What if five magnitude 7 earthquakes occur at the same time equal distance away?
This animation uses a gridded sphere is to show a single station recording five equidistant earthquakes. For demonstration, we are assuming that each earthquake is about a magnitude 7 and the seismic waves are traveling through similar material, thus the seismograms are all the same. All the seismologist would know about any of the earthquakes is that they occurred somewhere on the dashed circle in the last frame.
