Source Characteristics of Large Historic Earthquakes Along The South American Subduction Zone

这项研究是为了研究南美俯冲带上发生的历史性地震(1906-1960年)；1906年至1960年间发生了11次7.8级以上的地震。这一结果将与南美俯冲带上最近发生的1963年后的地震进行比较。其目的是获得该活动板块边界上俯冲带地震、断层分段和破裂模式的更完整的图景。通过这种方法，可以更好地估计沿该俯冲带和其他俯冲带的地震危险性和地震潜力的约束条件。这项研究是国家减少地震灾害计划的一部分。

This research is to study the historic earthquakes (1906-1960) that have occurred along the South American subduction zone; eleven earthquakes have occurred between 1906 and 1960 with magnitudes greater than 7.8. The results will be compared with recent, post-1963, earthquakes that have occurred along the South American subduction zone. The goal is to obtain a more complete picture of subduction zone earthquakes, fault segmentation and rupture mode along this active plate boundary. By this means, better constraints on the seismic hazards and seismic potential along this and other subduction zones can be estimated. This research is a component of the National Earthquake Hazard Reduction Program.
