SHARE's contribution to PSHA

SHARE is expected to contribute to new standards in all aspects of Probabilistic Seismic Hazard Assessment:

  • In the definition of engineering requirements
  • In the definition of earthquake sources and activity rates by
    • Assessing of earthquake datasets and magnitude calibration
    • Defining seismogenic sources and geological constraints
    • Building a strain- and slip-rate model
    • Defining Seismic Source Zones (SSZ)
    • Assigning earthquake activity rates
  • In estimating strong ground motion by
    • Defining Ground Motion Prediction Equations (GMPEs)
    • Assessing site effects
    • Providing alternative ground motion paramenters
  • In the assessment of seismic hazard by
    • Working across boundaries
    • Formal elicitation of expert opinions
    • Full treatment of aleatory and epistemic uncertainties
    • Building a sustainable computational infrastructure
  • In engineering applications by
    • Developping a consensus reference European seismic hazard zonation
    • Calculating risk scenarios for selected sites
