Besides lava and ash, Hawaii volcano is pumping out ‘vog’

Kilauea volcano on Hawaii’s Big Island has had it all over the past three weeks: molten rock shooting toward the sky, lava oozing from the ground and ash clouds rising miles into the air.

You can also add “vog” to the mix.

Scientists say higher sulfur dioxide emissions recorded at the volcano’s vents in recent days are creating the potential for heavier than usual vog, or volcanic smog. So far, trade winds have been mostly blowing the gray haze offshore.

WHAT IS VOG?

Volcanic smog, or air pollution, is created by vapor, carbon dioxide and sulfur dioxide gas released from Kilauea. It reacts in the atmosphere with oxygen, sunlight, moisture and other gases and particles. In a matter of hours or days, it converts to fine particles that scatter sunlight, creating a haze that can be seen downwind of Kilauea, according to The Interagency Vog Dashboard, which is made up of Hawaii, U.S. and international agencies.
