AEM survey over Kīlauea summit

From the eruption-viewing area near Keanakāko‘i crater, within Hawai‘i Volcanoes National Park, the Airborne Electromagnetic and Magnetic (AEM) survey helicopter and hoop were visible within Kīlauea caldera on July 28, 2022. This survey, which is funded by the Additional Supplemental Appropriations for Disaster Relief Act of 2019 (H.R. 2157), is taking place throughout July over unpopulated parts of Kīlauea. Data collected during the survey will inform USGS scientists on the magma, fault, and groundwater structures below the surface of Kīlauea. USGS photo by J. Kauahikaua.
