摘要: 1999年9月23日与2000年10月3日在新疆轮台东北相继发生了M5.1、4.7级地震,两次地震前,北天山地区地下流体都相继出现了不少前兆异常,但两次前兆异常也存在着明显差异。本文对异常形成的机制、异常形成的原因进行了初步分析。Abstract: On Sep.23,1999 and Oct.3,2000,a Ms5.1 and a Ms4.7 earthquake occurred in Luntai of Xinjiang respectively.Before the two events,a lot of precursory anomalies of subsurface fluid appeared in north Tianshan mountations area,but there is clearly difference in the anomalies before the two events.In the paper,the mechanism and cause of the anomalies' development are primarily discussed.
