Lee, Yajie.

Evaluation of attenuation relations in the southern California region. - 166 p.

Adviser: J. G. Anderson.

Thesis (M.S.)--University of Nevada, Reno, 1997.

Regression for empirical attenuation models, which predicts ground motion characteristics as a function of magnitude and distance, is an essential part os seismic design and seismic hazard analysis. Numerous regressions exist. This study selects six of the most recent ones that were judged likely to be appropriate for the southern California region, and attempts to determine which is most successful in predicting ground motions in this region.

520 $a Regression for empirical attenuation models, which predicts ground motion characteristics as a function of magnitude and distance, is an essential part os seismic design and seismic hazard analysis. Numerous regressions exist. This study selects six of the most recent ones that were judged likely to be appropriate for the southern California region, and attempts to determine which is most successful in predicting ground motions in this region.
520 $a For an empirical regression model, most of the constraints come from empirical observations. However, models that include realistic sources and wave propagation also predict some expected characteristics of the regression models. This study thus considers each of the regressions from both theoretical and empirical points of view.
520 $a Site conditions are known to have important effects on ground motions. Regressions are generally specialized for different categories of site conditions. In regression analysis, measurements of site parameters are often considered to be the major way to reduce the residuals of ground motion predictions. In this study, in collaboration with other researchers in the Southern California Earthquake Center (SCEC), we examine some of the proposed site parameters to determine whether detailed site information can help to improve ground motion predictions in the southern California region. Also we calculate the error contributions from source/path and site. We find that in the southern California region, more detailed site information will yield very little improvement in predictions of peak accelerations. Greater improvement is possible at longer periods.
