Preliminary map of young faults in the United States as a guide to possible fault activity

This map gives an overview of geologically young faults and is intended to help in evaluation of the potential activity of faulting nationally. This map is a progress report. Because of its scale, it cannot be used as an index of specific faults or fault hazards. However, it offers a synopsis, as of 1975, of more extensive data that must be taken into consideration in assessments of hazards from f

Preliminary map showing recency of faulting in coastal south-central California

This map depicts 1) the locations of presently known or inferred faults and 2) what is currently known about the latest movement along each fault. Symbols superposed on the fault traces indicate the location of known late Cenozoic stratigraphic or geomorphic evidence of faulting. A fault is assigned to one of eight geologic ages (shown by letter symbol or date) based on the time of its latest move
