Seismic Hazard Analysis

EZ-FRISK™ allows you to quickly perform probabilistic and deterministic seismic hazard analysis by:

Your seismic hazard analysis module license comes with area, fault, and gridded seismic sources needed to analyze ground motion hazard in one region of the world. You can license additional regions at additional cost. The U.S. seismic sources comes with fault and variable seismicity gridded sources defined by the USGS and the CGS (Seismic Hazard Mapping Program, 1996, 2002 and 2008). Our validation of the 2008 model shows our implementation matches within 5% of the USGA code in 89% of the cases we tested. The database covers the continental US, Alaska, and Hawaii. The Canadian seismic sources come with fault and area seismic sources developed by the Geological Survey of Canada for use in creating the 2005 building code.

You can also add additional sources to cover other geographic regions or to perform sensitivity studies using custom Seismic Sources.

The attenuation equation database includes virtually all prominently used attenuation equation forms and includes coefficients for over 160 specific attenuation relationships. You can define your own attenuation equations by providing sets of coefficients for the provided equation forms. Using the attenuation table form, you can implement arbitrary attenuation relationships by providing interpolation data. Learn more...

The seismic hazard analysis batch-processing capability allows you to queue multiple runs for execution. This lets you effectively perform sensitivities and parametric studies or work with multiple site locations without significant manual intervention.

The multi-site gridded analysis module is a separately licensed add-on to the annual seismic hazard analysis license. It performs a hazard analysis on a rectangular grid contained by a polygon, or a selected set of points. It generates tabular results useful for creating seismic hazard maps.
