Recent Development in Seismic Hazard Assessment in Australia

Dr Paul Somerville

Outline of the presentation

  • Earthquakes in Australia – more frequent than in most “stable” continents Improved models for describing earthquake occurrence rates in Australia
  • New information about active faults in Australia
  • New ground motion prediction models including response spectrum
  • Effect of shear wave velocity of foundation soil or rock on ground motion level
    • has not been treated rigorously in Australia to date
    • potential for significant changes when properly treated
  • Changes in seismic hazard estimates resulting from these new developments
  • Case histories
  • Future developments and trends

Engineers Australia members participating in AGS technical sessions can record attendance on their personal CPD logs. Members should refer to Engineers Australia CPD policy for details on CPD types, requirements and auditing guidelines.
