Land-use planning in Aotearoa New Zealand is supported by reliable forecasts of how local landforms can affect ground-shaking and increase the risk of landslides.
We know that the shape and nature of local landforms can affect the amount of ground shaking in an earthquake, which in turn can trigger landslides. But our understanding of these factors has been limited by the short history of observed earthquake activity in Aotearoa New Zealand, and by the incomplete evidence in the geological record.
We aim to apply the synthetic earthquake catalogue developed in the Fault Model Construction project team to improve hazard forecasting by understanding how local landforms can increase ground shaking and the risk of landslides.
To achieve this, we are:
The research team will work closely with researchers in the Earthquake Induced Landslides Endeavour research programme. Our goal is to improve Aotearoa New Zealand’s resilience to earthquakes by improving our understanding and forecasting of the factors that affect the amount of ground shaking and cause landslides.
Researchers have used earthquake cycle simulators to overcome many of the challenges posed by limited modern observations of large earthquakes.
