Neotectonics of North America
This volume is part of the Geological Society of America’s Continent-Scale Map (CSM) subset of the Decade of North American Geology (DNAG) publications. Twenty-eight chapters deal with regional discussions of seismicity, stress, and thermal aspects of North America. One chapter provides a regional overview of North American neotectonics, and another deals with late Quaternary isostatic recovery of North America and Greenland. Seventeen chapters discuss seismicity, four discuss regional stress fields, and five discuss regional patterns of the thermal aspect data. These chapters supplement the information portrayed on three 1:5,000,000-scale maps of North America in the DNAG CSM subset: the Seismicity Map, the Stress Map, and the Geothermal Map.

Southern California straddles the boundary between the North American and the Pacific plates. The relative motion between these two plates has been determined from paleomagnetic lineations in the Gulf of California, from global solutions to known slip rates along plate boundaries, from geology, and from geodesy (Minster and Jordan, 1978; Minster and Jordan, 1978; DeMets and others, 1987) to be primarily horizontal at a rate of about 48 mm/yr (DeMets and others, 1987). This results in one of the highest levels of seismicity in the conterminous United States (e.g., Evernden, 1970). In southern California, the deformation is spread over...
