Earthquakes and Waves

3. that fracture in the earth along which blocks of crust move relative to each other causing earthquakes
5. a scale that reports the amount of energy released by an earthquake
8. the energy of the wave
11. a body wave that does not penetrate the earths core
14. the distance a seismic station is from the epicenter of the earthquake
15. a wave in which the particles move parallel to the direction of wave energy
16. A sea wave that is created when the seafloor slips after and underwater earthquake

1. the part of the earth between the core and the crust
2. an electronic device that is used to record and transmit earthquake data
4. the top of a waveform
6. the tendency of a system to oscillate with greater amplitude at some frequencies than at others
7. the outer most layer of the earth where earthquakes occur
9. a wave in which the particles move up and down, perpendicular to the direction of the wave energy
10. cycles per second
12. the place on the surface of the earth directly above the focus
13. the area of the earth that is unaffected by both P and S waves
