Note on the tectonics of Kern County, California, as evidenced by the 1952 earthquakes

A statistical analysis has been made of the mechanisms of the aftershocks of the Kern County, California, earthquake of July 21, 1952. A method the writer developed earlier shows the direction of tectonic motion to be at N32°W, approximately normal to the strike of the White Wolf fault. This is in agreement with Gutenberg's fault-plane solution for the main Kern County earthquake which yielded an overthrust in a northwesterly direction. It therefore appears that the Kern County earthquake and its aftershocks were caused by the same tectonic effects.
