江宁台地电阻率异常震例的中短期预报回归方程的建立

本文研究了１９８３年以来江宁台３００ｋｍ范围内Ｍｓ＞４．５地震的５０ｋｍ范围内地方小震的地电阻率异常震例的中、短期前兆异常特征，分析统计了异常参量与地震三要素之间的关系，并初步建立起中短期预报回归方程，大体给出江宁台所能监控的不同强度地震的最大范围和一般距离；研究表明江宁地电前兆异常有其自身的特征。充分研究单台单手段的前兆异常对地震综合预报水平的提高是有益的。

ESTABLISHMENT OF REGRESSION EQUATION FOR MEDIUM- AND SHORT-TERM PREDICTION BASED ON SOME EARTHQUAKE CASES IN JIANGNING STATION

In this paper the anomalous characteristics of the earth resistivity in the medium -and short-term prediction before the Ms>4.0 earthquakes since 1983 in the range of 300km and Ms>3.0 earthquake in the range of 50km are studied. The anomalous parameters and their relation to the three elements of the earthquakes are analysed and studied. The regression equation is established for the medium- and short-term pre -diction. Author has provided monitoring capacity of the earth resistivity in relation to the maximum range and the general distance with different magnitude earthquakes. It is helpful to development of the comprehensive earthquake prediction by means of fu -lly studying the precursory anomalies in single method and single station.
