这期专题中的许多论文都涉及地震模拟器及其结果。导致这项工作的项目的目标和历史在这一专题的前言中作了描述。地震模拟器是一种计算机程序，它使用应力传递和摩擦阻力的物理学来描述地震序列。其中一些能够在许多断层上产生长时间的地震历史。它们必须采用各种简化以使计算变得可行。在单个地震中计算的细节数量取决于模拟器。那些能够产生长期历史的人中没有一个包括弹性动力学，但有些人对此进行了近似。然而，在这里重点介绍的任何多断层模拟器中都没有计算地震波。断层通常由许多矩形元素近似，尽管未来使用三角形将允许更准确地表示弯曲的断层表面。本文简要描述了本期《科学研究图书馆》中讨论的所有地震模拟器的共同特征。接下来是四篇论文(Pollitz，2012；Richards-Dinger和Dieterich，2012；Sachs等人)。，2012；Ward，2012)，其中介绍了他们的模拟器的特征，这些特征超出了这种通用描述。使用这些模拟器的结果没有出现在这些论文中，但包含在随后的论文中(Tullis等人。，2012)，比较了在全加州断层模型allcal2上使用这五个模拟器的结果。这个故障模型的详细描述可以在http://scec.usc.edu/research/eqsims/，上找到，我们组用于输入和输出的格式由Barall(2012年)描述。#UCERF…断层几何和滑移率
Many of the papers in this topical issue concern earthquake simulators and their results. The goals and history of the project leading to this work are described in the preface to this topical issue. Earthquake simulators are computer programs that use physics of stress transfer and frictional resistance to describe earthquake sequences. Some are capable of generating long earthquake histories on many faults. They necessarily adopt a variety of simplifications to make computation feasible. The amount of detail computed within individual earthquakes depends on the simulator. None of those capable of generating long histories includes elastodynamics, but some make approximations of it. Nevertheless, seismic waves are not computed in any of the many‐fault simulators focused on here. The faults are typically approximated by many rectangular elements, although the future use of triangles would allow more accurate representation of curved fault surfaces. This paper briefly describes the features that are common to all of the earthquake simulators discussed in this topical issue of SRL . Following it are four papers (Pollitz, 2012; Richards‐Dinger and Dieterich, 2012; Sachs et al. , 2012; Ward, 2012) authored by each of the groups, which present features of their simulator that go beyond this generic description. Results from using these simulators are not presented in those papers but are contained within a subsequent paper (Tullis et al. , 2012) that compares the results of using these five simulators on an all‐California fault model, allcal2. A detailed description of this fault model can be found at http://scec.usc.edu/research/eqsims/, and the formats used for input and output by our group are described by Barall (2012). ### Fault Geometry and Slip Rates UCERF …
