| 摘 要： | 利用1988～2005年18年间全国会商会所提出的各类定点前兆异常,研究其与下一年(1989～2006年)大陆地震的对应关系,从414次地震资料的统计中得出,除地下水位和地磁外,其它5种前兆观测手段在有震区的异常比均低于无震区或全大陆的异常比,但各手段综合异常比在有震区要高于无震区。遵照"地震监测能力好的前兆手段,在其监测范围内,有震时应有较高的异常比,无震时应有较低的异常比"的原则,我们认为地磁和地下水位是比较好的前兆观测方法。

| Abstract: | By using various fixed point precursor anomalies advanced by the Meeting of National Seismological Consideration(MNSC)from 1988 to 2006, the relationship between the anomalies in a certain year and the earthquakes occurring in the Chinese mainland in the next year is studied. Based on the analysis of the data from 414 earthquakes, we get the conclusion that geomagnetism and underground water level observations are the fairly good precursor methods. |
