Evaluating the Monitoring Capability of the Shanxi Seismic Network Using Different Methods
Based on the earthquake catalog and observation report data recorded by the Shanxi digital seismic network from 2015 to 2019,various methods including the"Probability-based Completeness Magnitude"(PMC)method,Magnitude-Number(M-N)method,Goodness-of-Fit Test(GFT)method,and the Maximum Curvature(MAXC)method are used to evaluate the monitoring capability of the Shanxi seismic network.A comparative analysis is conducted by considering the actual conditions of the Shanxi seis-mic network and the computational principles of different evaluation methods.The results show that apart from the areas confined by certain stations where earthquakes of ML1.0 and below can be detected,the lower limit of monitoring capability for other regions is ML1.5.The"Probability-based Completeness Magnitude"method is more suitable for evaluating the monitoring capability of the Shanxi seismic network.With the official operation of the early warning network,it is recommended that this method be used to re-evaluate the actual monitoring capability of the earthquake early warning network.
