These waves are similar to ocean waves, which move throughthe water. Seismic waves, however, move through the ground. Most earthquakes are CAUSED by themovement of large sections of the Earth’s CRUST, called plates. The place where two plates meetis called a fault. FAULTS look like large cracks in the ground. If the two plates move in differentdirections, they build up energy at the fault line. When enough energy builds up, the stress on thefault becomes too great and it RUPTURES.

Man-made earthquakes happen because of nuclear TESTING and mining explosions. The first movement |
