How are earthquake waves UNLIKE a drop of water on a pond?
Part 2/2 Comparing seismic waves to ripples in water. This animation explores how seismic waves are UNLIKE ripples on water. Dr. Geophysics helps explain 4 significant differences.
- Potential energy builds quickly in water drop; builds over many years in Earth
- Water drop is above the surface of Earth; earthquake is below the surface
- Water waves travel in concentric spheres; changing geology causes changes in the speed of the seismic waves
- Drop falls at 2 to 600 mph; seismic waves travel at 2,000 to 28,000 mph!
