Title: ANALYSIS OF THE SEISMICITY ANOMALIES BEFORE SHIHEZI EARTHQUAKE WITH M_s5. 4
Abstract: The anomaly procedure of the seismicity image and seismological parameter are analyzed on the North Tianshan seismic zone before the Shihezi earthquake with Ms5. 4 occurred on Feb. 14,2003. The earthquake with Ms5. 4 occurred in an empty segment of the seismicity centralized region of Ms4. 0 earthquakes in 2002,on North Tianshan Mountain. 12 items of seismicity in temporal proceeding have some medium-term or short-term anomalies before the earthquake. 3 items of seismic wave parameters appeared some short-term anomalies. Seismic window of Urumqi appeared some anomalies of exceeding warning level in three months before the earthquake. And the activity of earthquakes and seismic swarm is marked in the epicenter around areas about 10 days before the earthquake.
