This study explores the magnitude-versus-distance sensitivity of the Kansas Geological Survey (KGS) microearthquake network. The ability of each seismograph station to record earthquakes of various magnitudes as a function of epicentral distance is investigated, and a series of magnitude-versus-distance graphs results. The ability of the network to monitor seismic activity in eastern Kansas is excellent to magnitude 1.5 and is sufficient to detect events greater than magnitude 2.3 in western Kansas. Station detection radii for magnitude 1.5 events range from 145 km for the Emporia seismograph station (EMK) to 225 km at Tuttle Creek (TCK); and for a magnitude 2 event, from 245 km at EMK to 385 km at TCK. The sensitivities of the nine seismographs of the network are similar despite their widespread locations across eastern Kansas.
