Earthquake near Whittier, California, January 29, 1941

Richter, C. F.

Abstract

Although it alarmed many persons in Pasadena, Whittier, and other neighboring towns, the shock at 5:34 P.M., P.S.T., on January 29, 1941, was only a minor seismic event. Amplitudes recorded on the seismograms give a magnitude of 4.0 on the scale in use at Pasadena. The intensity sporadically reached VI on the Modified Mercalli Scale of 1931, as indicated by scattered instances of displaced furniture, broken dishes, etc. The reports indicate irregular and spotty distribution of intensity, probably associated with unusually short duration of shaking.
