Across
- 1. Scale that rates earthquake intensity based on damage and observations
- 3. Elastic _____ theory explains why strained rocks snap back to cause shaking
- 4. Scale that measures earthquake magnitude using a logarithmic scale
- 8. Point on Earth's surface directly above the focus
- 12. Secondary seismic wave; slower side-to-side motion through solids only
- 13. Using distance data from 3 stations to locate an epicenter
Down
- 1. The total amount of energy released by an earthquake
- 2. Love wave; a fast surface wave causing side-to-side horizontal shaking
- 5. Underground point where rock first breaks along a fault
- 6. The measure of shaking and damage at a specific surface location
- 7. The scientific study of earthquakes and seismic waves
- 9. Primary seismic wave; fastest and compresses through all states of matter
- 10. Surface wave that rolls along the ground in an elliptical motion
- 11. Break in Earth's crust where rock blocks slide past each other
