Understanding Vog and Its Effects

The video explains vog, a form of air pollution from volcanoes, composed mainly of sulfur dioxide. Vog forms when volcanic gases react with the atmosphere, creating fine particles that cause visible haze. It poses health risks, including respiratory issues, and can damage the environment. Safety measures include limiting outdoor exposure and avoiding contact with acid rain. Vog can persist for weeks and spread over large areas, affecting distant populations.

What is vog primarily composed of?
