The Walker Pass earthquakes and structure of the Southern Sierra Nevada


On March 15, 1946, a strong earthquake occurred in the Walker Pass area of the southern Sierra Nevada. This earthquake and a large foreshock and numerous aftershocks were well registered at Pasadena and its auxiliary stations in southern California. Copies of records at Boulder City and Pierce Ferry were kindly provided by the U. S. Coast and Geodetic Survey. Mr. S. T. Martner and Mr. F. E. Lehner operated the portable seismometer to record aftershocks at two localities: station No. 1, near Isabella, at 35° 39' 31" N, 118° 25' 45" W, and station No. 2, east of Mojave, at 35° 01'.0 N, 118 ° 01'.7 W.
