GRAVITY ANOMALY BEFORE AND AFTER FANXIAN ML4.3 EARTHQUAKE IN HENAN PROVINCE

    摘要
  • 摘要: 分析研究范县地震前后豫鲁测网的重力场与点值变化特征后发现:地震发生在重力场上升过程中,且地震震中位于重力等值线负值区到正值区的过渡带上,重力点值在时间上具有同步性,而震后重力场的下降有可能是新的异常。

     

    Abstract: Through analysis to the gravity anomalies in Hebei and Henan measuring network before and after Fanxian earthquake we found: earthquakes occur in the increasing course of gravity field,and the values at each site have synchrony both in time and magnitude.The drop of gravity after earthquake may be new anomaly.
