April 17, 2023 — Kīlauea Seismic Imaging Project Begins
Scientists at the Hawaiian Volcano Observatory deployed caches of seismic node instruments via helicopter around Kīlauea summit yesterday, April 17. Seismic nodes are small earthquake-detecting devices and 1,800 of them are being placed across Kīlauea summit for the next two months as part of the Kīlauea Seismic Imaging Project.
