MANILA, Philippines — Taal Volcano released a record-high volume of sulfur dioxide emission this year at 11,695 metric tons on Wednesday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.

“A total of 11,695 tonnes/day of volcanic sulfur dioxide or SO2 gas emission from the Taal Main Crater was measured today, 15 November 2023. Visual monitors show continued pronounced upwelling of volcanic fluids in the Main Crater, generating short and weak- to moderate-volume degassing plumes,” Phivolcs said.

The volcano’s previous record-high release of 11,499 metric tons was measured on November 9.

Phivolcs also said that no volcanic smog or vog was observed, but a mild sulfur stench was noted in Banyaga, Agoncillo in Batangas.

“Strong winds drifted the plumes to the southwest. No volcanic smog or vog over Taal Caldera was observed by visual monitors throughout the day. However, a mild sulfur stench was observed in Banyaga, Agoncillo,” it added.

Alert Level 1 is still in effect as of posting time, which means that phreatic explosions, volcanic earthquakes, minor ashfall, and lethal accumulations or expulsions of volcanic gas may occur.
