摘要
对2012年3月9日新疆洛浦Ms6.0地震前陆态网络GPS连续跟踪站数据与喀什—伽师2010年7月~2012年3月期间重力复测数据进行计算分析.结果表明:(1)断层两端运动速率不同,为应力积累创造了条件;(2)地震发生前监测区出现区域性的重力异常变化高值区,区域重力场等值线与发震断裂走向平行;震前区域重力场出现增强—减弱—增强过程.
Through calculating and analyzing of GPS continuous observation data and mobile gravity data, the study results are as follows. 1 ) The different movement rate of the the fault ends provides conditions for stress accumulation ;2) The high value zone of gravity anomaly appeared in monitoring area before the earthquake, gravity variation contour line paralleled the fault; and the process of enhancing-weakening-enhancing appeared in regional gravity field before earthquake.
