摘要
本文定义了描述中等地震活动增强的三个参量E、T和R,通过对辽宁地区13次ML≥5.0地震的统计分析,分别给出了辽西-辽蒙交界、营-海-岫和辽南及两侧海域地区主震震级对E、T、R的回归方程并与实际震级进行对比分析,结果表明,中等地震活动增强参量E、T、R与未来主震震级间存在一定的定量关系,在震级预测上有一定指导意义。
Three parameters E,T,and R are defined in this paper describing the moderate seismic activityenhancing. Through the statiostical analysis of 13 earthquakes of ML≥5.0 in Liaoning region,we figured out the E,T,R of the regression equation ML of the main shock in such areas:the junction of the western region of Liaoning and Liaoning-Neimeng,the Yingkou-Haicheng-Xiuyan region,the South of Liaoning and the sea areas on its two sides,subsequently,a comparative analysis is conducted with the actual magnitude.The results show there is a certain quantitative relation between the parameters and the magnitude of the following main shock,which can help us to forecast the magnitude on a certain significance.
