摘要
对我国开展地电阻率观测以来(1967—1988)得到的全部前兆震例70余例(在相应震级影响范围内)进行了汇总分析,其中7级以上8例,6—7级13例,5—6级16例,2—5级34例。给出了电性前兆量的时空分布特征及电阻率前兆持续时间、异常幅度,分布范围和地震三要素的经验规律。
This Paper collects and analyzes all of more than 70 examples with precursors obtained since the observation of earth resistivity in Chlna(in the period of 1987-1988), among which 8earthquakes are with magnitude more than7, 13 with magnitude 6-7, 16 with magnituue 3-6, 34 with magnitude 2-5, The paper also presents the distribution characteristics of time and space of telluric currence anonalies quantity; duration. anomalous amplitude, distributing range of earth resistivity anomar lies; and the empirical regularity for prediction of the three elements of earthquakes.
