Assessment on the Earthquake Monitoring Capacity of the Digital Seismic Network of Shanxi Province

Based on the station distribution of the network and obtained parameters, the analysis of earthquake monitoring capacity of the Digital Seismic Network of Shanxi province, compared with analog one, is made. The ranges that earthquake location can be made quickly by using the Digital Seismic Network of Shanxi Province are evaluated and the maximum earthquake magnitude that the network can determine is discussed. The earthquake monitoring capacities for each of two stages of the Digital Seismic Network of Shanxi Province as the upgrading plan are estimated. The result shows that the number of stations installed in middle and southern part of the Digital Seismic Network of Shanxi is not enough to have a reasonable earthquake monitoring capacity. The earthquake monitoring capacity in the northern part of Shanxi province is [WT6BX]M=1 8, M=2 3[WT6BZ] in the middle part and [WT6BX]M[WT6BZ]=2.5 in the southern part. For the earthquakes occurred within the network, the largest magnitude that can be determined by the Digital Seismic Network of Shanxi Province is [WT6BX]M[WT6BZ]=6 6.
