic earthquakes, including thirteen (13) volcanic tremor events having durations of one (1) to ten (10) minutes, twenty (20) low-frequency volcanic earthquake, three (3) hybrid events and low-level background tremor that has persisted since 07 July 2021. Two of the tremor events occurred at 10:18 AM and 10:38 AM were felt at Intensity I in Pira-piraso, Taal Volcano Island, the earlier event reportedly accompanied by a rumbling sound. High levels of volcanic sulfur dioxide or SO2 gas emissions and steam-rich plumes that rose one thousand two hundred (1200) meters before drifting east and northeast were generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 3,780 tonnes/day on 19 July 2021. Based on ground deformation parameters from electronic tilt, continuous GPS and InSAR monitoring, Taal Volcano Island has begun deflati

In the past 24-hour period, the Taal Volcano Network recorded ten (10) volcanic earthquakes, including nine (9) volcanic tremor events having durations of one (1) to six (6) 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 nine hundred (900) meters before drifting northeast was generated from the Taal Main Crater. Sulfur dioxide (SO2) emission averaged 2,441 tonnes/day on 18 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.
