Volcano park in Hawaii remains shut
Hawaii Volcanoes National Park remained closed for a second day Wednesday as officials waited for a change in wind direction to blow away sulfur dioxide belching from Kilauea volcano.
The National Park Service said air conditions were worse than Tuesday, when 2,000 people were evacuated from the park.
“This morning, with it being cool and some warmer air on top of it, it has kind of created a pancake effect, so we have some more of the vog lower down,” Michael Larson, the park’s incident information officer, said Wednesday.
“Vog,” or volcanic fog, is formed when sulfur dioxide gas reacts with sunlight, oxygen, dust particles and water in the air.
Tiny droplets known as sulfate aerosols are created, along with sulfuric acid and other substances.
