Answer

Brief Explanations:

Seismographs record ground - motion data. Geologists use multiple seismograph readings to triangulate the location of an earthquake's epicenter and map the location of the focus. Comparing data from around the world helps build a comprehensive understanding. Measuring the time difference between arrival of different seismic waves (not just surface waves) is important for location and other analyses. One reading is not enough to determine the epicenter.

Answer:

They map the location of an earthquake's focus.
