Across
- 4. Where tectonic plates meet
- 7. An instrument that records seismic waves
- 8. Secondary waves; slower than P-waves and move material perpendicular to the wave direction
- 10. When saturated soil loses strength and behaves like a liquid while shaking
- 11. The point on Earth's surface directly above the earthquake's origin
- 13. vertical rise of land due to tectonic forces
- 14. Primary waves; fastest seismic waves that compress and move material in the direction they travel
- 15. Vibrations that travel through the earth during an earthquake
Down
- 1. A large sea wave caused by an underwater earthquake
- 2. The location inside the Earth where the earthquake starts
- 3. The severity of shaking at a specific location (Mercalli Scale)
- 5. movement of rock, earth, or debris down a slope
- 6. A fracture in the Earth's crust where movement occurs
- 8. Slowest waves that travel along Earth's surface and cause the most damage
- 9. A smaller earthquake following the main shock
- 12. A scale used to measure earthquake magnitude
- 16. A measure of the energy released during an earthquake
