Using 3D geological models to create maps of estimated Vs30 and site period
Hill, Matthew; Kaiser, Anna; Wotherspoon, Liam; Manea, Elena (2023-04-19)The 30-m time-averaged shear-wave velocity (Vs30) and the fundamental site period (T0) are useful parameters for understanding site conditions, informing geotechnical studies as well as infrastructure planning. Unfortunately, ... -
Wellington basin amplification: research goals and update from the National Seismic Hazard Model Programme
Kaiser, Anna; Hill, Matt; Wotherspoon, Liam; Bradley, Brendon; Lee, Robin; Roten, Daniel; Bourguignon, Sandra; Pancha, Aasha; Gerstenberger, Matt (2021-04-14)In Wellington, 3D basin amplification effects observed at 1 – 2 second spectral periods were identified as one factor likely to have exacerbated damage to mid-rise structures during the 2016 Mw 7.8 Kaikōura earthquake ...
