dc.description.abstract An important asset in the development of Earthquake Resilience in Aotearoa New Zealand is the nation-wide network of strong motion stations (SMS) deployed and maintained by GeoNet. Each year, these sensors help to locate and record the ground shaking of the over 15,000 earthquakes near New Zealand, of which about 100 are felt. The SMS network was deployed to provide spatial coverage over the country and include a variety of geologic conditions. However, the ground conditions have not been characterised or the existing data is not suitable for analytical purposes at many of these SMS. Leveraging the capabilities of QuakeCoRE Technology Platform 2, recent site characterisation efforts have targeted 34 SMS sites in the Wellington, Upper & Lower Hutt, Gisborne, Napier/Hastings, Marlborough and Dunedin. Several testing methods were utilised, based upon accessibility and expected ground conditions; these methods included seismic cone penetration testing (SCPT), downhole (DH) seismic testing, active & passive surface wave (SW) testing, and microtremor horizontal-to-vertical spectral ratio (mHVSR) testing. This poster presents the initial results of these site characterisation studies, which may be used to improve unde rstanding of historical ground shaking, strengthen the underlying analyses in the National Seismic Hazard Model (NSHM) update, and support ongoing efforts to validate ground motion simulations.
