Seismic Waves: Seismic waves are the energy released by an earthquake that travel through the Earth and can be detected by seismometers. These waves are used to study the source of an earthquake and how it propagates in the Earth. Richter Scale: The Richter Scale is a numerical scale used to measure the magnitude of an earthquake. The magnitude of an earthquake is measured by the amount of energy released during the event and the scale ranges from 1 to over 8. Fault Line: A fault line is a fracture or break in the Earth's crust that occurs when two plates move in opposite directions. Earthquakes often occur near plates of the Earth's crust that have been pushed together.

The force of an earthquake can be measured in megatons of TNT. The biggest recorded earthquake was in Chile in 1960 with a magnitude of 9.5 on the Richter scale. The United States Geological Survey estimates that nearly 500,000 earthquakes occur each year, yet only 100,000 are felt by people.
