Data recorded on June 7, 2023, by five seismometers located in Kilauea summit region. The data is shown as spectrograms, which display the energy of seismic events (vertical axis) occurring over time (horizontal axis). Distinct earthquake events are the vertical red spikes in the left side of the plots whereas volcanic tremor is the horizontal red band in the right side of the plots. (courtesy photo/USGS)
