【摘要】 利用新疆区域多年的流动重力和流动水准资料对新疆呼图壁6.2级地震进行形变分析研究,结果表明:在呼图壁6.2级地震前,呼图壁半年尺度和一年尺度流动重力均由正值区域变为零值线附近;流动水准观测表明,呼图壁附近的2条测线在不同部位同步出现量级较大的形变过程,断层活动有加强趋势。更多还原

【Abstract】 The deformation characteristics with the data of mobile gravity and mobile leveling for many years are studied in Xinjiang. The results show that the Hutubi changed from positive gravity to gravity zero line in all scale before Hutubi Ms6.2 earthquake. According to the analysis of mobile leveling, the two survey lines nearby Hutubi show larger deformation in different parts, and the fault movement rate tends to be strengthened before Hutubi Ms 6.2 earthquake.更多还原
