Shaky Isles: Why NZ's seismic risk has just increased
NZ Herald: 4-Oct-2022
The risk of ground shaking in future earthquakes has doubled in many places, under a newly updated seismic hazard model.
But that doesn't mean our shaky isles have become any shakier, with experts putting the new calculations down to what they've learned from a decade of quakes and new science.
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.
"It's important to note there's a lot of variability here – while there's been no change in some places, in others the shaking hazard could be more than double," said the model's project lead, Dr Matt Gerstenberger of GNS Science.
