April 17, 2023 — Kīlauea Seismic Imaging Project Node Deployment

A Hawaiian Volcano Observatory scientist uses a compass to check the orientation of a seismic node (blue) that was deployed on Kīlauea's summit caldera floor on April 17, 2023. The station is one of 1,800 that will collect data for the next two months. The data will be analyzed to outline where the base of Kīlauea contacts the underlying ocean floor, the location of major faults and fault blocks, where bodies of magma are stored beneath the surface of Kīlauea, and how those bodies connect to the rift zones.
