9615393 Bevis 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.

该项目旨在比较105-106年地质时间尺度上的变形率与100 -101年人类时间尺度上的变形率。本研究选择的地区是阿根廷西部，在过去的5年中，那里的增长结构一直在积极演变。变形也很活跃，未来3年将由GPS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。这些结果还将对大陆变形的偶然性、大陆变形在一个体积内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。
