GRAVITY ANOMALY IN HAIDAN-ANYANG AREA BEFORE FOUR ML≥4 EARTHQUAKES IN NORTHERN HENAN PROVINCE
Dynamic variation process of mobile gravity before four ML≥4 earthquakes in northern Henan province is analyzed.The result indicates that there is common gravity decreasing process occurred in high gravity value abnormal area before the earthquakes.The earthquakes mostly occur in the area near zero gravity changing isoline.
