Research hazard model for the 2021 update to the National Seismic Hazard Model for Hawaii

A research model (RM) was prepared, which incorporates declustered rate grids that are scaled to account for the total number of earthquakes in the full catalog (with no declustering) using factors shown in Table 1 of Petersen et al. (2021), based on Marzocchi and Taroni (2014). A comparison of the 2021 research model and the 2021 National Seismic Hazard Model for Hawaii was performed by creating difference and ratio maps for a uniform-hazard with a 2% probability of excedance in 50 years for spectral accelerations at 0.2 and 1.0 second periods. The data are for a reference site condition of Vs30 equal to 760 m/s. The maps and gridded data used to make the maps are availble here for download.
