【摘要】 通过对发生在2003年9月27日俄、中、蒙交界Ms≥7.9级和2007年7月20日特克斯Ms≥5.9级地震前后,乌鲁木齐形变台站垂直形变资料异常特征的分析和研究认为,乌鲁木齐形变台站的前兆观测资料具有较好的映震能力,对乌鲁木齐周边及北天山中西部地区5～6级以上地震有较好的震前反应,前兆信息明显。地震前后形变形态表现为低值异常—恢复—突跳—发震的特征。更多还原

【Abstract】 It is analyzed the anomalous characteristics of vertical deformation data recorded by Urumqi deformation stations before and after the Ms≥7.9 earthquake in Russia,China and Inner Mongolia on September 27,2003 and the Ms5.9 earthquake in Turks on July 20,2007,and the results show that the deformation data have good reflecting earthquake ability for earthquakes with Ms5~6 in nearby Urumqi and in middle-west of north Tianshan.The deformation characteristics appeared as low-value anomaly-normal-abrupt anomaly-earthquake occurrence.更多还原
