| 摘 要： | 通过对新疆呼图壁新21泉近23年的观测资料系统梳理分析认为,该泉动水位对其300 km范围内的中强地震有较好的短临异常显示,异常特征为"阶跃"型和"脉冲"型,同时当该泉对其100 km范围内4级地震有较强的同震响应时,可能对后续中强地震的发生有一定的前兆指示意义。

| Abstract: | According to observation data of No. 21 spring in Hutubi seismic station since 1990, this paper found the dynamic water level has obvious precursor anomalies such as steps and pulses before moderate earthquakes within 350 kin; while coseismic change with Ms4.0 appeared in No. 21 spring within 100 km, which has indicative significance for subsequent earthquake. |
