This report presents results of recurrence interval derivation and probability of surface rupture detection studies undertaken for the New Zealand National Seismic Hazard Model 2022 (NSHM) update. Recurrence intervals are one of numerous inversion constraints that are used to constrain the rate of fault ruptures. Here, we utilise earthquake timings, single-event displacement and slip-rate data from the Paleoseismic Site Database, along with geologic and geodetic slip rates from the New Zealand Community Fault Model v1.0...
