Augmented NZ earthquake catalogue used in NZ NSHM 2022
For use in several inputs to the 2022 update to the New Zealand National Seismic Hazard Model (NZ NSHM 2022), we develop an augmented New Zealand earthquake catalogue in which we import higher-quality earthquake depths and depth uncertainties, focal mechanisms, and some locations and magnitudes from several relocated and global catalogues. These are imported into and combined with the Christophersen et al. (2022) NSHM earthquake catalogue (link further down in Other resources), in which the local magnitudes that comprise most of the GeoNet catalogue were brought into alignment with moment magnitude in a way that ensures consistency through time. Next, we use event depths, focal mechanisms, 3D models of the Hikurangi and Puysegur subduction interfaces, and relative plate motion directions to classify earthquakes as upper-plate, interface or intraslab, with special treatment of the remaining lower-quality event depths in the augmented catalogue.
