Health Advisories
Visit the Current Conditions Website to find out about current conditions and the health advisory level. Short term exposure to high levels of sulfur dioxide (SO2) and particulate matter (PM2.5) can be harmful to human health at Hawai'i Volcanoes NP. These conditions occur naturally as a result of ongoing volcanic activity. USGS and NPS equiptment measures air quality in numerous locations around the park. Data from all of these these locations are used to create the advisory level. Specific information from two monitoring sites is presented below.
