本文建立了一个实验室和一个数值模型来探讨沿断层摩擦在地震机制中的作用。实验室模型表明，小的冲击是将势能加载到震源结构中所必需的；储存的势能的很大一部分，但不是全部，后来在向系统加载能量的一段时间结束时，在一次大冲击中释放出来。通过在数值模型中引入黏度，在一次大震之后会发生余震。这两种模型都具有描述主序列冲击统计、余震统计和能量震级等特征。
abstract A laboratory and a numerical model have been constructed to explore the role of friction along a fault as a factor in the earthquake mechanism. The laboratory model demonstrates that small shocks are necessary to the loading of potential energy into the focal structure; a large part, but not all, of the stored potential energy is later released in a major shock, at the end of a period of loading energy into the system. By the introduction of viscosity into the numerical model, aftershocks take place following a major shock. Both models have features which describe the statistics of shocks in the main sequence, the statistics of aftershocks and the energy-magnitude scale, among others.
