Abstract

Recent developments in near-real-time recovery of strong-motion data have been expanded to include new means to disseminate and rapidly utilize the data. The TriNet project, a cooperative project in southern California involving CDMG, Caltech and the USGS, will disseminate earthquake data and information rapidly for use by emergency responders. In another development, the release of strong-motion data by CSMIP will include simple descriptors of the shaking level (Light, Moderate, Strong and Extreme Shaking). These descriptors, designed to be easily understood by the non-specialist, will be complemented by more customary quantitative characterizations (time-history and spectral levels). To make strong-motion data widely available for use in earthquake engineering and engineering seismology, the data will be available for access by any current Web browser at the Internet site http://www.consrv.ca.gov/CGS/smip. All strong-motion data released by CSMIP over the years are or will soon be available at this location. For future significant earthquakes, strong-motion data will also be available rapidly at the site.
