Earthquake rupture modelling and ground motion simulation

Our research focuses on advancing knowledge on the physics and mechanics of large earthquakes and physics-based ground-motion simulation methods. We proactively interact with earthquake engineers, geodesists, tsunami modellers, geologists and other seismologists focusing on improved understanding of NZ’s crustal structure and geology. The New Zealand GeoNet network allows us to examine and validate ground motions at all scales for a wide range of recent earthquakes.
