Short summary
The purpose of this research is to evaluate the predictive capability of simplified liquefaction models that can be applied across wide geographical areas for insurance and risk management purposes. Predictions from nine models are compared to observations from the Canterbury earthquake sequence and finds that models based on a previously proposed Liquefaction Potential Index perform the best, whilst the commonly used HAZUS methodology does not perform well.
