Phivolcs measured 1,186 metric tonnes (MT) of volcanic sulfur dioxide (SO2) gas emission from the Taal Main Crater during the past 24 hours, the state volcanologist said in its bulletin on Thursday, Aug. 22.
The “moderate emission” of steam plumes rose 1,500 meters high before drifting northwest.
The volcano in Batangas province released 5,128 MT tons on Tuesday, Aug. 20, Phivolcs record showed.

Vog is composed of SO2 gas and could irritate the eyes, nose, and throat. People with respiratory conditions and pregnant women are at greater risk.
Taal Volcano remained under alert level 1 (low level of volcanic unrest), according to the state volcanologist.
Phivolcs reminded the public that Taal Volcano continued to be in an “abnormal condition.”
