KILAUEA, Big Island (KHNL) - Recent activity at the Kilauea volcano has resulted in some temporary increased levels of sulfur dioxide in the districts of Kau and Puna.
Health officials say the levels occur mainly in the early morning hours between 9:00 a.m. and 10:00 a.m.
On July 24, air monitors in Pahala in the Kau District recorded a spike of sulfur of almost 9 parts per million, which is considered extremely high and Color Code Purple.
Officials say exposure to such elevated levels can pose an immediate health threat to peole who have asthma and other respiratory conditions.
Since levels can change significantly in minutes, officials say it is impossible to forecast the temporary episodes of hazardous air quality.
