Statistics of Worldwide Earthquake Recurrence Series and the (a)periodicity of Large Events

9404962 Ward这项研究是为了分析世界主要板块边界上7级以上大地震的复发规律。地震重现的规律性是许多地震危险性研究的重要输入。以前对地震复发的许多研究都集中在“特征”、分段破碎的事件上。然而，无论是对分段的定义，还是对“特色”事件的选择，都不是毫不含糊的。通过分析大量的重复序列，建立一套客观的选择标准，系统地量化大地震的规律性。这项研究是国家减少地震灾害计划的一部分。***

9404962 Ward This research is to analyze the regularity of recurrence of large earthquakes (M greater than 7) from major plate boundaries around the world. Regularity of earthquake recurrence is a critical input into many seismic hazard studies. Many of the previous studies of earthquake recurrence have concentrated on "characteristic", segment-breaking events. However, both the definition of segments and the selection of "characteristic" events are not unambiguous. By analyzing a large number of recurrence series and establishing a set of objective selection criteria, the study will quantify systematically the regularity of large earthquakes. This research is a component of the National Earthquake Hazard Reduction Program. ***
