Best Answer

The waves of earthquakes help us determine information about the interior of the earth. The more geologists know about the interior of the earth, the better they can predict earthquakes and other changes in the formation of the Earth's crust.

Is data about an earthquake from two seismographic stations enough information to locate the epicenter?

From Science Explorer Prentice Hall Earth Science: " Geologists use seismic waves to locate an earthquake's epicenter. Seismic waves travel at different speeds. P waves arrive at a seismograph first, with S waves following close behind. To tell how far the epicenter is from the seismograph, scientists measure the difference between the arrival time of the P waves and S waves. The farther away an earthquake is, the greater the time between arrival of the P waves and the S waves." Did this help?
