Earthquakes

1. travels through solids liquids and gasses
6. waves of energy that travel through Earth
8. sudden return of elasticcally deformed rock
10. point inside the earth where it earthquakes begin
11. measure the strength of earthquakes
14. reverse fault
16. instrament that records seismic waves
17. strike-slip fault
19. point on the surface above the starting point
20. change in the shape of rock from stress
21. states that sections of active faults that have had relaticely few earthquakes are likely to be the sites of strong earthquakes in the future.
22. second-fastest wave

2. areas where few earthquakes occur
3. waves that travels in the interior
4. measure of the strength of an earthquake
5. normal fault
7. the study of earthquakes
9. amount of damage caused by an earthquake
12. the process of making older structures more earthquake resistant
13. instraments located at or near the surface of the earth that record seismic waves
15. a measurement of how likely an area is to have damaging earthquakes in the future
18. waves that travel along the surface
