  1. Development and refinement of ground motion simulation methods that enable the generation of acceleration time series for the seismic response analysis of infrastructure.
  2. Development of ‘velocity models’ of the earth’s crust in new regions of New Zealand, or improvements in existing regions.
  3. Develop, validate, and apply models for nonlinear near surface site and topographic response for use in conjunction with ground motion simulation methods.
  4. Utilize ground motion simulations to forecast the severity of ground shaking over spatially-distributed regions in future major New Zealand earthquakes.
  5. Examination of modelling uncertainties in ground motion simulation methods and utilization for probabilistic seismic hazard analysis.
  6. Explore the role of simulated ground motions for use in seismic response analysis of engineering infrastructure, including comparisons with as recorded ground motions and development of procedures for simulated ground motions in infrastructure seismic design guidelines.
