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.

On Wednesday, August 25, 2021, an HVO scientist deployed Global Positioning System (GPS) sites in an area just southwest of Kīlauea caldera. The tripod and attached GPS antenna are centered over a benchmark and data are collected to calculate the vertical and horizontal ground motion at that location. These temporary sites were set up at pre-existing benchmarks to supplement HVO’s continuous GPS stations during the intrusion to the southwest of Kīlauea’s summit caldera. USGS photo taken by S. Conway.
