Recent earthquakes near Whittier, California


This paper deals with recent earthquakes noted in a small area near and to the south of Whittier, California, culminating in a shock at 8:46 a.m., P.S.T., on July 8, 1929, which just barely attained destructive intensity. Since the establishment of the Seismological Laboratory and the first group of auxiliary stations of the coordinated network in southern California, installed in 1926 and 1927, earthquakes emanating from this district have been registered as follows: a sharp shock at 11:14 a.m., P.S.T., on October 8, 1927; a swarm of small shocks on December 30 and 31, 1928; and a group in May, 1929. Also, following the main shock, many aftershocks occurred within a few hours, and since then shocks have continued to occur, at increasingly long and irregular intervals, down to the time of writing.
