Seismicity catalogs and seismicity zones for the 2021 update of the National Seismic Hazard Models for Hawaii.
The 2021 National Seismic Hazard Model for Hawaii considers the full catalog and several declustered catalogs in calculating earthquake rates and seismic hazard. Events associated with a caldera collapse are treated differently within the model and were separated from the full catalogs. The catalogs are separated into two time periods, pre- and post-1959. The pre-1959 catalog was declustered using both the Reasenberg and nearest neighbor declustering methods. The post-1959 full catalog was split into summit (volcanic) and non-summit events, and those catalogs being separated into shallow (h ≤ 20 km) and deep (h > 20 km). These catalogs were declustered using the Reasenberg and nearest neighbor methods. The declustered, shallow events were further separated into events near the island of Hawai`I (south) and events associated with the islands to the northwest (north). All of these catgalogs are included here and are described in more detail in the paper by Petersen and others (2021). The coordinates that define the summit, caldera, and north/south seismicity zones are also included here.
