| 摘 要： | 强震震源周围地电、水化学、水动态、地应力和地形变等５种前兆短临异常 时空演化取决于主要活动构造和强震发震机制；远场异常时空演化与主要活构造有 关，不同活构造上异常时间演化有差异性；在特定年份１ａ尺度地电阻率异常显示异 常高潮期，Ms≥５．０地震能量达到１次以上Ｍｓ７．０强震能量的年份与异常高潮期 同步或滞后１ａ，二者与地球自转加速年份基本对应。根据两方面的研究结果进行了 实际预测检验，在预测区间和预测时间段（０．５ａ或１ａ）内发生强震、中强震１０次，其 中７次地震地点基本准确，３次地震地点较为准确。

| Abstract: | The time-space evolutions of the short-impending anomalies of the five kinds of precursors which include geoelectricity,hydrochemistry, ground water behavior, ground stress and ground de- formaticn around a strong earthquake are depended upon the active master structures and the gen- erating-earthquake mechanism.The evolutions of the far-field abnormalities of the precursors are related to the structures and the abnormalities at different structures have the diversity of evolu- tional time. In some particular years one-year scale anomaly of earth resistivity demonstrates the anomaly fastigiums which are synchronous with the years when energy of 5.0 earthquakes is up to that of a Ms =7.0 earthquake or are delayed one year. The fastigiums and the years are fairly corresponding to the years of the acceleraticn of the earth rotation. According to the research results of the two respects, 12 strong and moderate earthquakes are predicted so that 10 shocks of them occurred in the predicted area and the predicted time interval (a half year or one year time interval) .The sites of seven shocks are basically exactly predicted and those of three shocks are fairly exactly done. |
