Despite the decline in seismic activity, Taal continued to emit sulfur dioxide (SO₂), with Phivolcs measuring 107 metric tons during the latest 24-hour monitoring period. The agency classified the emission as weak.
The SO₂ emission level was considerably lower than the 422 metric tons recorded daily from Aug. 5 to 14.
No upwelling of hot volcanic fluids was observed in the Main Crater Lake on Taal Volcano Island, locally known as “Pulo,” and no volcanic smog, or “vog,” was detected during the monitoring period.
Taal Volcano remains under Alert Level 1, indicating low-level volcanic unrest./coa
