New model shows increased earthquake shaking risks

The likelihood of future earthquake shaking hazard is estimated to have increased throughout most of the country, ranging from almost no change to more than doubling in some areas.

These are the latest findings following the 2022 revision of the National Seismic Hazard Model which calculates the likelihood and strength of earthquake shaking that may occur in different parts of Aotearoa New Zealand over specified time periods.

The model, led by GNS Science, is used to estimate risk and help make risk-based decisions.
