Change Log
May 16, 2007: Database updated to correct inconsistencies with 2/14/2006 file.
December 11, 2006: Version 7.3 of the flatfile has been posted (dated 2/14/2006). This file includes changes to spectral values, due to the use of only usable periods to define the ground-motion measure GMRotI50. Updates on the metadata were made and several errors were corrected. Several more recent updates (such as Vs30 from USGS and imputation of missing values) are not in this version of the flatfile, but are incorporated into the dataset used by the model developers. These updates will be added to the next version.
April 8, 2006: Google Maps interface version 2.
November 5, 2005: Google Maps interface version 1.
April 27, 2005: Initial public release based on flat file dated 4/22/2005, version 6.
