Study Notes
Seismic Waves
- Seismic waves are generated by earthquakes and travel through the Earth.
- Two main types: Body waves and Surface waves.
Body Waves
-
P-waves:
- Fastest seismic waves.
- Travel through solids, liquids, and gases.
- Compressional motion: particles move in the same direction as the wave.
- Less damaging than other waves due to less ground motion.
-
S-waves:
- Slower than P-waves.
- Travel only through solids.
- Shear motion: particles move perpendicular to the direction of the wave.
- More destructive than P-waves, causing stronger ground motion.
Surface Waves
-
Travel along Earth's surface.
-
Typically responsible for the most earthquake damage.
-
Love Waves:
- Horizontal shearing motion, moving the ground side-to-side.
- Faster than Rayleigh waves, but slower than body waves.
- Particularly damaging to buildings due to their shearing effect.
-
Rayleigh Waves:
- Similar to ocean waves, causing a rolling motion.
- Move the ground both vertically and horizontally in an elliptical path.
- Slowest seismic wave.
- Can cause significant damage due to the rolling motion.
Earthquake Wave Arrival Order
- Seismic waves arrive at seismographs in a specific order:
- P-waves arrive first, providing early warning of an earthquake.
- S-waves arrive second and cause more damage than P-waves due to higher energy.
- Surface waves (Love and Rayleigh) are responsible for the most severe ground shaking and destruction.
