Progress Report NGA by I. M. Idriss University of California, Davis April 12, 2005 Richmond, CA

2 PROCESS in basements, dam abutments …etc.
Eliminated all non free-field records such as records in basements, dam abutments …etc. Excluded data from Chi-Chi & its aftershocks Used Geomatrix Categories – A, B, C & D Used average horizontal component Distance ≤ 200 km Style of faulting to be included

3 PROCESS Tried several models with varying degrees of complexities

4 Geomatrix Categories A & B
CURRENT FORM Geomatrix Categories A & B

5 Number of Data Points used
in analyses
