Yoshihiro Kaneko shows how computer models of seismic waves and the associated tsunami from a plate boundary earthquake allow us to estimate the potential impacts. This work was funded by New Zealand's Natural Hazards Research Platform and public research funding from the Government of New Zealand.

Volcanic mudflows (lahars) are a potential sudden threat to skiers and others on Mount Ruapehu following eruptions from the crater lake. There is a warning system in place that tells you what to do. (Eruption and lahar footage courtesy of Geoff Mackley).

This animation shows the simulations of ground motions and tsunami wave propagation resulting from the 2016 M7.8 Kaikoura (NZ) earthquake. The ground motion simulation incorporates latest information (the location of faults ruptured during the earthquake, GPS and seismometer data, etc) and is an update from the previous one at https://youtu.be/z1HWet9j070 .
