9614651 Smalley 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.

9614651 Smalley 该项目旨在比较 105-106 年地质时间尺度的变形率与 10o -101 年人类时间尺度的变形率。 本研究选择的地区是阿根廷西部，该地区的增长结构在过去五年中一直在积极演变。 变形也处于活跃状态，并将在未来 3 年内通过 GPS 进行监测。 这些数据还将与地震活动和地震成分的十年记录进行比较。 研究结果还将对大陆变形的偶发性、体积内大陆变形的时间聚类以及断层在不同采样间隔的同时运动产生影响。
