判断续发性强震的一种能量标志

AN ENERGY NOTATION TO DISTINGUISH SUCCESSIVE STRONG EARTHQUAKES

摘要:

大地震发生以后,几乎无例外地有余震发生。由于历史地震缺失余震的记载,所以早期余震方面的研究很少。近年来由于区域台网建立,加以强震频繁积累了一些余震的记录,因而地震序列活动的研究日渐其多,但过去多偏重于序列活动类型方面的研究,对于-强震序列活动后有无续发性地震的问题研究尚少,本文拟对这一问题进行一些初步探讨。

Abstract:

In the activity of a seismic sequence, there is often a destructive earthquake after the swarm.It is difficult to say that they belong to the same sequence, but it is possible that they are related each other in mechanism.In this paper, we discuss it from the energy idea. It shows that the volume and the area of the aftershock are related to the energy of the major earthquake.when the released energy is only a little part of the strain energy, then the remained energy is corresponding to the forthcoming strong earthquake.
