| Abstract: | Aheqi Ms5.5 earthquake（41.1°N,78.3°E） occurred on April 19,2009 in Xinjiang Atushi city,Aheqi County.Before this earthquake,the ground tilt data of Aheqi,the tilt data of water pipe and the carbon dioxide of Wushi,the stress of Bachu appeared obviously anomalous.The tendency anomalies appeared distorted yearly changes,short-impending anomalies appeared the accelerated and decelerated vector. |
