本文利用山东省及其邻区14个地震的37条等震线拟合山东地区地震烈度衰减公式。
The formula of seismic intensity attenuation fitted by using 37 isoseismal lines of 14 earthquakes in Shandong and near area.
在重新整理烈度、距离等参数的同时，认为取两等震线的中心线比取烈度的外包线更合理。
When reanalyzing the parameters for intensity and distance, it iS considered that taking the central line of the two isoseismic is more reasonable than taking the outer envelop of the intensity.
本文提出了利用等震线测定地震断层面的走向、倾向、倾角和破裂长度等震源参数的宏观方法。
In this paper, a method is proposed such that the strike, dip, dipping direction and fracture length of a fault plane can be determined using of isoseismal lines.
