The New Zealand Community Fault Model (NZ CFM) is a publicly available representation of fault zones that have the potential to produce damaging earthquakes. Compiled through collaborative engagement between earthquake-science experts, this first edition (version 1.0) NZ CFM builds upon previous compilations earthquake-source active models with addition new and modified information. Developed primarily support an update National Seismic Hazard Model, comprises two principal components....
ABSTRACT Large (≥Mw 6.5) earthquakes recorded in active fault systems are commonly clustered space and time, which presents challenges for time-dependent seismic hazard modeling. We investigate the spatial temporal clustering of last 5500 yr on upper-plate faults (Wairarapa, Wellington, Ōhāriu) subduction interface southern Hikurangi margin Aotearoa-New Zealand. recalibrated radiocarbon ages reinterpreted some earthquake timing interpretations from 37 on-land sites (trenches) to produce...
Abstract Site-specific paleoseismic data are key datasets underpinning the parameterization of large (Mw∼7+) earthquakes on faults in seismic hazard models. For New Zealand National Seismic Hazard Model 2022 Revision Project (NZ NSHM 2022), a new database, NZ Paleoseismic Site Database PSDB), was developed that contains (slip rate, earthquake timings, recurrence interval [RI], and single-event displacement [SED]) for crustal (upper plate) active faults. The first edition version 1.0 (v.1.0)...
