New Zealand regions at greatest risk of ground shaking
Some parts of New Zealand are more likely to experience severe earthquakes than others. The colours on this map indicate the likely severity of shaking in different areas – in technical terms, the ground motion which has a 10% chance of occurring within 50 years. These predictions are based on the distribution of active faults, how frequently faults have moved in the past, and the location of historic earthquakes. The zone where the strongest shaking is likely corresponds to the southern part of the Alpine Fault, extending along the Hope Fault into Marlborough.
