摘要
在本文中叙述了地震地电学方法判断地震活动趋势的8条指标:1.电性前兆出现的部位;2.地电年变化背景场;3.地震地电阻率ρs的早期下降变化;4.中期平稳波动变化;5.短期加速下降变化;6.临震快速回返(地震发生)变化;7.电性多参数无量纲前兆;8.Δ·T的对数与M之间的统计关系。
The paper depicted eight criteria to asslss seismicty tendency by using earthquakegeoelectrical method: (1) region of producing geoelectrical precursors, (2) awhual variation of backdrop field of geoelectrical resistivity (ρs), (3) earlly descending variation of ρs (4)medium-term stationary variation of ρs(5) short-term quicken descending variation of ρs(6) imminent quicken return (earthquake occurrence) variation of ρs(7), adimension precursor of geoelectrical multi-paramenter, (8) statistical relation between logarithm of Δ. T and M.
