A swarm of minor earthquakes began on July 29, 1959, near 34° 00′ N, 117° 48′ W. Records at Pasadena show P and S waves reflected from the Moho. A portable instrument recorded some of these at a point about 6 km. from the epicenter. The characteristic false S - P of about one second at short distances was recorded.
