1. Seismic sea wave caused by deep sea landslide; incorrectly called "tidal
wave."
-
5. Breaking point of rock, which releases seismic energy.
-
7. Type of seismic wave which travels at a relatively slow speed.
-
9. Vibration of the earth, produced by the sudden slippage along a fault,
releasing energy.
-
11. The layer of the earth between the crust and the core.
-
13. Small seismic tremors preceding a large tremor.
-
17. Name of a scale designed to measure earthquake magnitude.
-
19. Type of seismic wave which travels fastest.
-
20. While earthquakes may be measured at the surface, they always occur
somewhere - - - - - - the earth.
-
23. An indication of the destructive effects of an earthquake at a particular
place.
-
24. The rigid outer layer of the earth, including the crust and the outer
mantle.

-
2. Mass wasting which moves down slope in a fairly coherent manner, along
a defined surface.
-
3. Measurement scale used for classifying the degree of earthquake damage.
-
4. Large fractures in the earth's crust along which there is movement.
-
6. Theory whereby rocks along a fault zone behave like springs (2 words).
-
7. The science of earthquakes.
-
8. The point at the earth's surface where an earthquake is felt most intensely.
-
10. Small earthquakes which follow a major tremor.
-
12. The total amount of energy released during an earthquake.
-
14. Type of seismic wave which cannot pass through liquids.
-
15. Mechanically traced record of an earthquake.
-
16. Elastic energy which, when stored up in rocks along a fault zone, will
deform the rock.
-
18. The outer, relatively thin rock layer of the earth.
-
21. This type of material causes the speed of all types of earthquake waves
to increase.
-
22. The point within the crust where the earthquake actually occurs.
