APPENDIX B: 1994 SPECTRAL ORDINATE MAPS

The following maps may be viewed, downloaded and printed in GIF and PDF formats.

Figure B1. 1994 contour map of the 5 percent damped, 0.3 second pseudo-acceleration spectral response, expressed in percent of the acceleration of gravity, with a 10-percent probability of exceedance in 50 years. The map values include estimates of variability in the attenuation of spectral acceleration and in fault rupture length. GIF, 73kb; PDF, 2.1Mb

Figure B2. 1994 contour map of the 5 percent damped, 1.0 second pseudo-acceleration spectral response, expressed in percent of the acceleration of gravity, with a 10 percent probability of exceedance in 50 years. The map values include estimates of variability in the attenuation of spectral acceleration and in fault rupture length. GIF, 69kb; PDF, 2.0Mb
