利用Bungum和Husebye的方法,分析了地方地震台网的检测能力和可靠性.用标准的计算机定位程序重新测定了地震位置.根据25年的地震记录,分别由震级-频度关系导出的50%、90%和100%的累积检测率估计了检测水平.对台网内地震,相应于100%检测率的震级下限为ML=1.7.用台网内固定的实际震源,研究了台网对震源位置的测定精度.对网内地震,震中测定误差小于4 km.最后讨论了台网连续工作时可能会遇到的影响检测能力的一些问题.
Using the method of Bungum and Husebye, the detection capability and reliability of the local seismographic network are analyzed, and the location of the earthquake is re-measured by a standard computer positioning program.According to the 25-year seismogram, the 50% , 90% and 100% of the cumulative detection rate to estimate the level of detection.On the earthquake in the Taiwan network, corresponding to 100% detection rate of the lower limit of the magnitude of ML = 1.7.Using the station fixed in the actual source, studied the network of the source The precision of the location determination is less than 4 km for the earthquake within the network.Finally, some problems that may be encountered during the continuous operation of the network are discussed.
