Short-term and impending anomalies of ground tilt before some Ms4.0 and Ms5.0 earthquakes in Xinjiang are analyzed by routine methods. The statistical data such as the period between anomaly initial time and earthquake, the anomaly duration time, the period between anomaly ending and event, the anomalous amplitude and the anomalous shape are summarized. Through analyzing the typical cases the short-term anomalous features of groud tilt before moderate-strong earthquake and strong earthquake in a far distance are presented in the paper. In the short-impending period before event, the number and amplitude of anomalies increase quickly, the anomaly initial time and the predominant period for event occurring are different in different magnitude of events.
