• We compare predictions of network performance to observations made from an earthquake catalogue. We estimate event spectra using Brune modeling and station noise to predict the magnitude of completeness for a network. We compare the predicted magnitude of completeness to an earthquake catalogue for the network. We use the maximum curvature method to assess the magnitude of completeness observed in the catalogue. We find that predicted and observed magnitude of completeness agree reasonably well, with the observed result being consistently lower than the predicted
