The U.S. Geological Survey Hawaiian Volcano Observatory may conduct additional flight operations over Kīlauea and Mauna Loa to assess volcanic activity and maintain instrumentation. Dates and times are subject to change based on aircraft availability and weather conditions.
Management of the park requires the use of aircraft to monitor and research volcanic activity and conduct search-and-rescue missions. Law enforcement operations support the management of natural and cultural resources, and to maintain backcountry facilities.
