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

  • 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.
