  source volume
(1985) and Kisslinger (1986) noticed a seismic quiescence in the subsequent source volume before the 1986 earthquake and attempted to predict it.
      
A generic gravity source moment is an integral, over the source volume, of the product of the density distribution by a polynomia in the Cartesian coordinates of a point belonging to this volume.
      
Thus, it appears that both the details of the precursors and of the main rupture depended critically on the heterogeneous tress distribution in the source volume.
      
This is based on the constraint caused by the Laplace's equation for the magnetic scalar potential; outside of the source volume the signals are spatially band limited.
      
Larger flares by loop-top source volume are thus neither hotter nor denser.

In 1979 an earthquake of magnitude 6 occurred in Liyang County, Jiangshu province. The epicenter was located in the junction of a NE trending active fault, the known Maoshan fault, with a NW trending active fault, the Fangshan-Tiger Mt. fault.In this paper the focal mechanism of the major shock and several aftershocks has been studied and the strike of seismic fracture has been also determined by means of null vector data. The research results indicate that the Liyang earthquake was caused by a right lateral...

In 1979 an earthquake of magnitude 6 occurred in Liyang County, Jiangshu province. The epicenter was located in the junction of a NE trending active fault, the known Maoshan fault, with a NW trending active fault, the Fangshan-Tiger Mt. fault.In this paper the focal mechanism of the major shock and several aftershocks has been studied and the strike of seismic fracture has been also determined by means of null vector data. The research results indicate that the Liyang earthquake was caused by a right lateral strike-slip dislocation with some normal dip-slip component along the east branch of the Maoshan fault belt under the action of the NEE compression stress field.From the observation of aftershocks, it can be suggested that both the source volume of the b-value of this earthquake sequence is rather small. Using Wyss method and Gibowicz empirical formula, we approximately estimated the stress-drop and the seismic moment as well as the apparent stress of the Liyang earthquake. In the mean time, on the basis of the field geological observations we pointed out tentatively that the Liyang earthquake was generated probably by the locked NE Maoshan fault associted with the left lateral shifting of the NW Fangshan-Tiger Mt. active fault. And this seemed to be a reasonable explanation for the recurrence of two destructive earthquakes being occurred there within 5 years.The authors assume that the Liyang earthquake can be regarded to be a low stress-drop event under a high stress background, implying that the south part of the North China fault block has been stepping into a active stage of high stress.

该地震发生在北东向茅山活动断裂与北西向芳山-老虎山活动断裂的交汇部位。本文研究了主震与若干余震的震源机制解,并应用零矢量方法确定了地震破裂面的走向。研究结果表明,该地震是在北东东向挤压应力作用下,沿着茅山断裂带东支发生了右行走滑错动兼有正断层性质的倾滑分量。根据对余震的观测可知,溧阳地震的震源体积与b值均偏小。运用Wyss方法及Gibo Wicz经验公式粗略估算了溧阳地震的应力降、地震矩与视应力。同时,根据野外地质观察指出,该地区之所以在最近五年来重复发生两次破坏性地震,可能与北西向芳山-老虎山断裂带的左行错动引起北东向茅山断裂带闭锁有关。

On the basis of the interlayer discouple model provided in 1979, we further demonstrate the various kinds of discouple forms, which occur between the granite, layer and the basalt layer. These various discouple forms are caused by various tactonical movements such as depression, uplift and differential movement of upper mantle. We also. discuss the influence of the discouple phenomena on the occurrence of great earthquake. We demonstrate the existence of the interlayer discouple phenomena by means of the non-symmetric...

On the basis of the interlayer discouple model provided in 1979, we further demonstrate the various kinds of discouple forms, which occur between the granite, layer and the basalt layer. These various discouple forms are caused by various tactonical movements such as depression, uplift and differential movement of upper mantle. We also. discuss the influence of the discouple phenomena on the occurrence of great earthquake. We demonstrate the existence of the interlayer discouple phenomena by means of the non-symmetric spatial distribution of bigger aftershocks which occurred after the great Haicheng and the Tangshan earthquakes, Those great earthquakes belong to strike slip type, and their dip angles of faults are nearly verticalWe use the discouple phenomena to discuss the gravity adjustment process in a source volume, which occurs immediately after a gerat earthquake. The gravity adjustment process can be used to explain that the trends of the aftershock fault plane are more scattered, the dip. slip displacements of aftershocks are markedly bigger than that of the mainshock, and the aftershocks with dip slipping distribution mainly in the depressed region, which can be observed in the epicentral area and nearby.

本文主要讨论了以下几点: 1.在1979年提出的层间解缚模式的基础上进一步论证了在不同的垂直力作用下(地壳下部作下沉,上升和垂直差异运动)在地壳中部软弱面附近两侧岩层(花岗岩层和玄武岩层)间的层间解缚形式,並讨论了层间解缚发生时对大震发生的影响。2.由海城、唐山这两次平推型大震后较大余震平面分布的不对称性论证了层间解缚现象的客观存在性。3.由海城、龙陵、唐山三次平推型大震后余震机制倾滑分量比主震明显增大,余震断层面走向角度在较大范围内变化以及倾滑型余震在整个下沉区的分布论证了大震发生后震中区岩层下塌至解缚区后所引起的岩石碎块间的重力调整过程。

On the premise of tectonic earthquake,taking the aftershock sequence of the Tonghai Earthquake as an example,this paper suggests that as fora shallow earthquake,using its spatailly distributive features is an attempt at applying aftershock sequence to determine strike,dip,and dip angle of fault plane for a large earthquake,and further to evaluate source volume and focal mechanism as well.Such an attempt,we blieve,will be widely made in actual application as the precision determination of focal parameters is increased.From the view-point of tectonics,the possibly existed multiplity of the Tonghai Earthquake has also been tentatively discussed.

本文从构造地震的前提出发,以通海地震余震序列为例,说明:对于浅源地震,利用余震序列的空间展布特征,确定一次大地震断层面的走向、倾向、倾角,进而估算震源体积及发震机理,是利用余震序列的一种尝试。随着震源测定精度的提高,这方面的利用将会越来越广泛。文中也从构造的角度,对通海地震可能存在多重性的问题,进行了初步讨论。
