Abstract: Shallow structure earthquakes are always concurrent with fault activities. Evidence testifies that earthquakes often occurred densely near the place where the faults exist. There is an intimate relationship between earthquakes and active faults. So in analyzing the danger coefficient of earthquakes, it is very important to ascertain the locations and scale of earthquakes that will occur possibly in the future.

Key words: earthquake, fault

摘要： 浅源地震总是伴随断裂活动而发生的，已有资料证实地震确实是在已有断裂面附近密集发生，地震与地表现有的活动断裂带有密切的关系。为进行地震危险性分析，确定未来可能发生地震的地段和强度是极为重要的。
