| 摘 要： | 根据哈萨克斯坦萨特地震台、中国新疆乌什地震台的地震资料分别作出单台小地震平均机制解，研究了１９９０年１１月１２日阿拉木图附近的巴依沙隆６．７级地震前后小区域应力场的变化．同时利用乌鲁木齐地震台的资料研究了该区在强震前后小地震平均机制解的变化．研究表明：天山地区强震前单台小地震平均机制解有Ｐ轴转向、初动符号矛盾比下降等征兆反应。对将单台小地震平均机制解用于地震预报等问题进行了讨论．

| Abstract: | Based on the seismic data from Sater,Kazakhstan and Wushi,Xinjiang,China seismic stations,the average mechanism solution of small earthquakes for single station has been studied respectively.Variations on the small regional stress field around Baysalong M 6.7earthquake near Alma-Ata on Nov.12,1990 were analyzed. Meanwhile,the average mechanism solution of small earthquakes happened around strong shock was studied as well upon the Urumqi seismic station's data.It is indicated that before strong earthquakes in Tianshan region,the average mechanism solution of small earthquakes by single station has got some precursory responses,such as P axis diversion,contradiction rate of first motion marks dropping,etc.Several problems of how to apply the average mechanism solution of small earthquakes in single station to earthquake prediction were discussed also. |
