ST-RISK™ News

HAZUS® Analysis

March 15, 2010 – ST-RISK™ version 4.5 released, which includes HAZUS damage functions and risk analysis based on those functions.

USGS 2008 Seismic Model

June 11, 2009 – ST-RISK™ version 4.40 released along with new regional data for the continental US. The new regional data uses the USGS 2008 National Seismic Hazard Map seismic model. NEHRP Soil maps now cover the entire continental US, with the new maps generated by using the Wald topography proxy for Vs30 measurements. MMI soil amplifications is now driven by instrumental soil amplification for the entire US.

Taiwan Seismic Model

March 26, 2009 – ST-RISK™ now supports analysis in Taiwan.

USGS 2008 Seismic Model to be Available

May 1, 2008 – work starts on implementing the USGS 2008 Seismic Model in the ST-RISK hazard computational engine.

Pakistan Seismic Model

April 16, 2008 – ST-RISK™ now supports Pakistan.

Next Generation Attenuation Equations

April 4, 2008 – ST-RISK™version 4.30 released along with new regional data models for the Western U.S. The new regional models use MMI estimation from PGV values calculated using Next Generation Attenuation equations. It also features better compatibility with Windows Vista User Account Control, an improved seismic map, and geocoding of Canadian addresses.

More International Seismic Models

March 12, 2007 – ST-RISK™ now supports analysis in South America, Central America, and the Caribbean.This is our first example of supporting new regions using our flexible delivery technology that allows Fugro USA Land, Inc to provide new seismic models without requiring a new release of the ST-RISK.

International Seismic Models

January 8, 2007 – ST-RISK™version 4.20 Released with Improved International Coverage.ST-RISK now supports analysis in Mexico, Europe, the Eastern Mediterranean, and Australia in addition to our previously supported areas of USA and Canada. The program now allows Fugro USA Land to deliver additional regions without requiring reinstallation of the core product. Users now download regional seismic sources and soil conditions as needed for the studies that they are performing. We now have more detailed, comprehensive soil maps for Washington, Oregon, Canada, and all our newly supported regions.
