Taal restive again

Taal Volcano has been observed to be emitting more volcanic sulfur dioxide from its main crater, said the Philippine Institute of Volcanology and Seismology in a 12 August advisory on its website.

Netizens on 11 August took a snapshot of the volcano spewing white smoke.

The Philvolcs advisory said: “A total of 13,572 tonnes/day of volcanic sulfur dioxide or SO2 gas emission from the Taal Main Crater was recorded yesterday (11 August) that produced significant volcanic smog or vog over Taal Caldera.

“Airborne volcanic gas is expected to be drifted to the general east to north-northeast of Taal Volcano Island or TVI based on air parcel trajectory data from PAGASA.

“SO2 flux since 15 July 2022 has averaged ­­­­7,818 tonnes/day, an increase from the average of 1,289 tonnes/day between May and mid-July 2022.

“Since the beginning of August 2022, there has been an increase in degassing activity in the form of visible upwelling of volcanic fluids in the Main Crater Lake and emission of voluminous steam-rich plumes that last night rose 2,800 meters above TVI.”
