| 摘 要： | Introduction According to the Seismograph Network of China, an earthquake of MS=6.8 occurred at10:03:42 on February 24, 2003 in Jiashi county, Xinjiang (39.55°N, 77.15°E) with the focal depthof 25.2 km. The macroseismic epicenter located at the boundary of Bachu and Jiashi counties,Xinjiang Uygur Autonomous Region. 248 persons died and 4 853 ones were injured (2 058 ofthem were heavily injured) in the earthquake. 49 656 households (about 205 079 persons) losttheir houses.

| Abstract: | The borehole strain meter at Wushi station recorded obvious anomaly before Jiashi Ms = 6.8 earthquake occurredanomaly, short-imminent anomaly and exponential anomaly appeared 19 months, 56 days, 4 days, and more than 1with obvious alternation of tension and compression. According to the magnitude of strain anomaly, time of exponential anomaly appearance and regional features of recorded anomaly, we could predict the magnitude, occurrence time and potential region to a certain degree. |
