摘要
分析了通渭温泉水汞的观测资料,对该泉水汞的映震能力做了讨论和分析。分析结果表明,该泉水汞异常与中强地震的对应率很高,主要为中短期趋势性异常,范围主要为甘肃中部地区(祁连山中东段地区),对附近地区的(100km左右)中小地震也有较高的对应率,为单点或多点突跳异常。
The data and prediction efficiency of the mercury in Tongwei hotspring were analyzed and discussed. The results show that the mercury anomalies respond well to the moderate-strong earthquake in the middle areas of the Gansu Province (middle-east areas of Qilian Mountain belts) and show as the mid-term and short-term anomalies. In addition, the mercury anomalies could also respond to the medium-small earthquake in the vicinity less than 100 km away and show single or multi value anomalies.
