The macroseismic epicenter is situated in the Nula village of the Kyrghyz Republic, 7km southwest of the Wuqia Yierkeshitan Port in Xinjiang. The epicenter intensity is VIII degrees (outside borders). The areas of intensity VII and VI are 7354km^2 and 1031km^2, respectively. This seismic event is related with movement of the NE-trending Kzikeaerkate fault belt. Buildings in the earthquake-stricken area were damaged or affected to a certain extent by this earthquake, accompanied with some phenomena of geological disaster.展开更多

The result shows that the Yutian Ms7.4 earthquake of March 21, 2008, may encourage the Wuqia Ms6.9 earth-quake of October 5, 2008, and the Yutian Ms7.4 earthquake and Wuqia Ms6.9 earthquake may change the seismicity state in the central segment of Tianshan Mountain, Kalpin block and Kashi-Wuqia joint region, and encourage the subsequent Ms≥3 earthquakes.展开更多
