Abstract

Four shocks with epicenters in the region of the northern end of the Peninsular Range of Southern California were studied. Travel times of numerous phases of these four shocks were measured from seismograph records of stations at Pasadena, Mount Wilson, Riverside, La Jolla, Santa Barbara, Tinemaha and Haiwee, in Southern California.

The velocities of propagation of eight principal phases were determined. Thicknesses of three layers above a depth of about 40 k.m. in the earth's crust were calculated.
