The risk of ground shaking in future earthquakes has doubled in many places, under a newly updated seismic hazard model. The latest estimates under the revised National Seismic Hazard Model (NSHM), released today, show the shaking hazard has grown, on average, by 50 per cent or more in most locations. "For example, if there has been a doubling in hazard in a region with a previously very low estimated hazard, then the updated hazard – though greater – may still be low. "The impact on society includes many additional factors that are not part of the science model - like building aspects and structure design – and the National Seismic Hazard Model doesn't address those." By the Numbers50%: The shaking hazard from future earthquakes has increased by 50 per cent or more across the country, under a just-revised seismic hazard model.
