Abstract

In an effort to understand the mechanism of the February 9, 1971, San Fernando earthquake in relation to seismic observations and regional geology, we have gathered information on the occurrence and amount of ground displacement by surface faulting. Most of the field data were obtained within the first 4 days after the earthquake, because we wished to describe the fault features as much as possible in their pristine state. Systematic observations were made only in the area generally east of Sylmar and Olive View Hospital, that is, in the eastern part of the area strongly affected by the earthquake, where manifestations of surface faulting were particularly well developed. While our description of faulting is therefore limited to this area and while there doubtless are fault features that we have missed in the area studied, our results are presented here as a contribution to the general body of knowledge about the earthquake.

We are grateful to the U.S. Geological Survey and to Woodward-Lundgren and Associates for supplying large-scale aerial photographs of the earthquake area, which helped materially in the mapping. We also wish to acknowledge the contributions to the collection of the field data made by the students and associates whose names are cited in the initial footnote. The material available for this report has been significantly improved by the generous exchange of information among many scientists studying the earthquake, whose names cannot be individually acknowledged here.
