The magnitude of completeness is a key quantitative index to assess the detectability of regional seismic network. This paper deals with the detectability of the Capital-circle Seismic Network by adopting the probability-based magnitude of completeness (PMC) method which can reveal the detailed spatio-temporal characteristics of regional seismic network detectability. The earthquake data (2002-2009) and station information of China Earthquake Administration (CEA) are chosen for this study. This paper aims to estimate network detectability and discuss the possibility of improving the network detectability according to the spatio-temporal distribution of completeness magnitudes and the simulation results. The results show that the detectability of the Capital-circle Seismic Network is high in most regions, although the detectability in a few regions needs to be enhanced. Simulation results suggest that increasing stations may further enhance the detectability of the seismic network. The related results in this paper may be helpful for the optimization of the Capital-circle Seismic Network in the future.
