河西红外测距场地监测能力初步评估

以布设在祁连山—河西走廊地区的跨断层短基线红外测距观测场地为研究对象,通过对这些红外测距场地的代表性测段所反应的断层性质的分析,对祁连山—河西走廊地区的红外测距场地的监测能力进行初步评估。红外测距短基线的监测对于研究断层活动性质有一定的参考价值,但由于监测周期较长等原因,对于判断某些"异常现象"是否为地震的前兆异常比较难把握,应该进行适当优化,缩短监测周期,从而为预测地震危险性提供更加可靠、有价值的判断依据。

PRELIMINARY EVALUATION OF INFRARED DISTANCE MONITORING CAPACITY IN HEXI CORRIDOR

Taking cross fauh short baseline infrared distance site in Qilian moutain-Hexi corridor as study region, this paper make a preliminary evaluation on monitoring capability of infrared distance according to analysis on fault properties. It＇s hard to judge some anomalies before earthquake be- cause of long monitoring period though there still is significant reference value for research of fault activity. We should optimize and shorten monitoring period in order to provide reliable and valuable judgment basis for earthquake prediction.
