July 1, 2009 – we are working on adding multicore computer support to ST-RISK and Hazus based damage functions.
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.
March 26, 2009 – ST-RISK now supports analysis in Taiwan.
January 15, 2009 – work starts supporting the USGS 2008 Seismic Model in ST-RISK.May 1, 2008 – work starts on implementing the USGS 2008 Seismic Model in the ST-RISK hazard computational engine.
April 16, 2008 – ST-RISK now supports Pakistan.
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.
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 Risk Engineering, Inc to provide new seismic models without requiring a new release of the ST-RISK.
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 Risk Engineering 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.
