Christchurch NZ soils studied using high-resolution near-surface regional Vs model. Depth variability assessed by comparing models of Vs averaged over different depths. 30 m typical Vs profiles used to assess variability in expected seismic response. Site classification maps developed for Christchurch using NZ and international codes. Correlation between Vs5 and observed liquefaction-related damage is examined.
