What is Vog?

Vog is volcanic fog. It is similar to smog in that it is dirty with particles that are not in typical fog.

Vog is formed when gases from the erupting volcano get into the air, mix with sunlight, oxygen and moisture.

Like smog, vog is not healthy for humans, plants or animals. Many people living near Kilaeau, experience headaches and respitory issues from vog.

Visitors on our tours will see and breath vog, but we rarely have visitors who complain of health issues as a result. Generally, complaints come more often from prolonged exposure by those living near the volcano.

Nevertheless, we encourage all visitors to pay attention to their bodies and take the following precautions:

  • Drink lots of fluids
  • Don’t overexert
  • Don’t smoke

Does vog smell like sulfer? A little bit.
