April 17, 2023 — Kīlauea Seismic Imaging Project Equipment

A cache of seismic nodes (small earthquake-detecting devices) on Kīlauea caldera floor, which Hawaiian Volcano Observatory scientists deployed on April 17. HVO 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 the Kīlauea Seismic Imaging Project, which will help reveal subsurface structures beneath Kīlauea's summit region. The project is funded by the National Science Foundation (NSF) and the USGS Additional Supplemental Appropriations for Disaster Relief Act of 2019 (H.R. 2157, provided in response to Kīlauea's 2018 lower East Rift Zone eruption and summit collapse).
