Seismic Hazard Assessment

The expert assessment of regional seismicity and the selection of appropriate site-specific earthquake design parameters are vital components of all large projects located in seismic regions. Knight Piésold recognizes that the primary considerations for every seismic hazard assessment are to fully understand the regional seismicity, tectonics, and ground motion attenuation characteristics. We have extensive experience in providing a full range of seismological services in the following areas:

  • Review of regional seismicity and tectonics
  • Historical seismic data collection and processing
  • Selection of appropriate ground motion attenuation relationships
  • Probabilistic seismic hazard analysis
  • Deterministic seismic hazard analysis
  • Seismic site classification and dynamic response analysis
  • Evaluation of site-specific seismic design parameters
  • Development of design ground-motion time-history records

Knight Piésold is experienced with the use of state-of-the-art seismological software that calculates the probabilistic and deterministic earthquake hazard at a site, and in the application of logic tree methods to account for and quantify the uncertainties inherent with seismic hazard assessment.

We have completed seismic hazard assessments, typically including both probabilistic and deterministic hazard analysis, on numerous mining, power, water resources, and infrastructure projects worldwide.
