The San Andreas Fault (SAF) is the primary structure within a system of faults accommodating motion between the North American and Pacific plates. Physical models of faulting and characterizations of seismic hazard are informed by investigations of paleoseismology, slip distribution, and slip rate. The impact of earthquakes on people is due in large part to social vulnerability. This dissertation contributes an analysis about the relationships between earthquake hazard and social vulnerability in Los Angeles, CA and investigations of paleoseismology and fault scarp array complexity on the central SAF. Analysis of fault scarp array geometry and morphology using 0.5 m digital …

New quadrangle-scale geologic mapping of the western part of the Date Creek Mountains (DCM) in west-central Arizona has revealed new insights into the geologic units, structures, and geologic history. Three U-Pb dates also provide surprising new information about the age and spatial relationships of the DCM as well as implications for the tectonics of the area. Paleoproterozoic metamorphic rocks in the central part of the DCM are presumably correlative with the Yavapai schist exposed in other parts of the Arizona Transition Zone. A granite formerly assigned to the Paleoproterozoic was subdivided into megacrystic and fine-grained units and hosts a set …
