  author={A Mignan and Maximilian J. Werner and S Wiemer and Chunhong Chen and Y.-M. Wu},
Assessing the completeness magnitude Mc of earthquake catalogs is an essential prerequisite for any seismicity analysis. We employ a simple model to computeMc in space based on the proximity to seismic stations in a network.We show that a relationship of the form M c d ad c, with d the distance to the kth nearest seismic station, fits the observations well, k depending on the minimum number of stations being required to trigger an event declaration in a catalog. We then propose a newMc mapping… CONTINUE READING
