Database of ground motions from tectonic and volcanic events, Hawaii, 2018

This study involves a collection of peak ground motions from the 2018 M6.9 earthquake near Leilani Estates, Hawaii and the seismicity associated with the Kilauea Volcano eruption and summit collapse events. This study was intended to provide instrumental ground motion observations to evaluate ground motion models for use in the USGS Hawaii seismic hazard model. Significant variations in ground motions are observed between shallow tectonic flank collapse earthquakes and Kilauea summit collapse volcanic eruptions.
