GRAVITY CHANGES BEFORE LUHUO Ms5.3 AND QINGCHUAN-WENXIAN Ms5.4 EARTHQUAKES,2011
摘要
Abstract
Dynamic evolution characteristics of the gravity field before Luhuo Afs5. 3 on April 10,2011 and Qingchuan-Wenxian Ms5.4 on November 1,2011 are studied. The result shows that the up-speed up-speed down variations of the gravity field emerged before those earthquakes. The variations of the gravity field formed dense,positive anomaly and closed contours in the place where it is the intersection of Xianshuihe, Longmensan and An' ning-he faults.关键词
