- •
Strong motion records from the Canterbury earthquake sequence are examined.
- •
Perform 1D nonlinear effective stress site response analyses at liquefiable sites.
- •
Surface motions are deconvolved for use as input motions for site response analyses.
- •
Key aspects of recorded motions are generally captured by the analyses.
- •
Observed bias is due to pore water pressure model in analyses and input motions.
