【摘要】 对滇 9井 (邦纳掌温泉 1号泉 )所观测到的地下流体动态特征进行了研究。结果表明 ,在近源区中强地震前 (距该井 4 0km范围内 ) ,该井地下流体中的水氡、水温、流量等有异常幅度大 ,异常时间同步性好的特征 ,而且异常至发震间隔时间短 ,对短临预报具有参考价值更多还原

【Abstract】 The dynamic variation of underground fluid surveyed through No.9 well (namely the No.1 spring in Bannazhang) in Yunnan Province is studied. The result shows that before the moderate-strong earthquakes in the near-source area (within the range of 40km around the well), the radon, the temperature of the water, the flow quantity have the following three features:①The amplitude of the anomaly is large.②The anomaly is synchronous.③The period between the appearance of anomaly and the occurrence of earthquake is short. So the dynamic features of the underground fluid are significant for the short-impending earthquake prediction.更多还原
