Vog Information

March 21, 2011 at 12:15 am Leave a comment

Vog is primarily a mixture of sulfur dioxide (SO2) gas and sulfate (SO4) aerosol. SO2 (invisible) reacts with oxygen and moisture in the air to produce SO4 aerosol (visible). SO2 is expected to be the main problem in areas near the vent on the big island of Hawai’i.

Here are some online resources with information about vog and vog contitions.

The Vog Measurement and Prediction Project (VMAP) has a number of useful pages:

U.S. Geological Survey Hawai’ian Volcano Observatory.
