The Maui News - On Thursday, April 24, sulfur dioxide levels around the Kilauea eruption sites and Hawai‘i Volcanoes National Park on the Big Island kept the park closed, with SO2 levels peaking at 5 parts per million around the Hawaiian Volcano Observatory facilities. The Maui District Health Office issued a health advisory urging residents with respiratory conditions to take precautions, although the state Department of Health said there was no indication of a significant threat to health. “For the general population, it’s not a problem,” said Health Department spokeswoman Janice Okubo. But the blanket of vog could lead to difficulties for individuals who are already impaired, she said. The health office advisory also included a ban on burning on Maui. Northeast winds normally blow the fumes out to sea, but light winds allowed the gas to hover over the volcano.
