LUCENA CITY – Taal Volcano in Batangas province emitted voluminous sulfur dioxide (SO2) on Saturday, September 14, amid the reappearance of volcanic smog or “vog.”
The Philippine Institute of Volcanology and Seismology (Phivolcs) reported in its latest bulletin issued on Sunday morning, September 15, that the volcano released a “voluminous emission” of 4,213 metric tons (MT) of SO2 from the volcano’s main crater in the past 24 hours.

State volcanologists also observed the renewed presence of “vog” during the latest observation period after it disappeared on September 9.

Authorities warned the public of the harmful effects of prolonged exposure to volcanic SO, such as irritation of the eyes, throat and respiratory tract, especially among those who have underlying health conditions such as asthma, lung and heart diseases.
Phivolcs again noted an “upwelling of hot volcanic fluids” in the main crater lake.
No earthquake was recorded during this latest monitoring period.
According to Phivolcs, Taal Volcano is still on alert level 1 or a low level of volcanic unrest.
