Across
  1. 3. a building mounted on bearings designed to absorb the energy of an earthquake
  2. 9. a scale that rates earthquakes according to their intensity and how much damage they cause
  3. 11. a type of seismic wave that moves the ground up and down or side to side
  4. 13. a type of seismic wave that compresses and expands the ground
  5. 14. a mountain that forms where a normal fault uplifts a block of rock
  6. 16. stress that pushes a mass of rock in opposite directions
  7. 17. a device the records the ground movements ground movements caused by seismic waves as they move through earth
  8. 20. a change in the volume or shape of earths crust
  9. 22. stress that stretches rock so that it becomes thinner in the middle
  10. 24. the point beneath earths surface where rock breaks under stress and causes an earthquake
  11. 25. stress that squeezes rock until it folds or breaks
Down
  1. 1. a scale that rates seismic waves as measured by a particular type of mechanical seismograph
  2. 2. the process by which an earthquakes violent movement suddenly turns loose soil into liquid mud
  3. 4. the point on earths surface directly above an earthquakes focus
  4. 5. the measurement of an earthquakes strength based on seismic waves and movement along faults
  5. 6. a large wave produced by an earthquake on the ocean floer
  6. 7. the shaking that results from the movement of rock beneath earths surface
  7. 8. a large area of flat land elevated high above sea level
  8. 10. the block of rock that forms the upper half of a fault
  9. 12. an earthquake that occurs after a larger earthquake in the same area
  10. 15. a break in earths crust where slabs of rock slip past each other
  11. 18. a vibration that travels through earth carrying the energy released during an earthquake
  12. 19. an upward fold in rock formed by compression of earths crust
  13. 21. a bend in rock that forms where part of earths crust is compressed
  14. 23. a type of fault where the hanging wall slides downward; caused by tension in the crust
  15. 24. the block the forms the lower half of a fault
