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 movement inferred from the age of the youngest formation it displaces or from geomorphic features it formed.
