吉林省前兆台网震例的初步研究

本文清理了吉林省地震前兆台网在省内中等地震，邻区中强以上地震、西太平洋地震带大震前记录到的１４次前兆异常。通过震例统计，筛选出省内前兆映震敏感测点和敏感测项。根据映震范围曲线求出最低映震震级为３．０左右，线性区内最大映震距离为６００￣８００ｋｍ。对５级地震的反映距离为２００￣３００ｋｍ。

PRELIMINARY STUDY OF SEISMIC EXAMPLE MONITORED BY PRECURSORY NETWORK OF STATIONS IN JILIN PROVINCE

In order to resolve the problem of earthquake prediction and to lay down the rational seismic countermeasure, the precursors abnormalities in Jinn province of the Haicheng earthquake, the Tangshan earthquake, within Jilin province the moderate earthquake, etc. are specially discussed by seismological researchers of different degrees, which promotes strongly the development of seismic example studies of Jilin province,and enhances the using value of precursory data .In this paper, the moderate earthquakes in Jilin province, moderate to strong earthquakes in neighboring region and strong earthquakes in the west Pacific Ocean are extensively studied with data of varied precursory subjects, then the earthquake reflecting ability is analyzed and discussed.
