Aseismic Creep and Crustal Deformation of Large Normal Faults: Precise Leveling Across Teton Fault, Wyoming

Sylvester, Arthur G.这个项目是对横跨怀俄明州提顿断层的一条精确水平线进行重新测量，以表征一条主要正常断层的地震间活动特征，并将该调查结果与之前1988年、1989年和1991年对该断层的调查结果进行比较，以确定我们在前三次调查中观察到的地震位移是否仍在继续。这项研究的意义在于，它将表明，至少在美国，以前在倾滑断层上未知的地震垂直蠕变，是否正在沿着北美西部的一条主活动断层发生。如果发生这种情况，那么这一结论将影响对沿倾滑断层，特别是沿盆地和山脉断层的沟槽开挖推断的古地震滑动的解释。

9303913 Sylvester, Arthur G. This project is to resurvey a precise level line across the Teton Fault, Wyoming, to characterize the interseismic activity of a major normal fault, to compare the results of that survey with previous surveys of the line in 1988, 1989, and 1991 to determine if aseismic displacement we observed in the three previous surveys is still continuing. The significance of the research is that it will show if aseismic vertical creep, previously unknown on dip slip faults, at least in the United States, is occurring along one of the master, active faults in western North America. If it is occurring, then that conclusion would affect interpretations of paleoseismic slip inferred from trench excavations across dip slip faults, especially along Basin and Range faults.
