Hawaii Volcano: First ‘laze,’ now ‘vog?’

Green’s mom, Natasha Green, who lives on the Kona side of the island, said the vog was particularly bad on Tuesday. “It makes it very hard to breathe,” she said, adding that her other symptoms include coughing and watery and stinging eyes.

She’s had to use an inhaler, which she doesn’t need when there isn’t vog. She’s a former smoker, “so that’s probably part of the problem,” she said.

WHO IS AFFECTED?

Vog can affect areas far from the volcano, including the western side of the Big Island and even other islands.

But lately, trade winds have been blowing most of the vog offshore. The National Weather Service said it expected trade winds to slow this weekend, creating hazardous air quality.

With trade winds, communities where lava fissures have opened and those downwind are the most affected.

Kilauea is erupting on Hawaii’s largest island, so there are plenty of areas that aren’t suffering from the effects of vog.

“My phone’s been ringing off the hook,” said Steven Businger, chairman of the University of Hawaii’s atmospheric sciences department. “A little old lady out of Minnesota wants to know if she should cancel her vacation — that kind of thing.”

He told her not to cancel because the vog was blowing away from her planned destination, the Big Island resort town of Waikoloa.

Businger also runs the Vog Measurement and Prediction Project. The website provides current vog conditions for various sites around the Big Island.

IS THE VOG WORSE NOW?

With an increase in emissions, there’s more vog, said Lisa Young, environmental health specialist for the state health department’s Clean Air Branch.

Bruce Corker, a Kona coffee farmer, has noticed. When he looks down from his farm at Kailua Bay, it’s hard to make out the water because it’s the same gray color as the sky.

“For me, it’s just visual,” he said. “I don’t feel any effects on my lungs. I don’t smell anything.”

Corker, who grew up in Southern California, compares vog to “Los Angeles-like smog.”

WHAT ELSE?

Retired photojournalist Chris Stewart says there’s one good thing about vog: It intensifies the colors of a sunset.

But it depends on how thick the haze is. “Some days it’s thin enough you can see the sun passing through,” he said. “But other days we just go inside because we can’t see it at all.”

Stewart said he’s grateful to be living on the Big island’s west side — away from the volcano.

“I almost feel guilty enjoying our sunsets,” he said.
