本文分析了我国14次地震序列的主要地震断层面解和错动性质。结果表明:震群型序列中较强地震的断层面解基本相同,其错动性质或相同或互为共轭错动;双震型序列中两次主震的断层面解明显的不同,其错动性质也有差异,它们的较大余震断层面解分别相似于两次主震的断层面解。在这种情况中,有意义的是第一主震至第二主震中间均有与第二主震断层面解相似的地震发生;主震型序列中早期较强余震断层面解多与主震相同,也有少数较杂乱,总的看来这种一致性劣于震群型序列。最后讨论了不同震型地震断层面解的差异在实用中的意义。
This paper analyzes the main seismic fault solutions and dislocation properties of 14 earthquakes in China. The results show that the fault surface solutions of the strong earthquakes in earthquake swarm sequence are basically the same, and their dislocation properties are the same or conjugate conjugate. The fault plane solutions of the two main shocks in the double-shock series are obviously different, Dislocation properties are also different, and their larger aftershock fault surface solutions are similar to the fault surface solutions of two main shocks respectively. In this case, it is significant that there is an earthquake similar to the fault of the second main shock in the middle of the first main shock to the second main shock; in the main shock series, the strong early aftershock faults are mostly solved The same earthquake, but also a few more clutter, the overall view of this consistency is inferior to the swarm-based sequence. Finally, the significance of the differences between the solutions of the earthquakes in different types of earthquakes in practice is discussed.
