Volcano Watch: Deep electrical studies of Kilauea complete the circuit in 2023

  • A. Ellis/USGS photo HVO staff and collaborators install temporary instruments to collect magnetotelluric (MT) data on Kīlauea volcano’s south flank. At each location, electrodes, induction-coil magnetometers, and data loggers are deployed for 1–2 days. This photo shows a magnetometer being prepared for burial in a narrow and shallow trench to minimize wind noise.

This new year is the final year of Kilauea volcano projects funded by the Additional Supplemental Appropriations for Disaster Relief Act of 2019 (H.R. 2157). This “Volcano Watch” article is about a deep study of subsurface conductivity beneath Kilauea volcano that will reveal its subsurface magmatic plumbing.
