潮汐应力-应变对某些地震序列的调制触发
|
摘要
对1960年以来中国大陆浅源地震序列与潮汐应变的相关分析表明,某些地区某些地震序列,包括前震序列、前震-主震序列、前震-主震-余震序列和主震-余震序列明显受到潮汐应力-应变的调制触发。如龙陵地震的前震-主震序列,邢台地震的前震-主震-余震序列、唐山地震的主震-余震序列等。这些地震序列受到潮汐力调制触发的特征明显,对地震预测有意义,并作了具体的叙述。同时对地震序列受调制触发的机理作了初步的探讨,指出不同类型地震序列的调制触发特征与孕育系统地质构造,地震震源岩石性质和区域构造应力场方向以及地震破裂机制有关,对地震机理和预测的研究有一定意义。
Analysis on the correlation of the seismic sequences of shallow earthquakes and tidal stress in China′s mainland since 1960 shows that some seismic sequences including seismic sequences of foreshocks,foreshocks-main shocks,foreshocks-main shocks-aftershocks and main shocks-aftershocks,such as the seismic sequences of foreshocks-main shocks of the Longling earthquake,the seismic sequences of foreshocks-main shocks-aftershocks of the Xingtai earthquake and the seismic sequences of main shocks-aftershocks of the Tangshan earthquake etc.,were obviously triggered by tidal stress.The triggering of these earthquakes by tidal stress was quite obvious in characteristics and is of important implication in earthquake prediction.A preliminary discussion on the mechanism of the triggering mechanism could be related with the geological structures of earthquake preparation system,the property of rocks in the focal areas,the orientations of the stress field and the directions of the earthquake ruptures.
