本文提出了缺乏地震动加速度记录地区地震动估计的映射法，此法的关键步骤是利用缺乏地震动加速度记录地区Ｂ和已有足够地震动加速度记录地区Ａ的地震烈度衰减关系的映射法，从而求得此两地区的映射地震对，使地震对中的地震所给出的两地区的地震烈度相同。此法的基本假设是：对于Ａ区内的任一地震（ＭＡ，ＲＡ），在Ｂ区内必然存在着一个与之相应的地震（ＭＢ、ＲＢ），使得此一对地震在各自区内引起的地震烈度Ｉ和地震动参数Ｙ相等，即ＩＡ（ＭＡ，ＲＡ）＝ＩＢ（ＭＢ，ＲＢ）和ＹＡ（ＭＡ，ＲＡ）＝ＹＢ（ＭＢ，ＲＢ）。这里，Ｍ和Ｒ分别为地震的震级和表示空间位置的距离。此法的优点是：（１）无需寻求地震动参数与地震烈度、地震活动性参数之间的函数关系，因为这种关系不易求得；（２）可以估计任何地震动参数，只要它是可以根据地震的大小和距离来估计；（３）地区的地震地质背景的影响在烈度衰减关系中得到了考虑。文中给出了例题说明这一方法。
This paper presents a mapping method that lacks the ground motion estimation for earthquake acceleration recording. The key step of this method is to map the attenuation relationship of seismic intensity in region A with the absence of seismic acceleration recording area B and the sufficient acceleration of earthquake acceleration so that The mapping earthquake pairs in these two regions are obtained, so that the earthquake intensity in the two regions given by the earthquake centering is the same. The basic assumption of this method is that for any earthquake (MA, RA) in zone A, there must be an earthquake (MB, RB) corresponding to it in zone B, causing the pair of earthquakes to be caused within their own zone The seismic intensity I is equal to the ground motion parameter Y, ie IA (MA, RA) = IB (MB, RB) and YA (MA, RA) = YB (MB, RB). Here, M and R are respectively the magnitude of the earthquake and the distance representing the spatial location. The advantages of this method are: (1) It is not necessary to seek the functional relationship between the seismic motion parameters and the seismic intensity and seismicity parameters because the relationship is not easy to obtain. (2) Any ground motion parameter can be estimated as long as it can According to the magnitude and distance of the earthquake, it is estimated; (3) The influence of the seismo-geological background of the area is considered in the relation of intensity attenuation. The article gives examples to illustrate this method.
