The Taal Volcano, which erupted five years ago with devastating effects on local communities, is once again releasing hazardous smoke, or volcanic smog (vog), causing deep concern among residents.

On August 19, reports confirmed that Taal Volcano has begun emitting dangerous vog, leading to urgent health warnings. The vog has already reached Batangas, Laguna, Cavite, and parts of Metro Manila. In response, affected areas have swiftly suspended classes in both private and public schools to protect students from potential health hazards.

The current volcanic activity is deeply troubling, not only because it may escalate to a volcanic eruption but also because it poses a real threat to residents' health. This alarming situation painfully recalls the catastrophic eruption five years ago, which left a profound impact on the affected communities. Residents of Batangas and Tagaytay vividly remember the weeks when their cities were blanketed in ash and the tragedy of losing 39 lives due to the eruption, which might also have triggered widespread anxiety and fear from the degassing activity of the volcano. 

Moreover, it is important to understand how smog can affect your health. According to PHIVOLCS, volcanic smog contains sulfur dioxide (SO2), which is acidic and can cause irritation to the eyes, throat, and respiratory tract. The impact on health depends on the duration of exposure to inhalation.

Since exposure to volcanic smog poses health risks, it’s important to know how to protect yourself:

• Wear a mask: Always wear a mask when going outside to prevent inhaling smog.
• Avoid going outside: It is best to stay indoors as much as possible.
• Drink water: Staying hydrated is beneficial.
• Seek medical attention in case of emergency: Be alert to any signs of health issues and go to the hospital if necessary.
