Seismic Hazard Assessment

Probabilistic seismic hazard assessment is a critical tool in understanding the likelihood of exceeding specific levels of ground motion in a time window, usually the life span of the structures in question. Seismic hazard models are routinely provided at regional scales. For site specific applications such as dams or nuclear power plants, more detailed assessment of seismic hazard is required. We provide complete assessment of seismic hazard for each level of required precision which includes:

  • Determination of seismic source models based on seismicity and geological information. For high-consequence structures such as tailing facilities or nuclear power plant, paleoseismic investigation is also recommended.
  • Calculation of magnitude-recurrence model parameters for each seismic source
  • Selection of appropriate ground motion prediction equations
  • Calculation of hazard curves for selected points and maps for the region
