根据近年来发震构造地质条件研究的进展，本文探讨了划分潜在震源区主要的地震地质规则，具体包括潜在震源区的识别，它的位置、长度、宽度和震级上限的确定等内容。规则的归纳充分考虑了活动构造性质的差异和资料完备程度的不同。重点讨论了如何利用活断层的性质、倾向和活动特性等资料合理地划分潜在震源区的边界问题。 According to the research progress of seismogenic tectonic conditions in recent years, this paper discusses the main seismic geologic rules for potential hypocenters, including the identification of potential source regions, the determination of their location, length, width and magnitude upper bound. The rule induction fully takes into account the differences in the nature of activities and the completeness of the data. It focuses on how to use the data of the nature, tendency and activity characteristics of active faults to reasonably divide the boundaries of potential source regions.
