a compass
For navigation, it shows you what direction you are facing. In drawing, it is a device for drawing circles.
Data from one seismometer can give you the distance to an earthquakes epicentre. When data from two stations is available, by plotting the calculated distances as a circle of known radius around the stations, these two circles will intersect in two places. Add in a third station and all three circles will intersect in the same place which is the epicentre.
