Improving our understanding of sedimentary basins through regional site investigation studies: National Update

Abstract 

Most populated and developed areas in Aotearoa New Zealand have been founded upon a deep, soft sedimentary basins, which increase the seismic hazard due to soil site effects and “basin effects” associated with the entrapment and amplification of seismic waves and the generation of localised surface waves. To improve understanding of these effects, several seismic field testing programmes have been undertaken nationwide, leveraging the experience and capabilities of QuakeCoRE Technology Platform 2. These regional field testing studies utilise different geophysical methods to advance our understanding of the variation in the depth to bedrock and the properties of the soil deposits within each basin. Ultimately this new knowledge will form the basis for the updating of the seismic hazard nationwide and help estimate the shaking intensities for a given earthquake scenario.

This presentation will highlight recent site investigation studies across Aotearoa New Zealand undertaken in collaboration with researchers at many NZ universities, within several sedimentary basins, including the Canterbury, Nelson-Tasman, Blenheim/Wairau, South Dunedin, Wellington, Tauranga, Napier/Hastings, Hauraki Plains, and Waikato sedimentary basins.
