9410264 Rockwell This research collaboration is to test the hypothesis that geomorphic features offset the same amount formed in the same number of earthquakes, and that features offset different amounts along the same segment of the fault were offset in different numbers of earthquakes. The area of study will be the Garlock Fault in southern California. Previously, these hypotheses were used to estimate the number of earthquakes associated with features offset different amounts along the Garlock fault. However, lessons learned from the 1992 Landers, California earthquake show violations of these hypotheses. A more detailed study of offsets and dating of features along the Garlock fault should provide new evidence relating to the idea of "characteristic earthquakes" which has in the past been a cornerstone of seismic hazard estimation. This research is a component of the National Earthquake Hazard Reduction Program. ***

小行星9410264 这项研究合作是为了验证这样一个假设，即地貌特征抵消了相同数量的地震形成的相同数量，以及特征抵消了不同数量的沿着同一段断层在不同数量的地震中被抵消。 研究区域将是加州南部的加洛克断层。 以前，这些假设被用来估计与沿沿着加洛克断层不同偏移量的特征相关的地震数量。 然而，从1992年加州兰德斯地震中吸取的教训表明这些假设是错误的。 对加尔洛克断层沿着特征的偏移和年代测定进行更详细的研究，应该会为“特征地震”的概念提供新的证据，这种概念在过去一直是地震危险性估计的基石。 这项研究是国家地震减灾计划的一个组成部分。 ***
