Across
  1. 3. Areas where one plate is forced beneath another.
  2. 5. A mountain that opens downward to a reservoir of molten rock underneath the surface of Earth.
  3. 7. A Japanese word for tidal wave or big wave in the port.
  4. 9. The area where the fault occurs.
  5. 12. A type of earthquake that is caused by the injection or withdrawal of magma.
  6. 14. The point on Earth's surface directly above the focus.
  7. 15. The world's largest and strongest earthquake belt.
  8. 16. A sudden and violent shifting of massive plates underneath Earth's surface.
  9. 18. These are the first waves to be recorded in a seismic station.
  10. 20. The scientific study of earthquake and the propagation of elastic waves through Earth.
  11. 23. An earthquake that results from detonation of chemicals or nuclear devices.
  12. 24. Molten rock.
  13. 26. Also caled ground roll, cause rock particles to move upward up, backward, and own in a path that contains direction of the wave travel.
  14. 27. A scientist who studies seismic waves.a
  15. 29. A crack across which the rocks have been offset first.
  16. 31. A type of earthquake that occers when Earth's plate shift around.
  17. 32. Are areas or columns where heat or rocks in the mantle are rising toward Earth's surface.
Down
  1. 1. A fault which the hanging wall moves down relative to the footwall.
  2. 2. Occurs when when matter such as magma circulates within Earth.
  3. 4. Refers to a large wave that moves up and down instead of forward.
  4. 6. A type of earthquake that are located underground and in mines.
  5. 8. The roughness or harshness along the fault.
  6. 10. Processes and phenomena associated with the surfical discharge of molten rock
  7. 11. A fault which two blocks of crust slide past each other.
  8. 13. These waves cause the most damage to buildings and other structures.
  9. 17. Refers to the block of crust above the fault.
  10. 19. Waves that travel below the surface of Earth.
  11. 21. Where the earthquake originates from.
  12. 22. The size of the earthquake.
  13. 25. Also called thrust fault, a fault in which the hanging wall moves up.
  14. 28. Locations on Earth's surface that has experienced active volcanic activites for a long period of time.
  15. 30. Is the block of crust below the fault.
