| Abstract: | On March 19,1996, a strong earthquake (M S 6.7) shook the Jiashi Atushi area in Xinjiang. Before the event, the tiltmeter at the Atushi station recorded obvious medium and short term, and impending earthguake anomalies. The direction of medium and short term trending anomaly tilted to the direction deviating from the epicenter, lasting for 13 months; the trending anomaly had a short time of recovery two months before the quake, then began to accelerate; five days before the shock,the anomaly recovered rapidly, companying with the impending earthquake jump of the observational data. The earthquake occurred during the recovery process of the anomaly. |
