Parts of an earthquake |
1)Fault- fracture in the rocks that make up the earth's crust 2)Plates- massive rocks that make out rthe outer layer of the earth's surface 3)Seismic waves- waves that transmit the energy released by an earthquake 4)Focus -below epicenter 5)Epicenter - directly above focus • Magnitude - amount of energy released • Intensity- damage |
