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 - Sulfur - Dioxide - Emissions - Volcano
Scientists say higher sulfur dioxide emissions recorded at the volcano's summit 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 - Air - Pollution - Vapor
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.
The U.S. Geological Survey said sulfur dioxide emissions from the volcano have more than doubled since the current eruption began.
Kilauea - Summit - Tons - Tons - Gas
Kilauea's summit was belching 15,000 tons (13,607 metric tons) of the gas each day, up from 6,000 tons (5,443 metric tons) daily prior to the May 3 eruption. People living miles from the eruption are paying attention to the amount of noxious fumes pouring out of the volcano because it creates potential for more vog.
WHAT ARE THE HEALTH IMPACTS?
Everyone - Symptoms - Level - Dr - Josh
"Everyone is having symptoms now on some level," said Dr. Josh Green, a state senator and emergency room physician who has been volunteering in communities where lava fissures have opened in neighborhoods.
Symptoms for generally healthy people can include burning eyes, headaches and sore throats. But those with asthma or other respiratory problems can end up hospitalized.
Symptoms - Green
Those who are healthy, physically active and don't smoke can usually tolerate basic symptoms, Green said, adding...
