abstract A method for determining lower crustal structure by comparing residuals of distant events, thereby reducing the effect of near-surface structure on seismic waves, has been tested through a straightforward numerical analysis of teleseismic residuals in central California. The results show a general crustal thinning to the west, with a sharp gradient along the San Andreas fault and a uniform crustal thickness between the San Andreas fault and the Calaveras and Hayward faults.
