Seismic Hazard Assessment

Earthquakes are a major concern in many parts of the world causing significant economic pressure and threat to human life. Although the exact time, location, and magnitude of earthquakes can not be predicted, decades of research have allowed us to analyze their effect on structures and public safety. Seismic hazard assessment is a process that evaluates many scenarios for earthquake nucleation in order to provide possible answers to the effect of earthquakes in an area or on specific facilities. Probabilistic seismic hazard assessment is a critical tool in understanding the likelihood of exceeding specific levels of ground motion within a time frame. 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 historical seismicity, and geological and geodetic information.
• 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
