MANILA – The Philippine Institute of Volcanology and Seismology (Phivolcs) issued a warning on Friday, June 7, 2024, about potential vog (volcanic smog) hazards following elevated sulfur dioxide (SO2) emissions from Taal Volcano.
On Thursday, Taal Volcano emitted 11,072 tonnes of SO2, exceeding its average annual emission of 8,294 tonnes per day.
Vog, a type of air pollution caused by volcanic gas droplets, can irritate the eyes, throat, and respiratory system. The severity of symptoms depends on the gas concentration and exposure duration.
Phivolcs noted that weather forecasts indicate a potential decrease in wind strength over the coming days, which could lead to SO2 accumulation and vog formation in areas around Taal.
“The advisory focuses on the Taal region, but the actual spread of vog will depend on wind direction,” stated Phivolcs Director Teresito Bacolcol.
Residents in affected areas are advised to limit exposure to vog by avoiding outdoor activities and keeping doors and windows closed to prevent volcanic gas from entering homes.
The public is also encouraged to wear N95 masks, stay hydrated, and seek medical attention if needed.
Taal Volcano is currently at Alert Level 1 (abnormal condition). There is a risk of sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall, and dangerous accumulations or releases of volcanic gases, posing hazards to areas within the Taal Volcano Island (TVI).
Entry into TVI, a designated permanent danger zone, is strictly prohibited.
Local government units are advised to monitor SO2 levels and assess potential impacts on public health.
