The U.S. Environmental Protection Agency’s (EPA) Pacific Southwest Region continues to support efforts to analyze public health threats from volcanic gas emissions, including managing technical data and enhancing multi-agency air monitoring of the emissions. EPA’s work is part of the Federal Emergency Management Agency’s (FEMA) federal response to the Kīlauea volcanic eruption on Hawai‘i Island.

EPA has worked with the Hawai‘i Department of Health (DOH) to establish 10 air monitoring station locations and continues to work with DOH and the County of Hawai‘i on identifying additional locations to provide data on sulfur dioxide, hydrogen sulfide, and particulate levels. The Agency will continue to evaluate data collected from the Air Now Network operated by the DOH. EPA has 16 personnel on Hawai‘i Island and one representative working with FEMA operations in Honolulu.
