April 18, 2023 — Kīlauea Seismic Imaging Project Node Deployment in Pauahi Crater

A USGS scientist checks the location of the seismic node being installed within Pauahi Crater, in Hawaiʻi Volcanoes National Park, as part of the Kīlauea Seismic Imaging Project. The Hawaiian Volcano Observatory has a permanent monitoring network of several seismometers at the summit of Kīlauea that detect natural earthquakes, but more seismometers are needed to collect data at a higher resolution for this project. An additional 1,800 small earthquake-detecting devices, called seismic nodes, will be temporarily placed on the surface of Kīlauea’s summit region in the next two months. USGS image by M. Patrick.
