Abstract: It is required to answer for reservoir seismic network whether the network's monitoring capability achieves the design goal.According to research results,the use of magnitude-frequency relationship,with the aid of frequency-magnitude diagrams,can answer the above question.In recent years,the method was applied to calculating the monitoring capability of Zipingpu,Pubugou and Wawushan reservoir networks.When studying the background seismicity of specific reservoir,the method can make a better use of regional network catalogues to the study of the background of reservoir seismic activity.When small earthquake cluster occurs in reservoir network area,the possible greatest magnitude of the follow-up earthquake predicted by this method is well consistent with the follow-up practical one.The method can be extensively applied to monitoring and prediction of reservoir-induced and natural earthquake.In characterizing the monitoring capability of a seismic network,the method solves the concern of determining the network's monitoring capability on the aspects of both design goal and measured data.
