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.

小行星9614759 该项目旨在比较地质时间尺度为105-106年的变形速率与人类时间尺度为100 - 101年的变形速率。 本研究选择的地区是阿根廷西部，那里的增长结构在过去5年中一直在积极发展。 变形也很活跃，将在未来3年内由GPS监测。 这些数据还将与地震活动的十年记录和地震成分进行比较。 结果也将有大陆变形的幕，大陆变形的时间集群内的体积，并在不同的采样间隔断层的同时运动的影响。
