When Mt. Kanlaon erupted on June 3, 2024, it sent a massive ash column into the sky, impacting thousands of residents and travelers. With the Philippine Institute of Volcanology and Seismology (Phivolcs) warning of ashfall and a strong sulfuric odor, it’s crucial to know how to protect yourself from the hazards of volcanic smog (vog).
Here’s a guide to help in one’s safety and well-being during such events: What is volcanic smog? Volcanic smog, commonly referred to as vog, forms when sulfur dioxide (SO ) and other volcanic gases interact with oxygen, sunlight, moisture and dust in the atmosphere. This combination creates hazy air pollution that can have severe health impacts, including respiratory distress, eye irritation, sore throat and headaches. How to protect yourself from vog? Stay indoors: One of the most effective ways to reduce exposure to vog is to stay indoors.
Keep windows and doors closed to prevent the smog from entering your home. Avoid strenuous activities: Physical exertion can increase your intake of polluted air, so limit outdoor exercise or strenuous activities. Wear N95 or KN95 masks: These masks are designed to filter out airborne particles.
While they are not perfect for filtering volcanic gases like SO2, they can help reduce the inhalation of ash and other particulates. Use face masks properly: Ensure the mask fits properly to create a good seal around your face. Masks that do not fit well, especially those with beards or mustaches, may not provi.
