摘要
简述了2013年7月22日甘肃岷县漳县MS6.6地震的情况。该地震是1954年以来甘肃省发生的最大地震。本文对这次地震的短临前兆进行了综合论述与讨论,内容包括地震发生日与节气和朔望日的关系、地磁静日低点位移的回顾、低点位移的倍九日期回顾、异年倍七律方法的指标在临震日期预测的回顾、甘肃天水深井电阻率的短期前兆的回顾,最后讨论了综合预测的问题。
This study describes the situational characteristics of the Minxian-Zhangxian MS6.6earthquake that occurred on July 22,2013,in Gansu;this is the strongest earthquake felt in this province since 1954.We also review and discuss the short-term and impending precursors of this earthquake:(1)the relation between the earthquake occurrence date and the solar term and syzygy,(2)the displacement of the geomagnetic low point on a quiet day,(3)the multiplied nine days regularity after low-point displacement,(4)the prediction of the impending earthquake's occurrence day using the"rhythm of multiplied seven days in different years"index,and(5)the short-term precursors of geoelectrical resistivity in a deep well at Tianshui station in Gansu.Finally,we discuss the problem of comprehensive prediction.
