9614759 Allmendinger This project is designed to compare the rates of deformation over geologic time scales of 105-106 years with the rates of deformation over human time scales of 10o -101 years. The area selected for this study is western Argentina, where growth structures have been actively evolving for the last 5 my. Deformation is also active and will be monitored by GPS over the next 3 years. These data will also be compared to a decadal record of earthquake activity, and aseismic components. The results will also have implications for the episodicity of continental deformation, temporal clustering of continental deformation within a volume, and simultaneous movements of faults at different sampling intervals.
