摘要
通过整理和剖析兰聊断裂带中南部及其周边地震重力观测资料,分析研究了兰聊断裂带中南部重力场时空变化及其与地震活动的关系,特别是2003年来兰聊断裂发生的几次ML4级左右地震的前兆特征,研究了强震孕育发生过程重力异常特征及探讨断裂带周边重力特征。
With the help of reorganizing and analyzing the observation materials of the Center and South of Lan-Liao Fault Line, the relationship between space-time change of the gravity field and earthquakes is analyzed, especially the precursor characteristics of several ML4 earthquakes since 2003. The characteristics of gravity anomaly in the strong earthquake process and the gravity features around the fault line are researched.
