震源体积是地震学上很重要的一个问题,对此,前人从地震波、余震分布和大地测量方面进行研究。当应用它去解决地震区划和大地震予报时,上述方法就很难应用,因此,利用宏观资料来研究震源体积就很重要了。本文试图通过烈度分布和等震线的形态特征、地震时伴随产生的地表的地震断裂和垂直位移场,建立相应的震源模型来描述震源体积的形 Source size is a very important issue in seismology, to which previous studies have been conducted on seismic waves, aftershocks and geodesy. The above method is very difficult to apply when it is applied to solve the earthquake zoning and earthquakes. Therefore, it is very important to study the source volume by using macroscopic data. This paper attempts to establish the corresponding hypocenter model to describe the shape of the source volume through the distribution of intensity and the characteristics of the isoseismic line, the earthquake rupture and the vertical displacement field along the earth’s surface.
