摘要
初步总结了乌鲁木齐地区地下流体中等地震源兆的特征。认为中等地震源兆具体表现为震前 1～ 2年 ,多个监测点出现相互配合的前兆异常、或同一测点的绝大多数主测项出现同步性高值异常 ,临震前可能表现出异常过程的转折或反向 ,震后异常由强到弱 ,直至消失。最后对震兆形成的原因进行了初步探讨。
The characteristics of moderate earthquake source precursors in subsurface fluid are summarized in the paper,and they will occur 1～2 years before the event.Their process is turning or diversion before the earthquake,and after the event,it changes from stronger to weaker,to disappear .The most observation data are synchronized high value anomaly.The cause of the precursors is also discussed in the paper.
