Across
- 3. slower and second body waves to be detected
- 5. stress rocks that have equal pressure from all directions
- 6. breaks where the rocks have moved
- 9. amount energy released by an earthquake
- 10. detects and records seismic waves
- 12. caused by an underwater earthquake
- 13. seismic waves that travel on Earth’s surface
- 15. seismic waves that travel through the interior of the Earth
- 16. spot on surface above the focus
- 20. fastest and first body waves to be detected
- 21. amount of shaking and damage done by an earthquake
- 22. place where rocks first move
- 25. measures magnitude on a scale of 1-10
- 28. upward bulge
- 29. where the rock bends
- 30. created by compression stress
