The tidal stress field of a layered spherically symmetric Earth due to the Sun and Moon is used to investigate its relation with earthquake occurrence. For the 70 strong earthquakes occurred during the last 24 years in or near China, we computed the tidal stress in spherical polar co-ordinate at the focus at the time of occurrence. The normal and tangential stress components along the slip direction on the earthquake fault plane are then found by co-ordinate transformation. Coulomb's criterion of shear fracture...

The tidal stress field of a layered spherically symmetric Earth due to the Sun and Moon is used to investigate its relation with earthquake occurrence. For the 70 strong earthquakes occurred during the last 24 years in or near China, we computed the tidal stress in spherical polar co-ordinate at the focus at the time of occurrence. The normal and tangential stress components along the slip direction on the earthquake fault plane are then found by co-ordinate transformation. Coulomb's criterion of shear fracture is used to determine whether these stress components will trigger the earthquakes or not.The results show that among the 70 earthquakes, 43 have had triggering effect and for the 18 events occured in North China 14 of them have had triggering effect. It may be concluded that for shallow strike slip earthquakes there are significant triggering effect, while for oblique slip and dip slip earthquakes tidal stress has very little triggering effect. From 72 events occurred over other parts of the world similar conclusion is obtained.Finally, for the purpose, of earthquake prediction, a way in finding a time interval during which the tidal stress may trigger earthquake on possible faults in North China is suggested.

文中计算了由日、月引潮力在地球内产生的潮汐应力场,研究了潮汐应力对地震的触发作用.采用的地球模型是分为十五层的球对称模型.对于近30年来我国或我国邻近发生的七十次较大的地震,计算了震源处在发震时刻的球坐标系中的潮汐应力.通过坐标变换,得到了发震断层面中的正应力及沿错动矢量方向的剪应力.根据岩石的库仑剪破裂准则来判断潮汐应力对所研究的震例是否具有触发作用.结果表明,在七十个震例中,潮汐应力对其中四十三个有触发作用.对于华北地区的十八个震例,潮汐应力对其中十四个有触发作用.还可看出,对于浅源走滑型地震有较明显的触发作用,而对浅源斜滑及倾滑型地震则没有明显的触发作用.对国外七十二个震例的计算结果得到了类似的结论.最后,对华北地区中任一可能的发震地点,提出一种根据潮汐应力来预测发震的危险时间范围的方法.

The scientific principle directing earthquake prediction in China can be expressed in terms of a model by which respective stages of the anomaly groups are traced for making prediction as guided by the view point of integrity. The importance of macroscopic phenomenological method is fully emphasized in regard to methodology. It is suggested that seismic precursors may be searched by making statistic recognition using seismological, geophysical, crustal defor-mational and geochemical data so as to predict the 3 key elements of a forthcoming event and to solve such sophisticated problems as the seismogenic process, etc. It is also pointed out in the paper that the difficulties in earthquake prediction lie in the understanding of the seismogenesis, the mechanic process of the development of the foci, the formation mechanism of the precursors as well as the determination of the variables dominating the earthquake-impending stage. The tidal force, atmospheric pressure and precipitation, etc in the earthquake-impending stage are regarded as noise factors in common situations, yet such factors may become the modulating forces to trigger earthquakes. All those multiply the complexity of the precursors, and should thus be dealt with extreme caution when filtering out the noises.

中国地震预报的科学思路为整体观指导下的异常群体阶段性追踪预报模式。在方法论方面强调了宏观唯象方法的重要性,认为利用地震学、地球物理、地壳形变和地球化学等资料,采用统计识别的方法来寻找地震前兆、进行三要素预报是解决孕震过程这类复杂系统的较好方法。同时指出,地震成因、震源孕育物理力学过程、前兆成因机制、临震阶段起主宰作用的变量等是地震预报的难关所在。临震阶段潮汐力、气压、降水等这些平时视为干扰因素的变化,可能成为发震的触发调制因素。从而增加了前兆的复杂性,在排除干扰时应特别注意。
