Temporary GPS sites deployed at Kīlauea summit

A temporary Global Positioning System (GPS) site was set up to the south of Kīlauea’s summit caldera to measure vertical and horizontal ground motion during the intrusion last week. A solar panel (bottom center) provides power to the instrument as it collects data. With permission and in coordination with Hawai‘i Volcanoes National Park, this GPS site was deployed in an area that remains close to the public due to safety reasons. The Northeast Rift Zone of Mauna Loa is visible in the background. USGS photo taken by S. Conway on August 25, 2021.
