What are the characteristics of p-wave, s-wave, love wave, and rayleigh wave?

  • P (Primary) and S (Secondary) Waves are often correlated body waves with Seismic Waves, as in Earthquakes.  
  • The waves of body waves and surfaces compose an earthquake, but the waves of the body come first. Main is first, and secondary is, of course, second.

  1. P Waves are compressional, meaning they pass (compress) through a solid or liquid  by pushing or pulling similar to how the sound moves through the air. The material particles a P Wave passes through travel in the direction of energy from the P wave.  

It is called  

Wave Propagation Direction.

2. S waves are slower than P waves, and can pass only across solid rocks.  

  • S waves shift the particles that it moves up and down, or side by side (perpendicular to the strength of the S waves).

Surface waves can be classified into two forms of Earthquakes.  

The first one is called a Wave of Passion.  

The movement is basically that of S waves with no vertical displacement; it pushes the ground.

From side to side in a horizontal plane, but from right angles to the direction of propagation.

  • The horizontal shaking of Love waves is particularly damaging to the structural foundations.
  • The other surface wave form is called a Rayleigh wave.  

Unlike moving ocean waves, the Rayleigh waves move vertically as well as horizontally  in a vertical plane pointing in the direction the waves are heading in. Surface waves travel slower than body waves (P and S); and love waves typically travel faster than Rayleigh waves from the two surface waves.  

Forces of Love (do not spread by water) Can impact surface water only insofar as the sides of lakes and ocean bays moving water sideways like the sides of a vibrating tank, while Rayleigh waves can influence the bodies of water such as lakes by using their vertical aspect of motion.

-Traveling along the free surface of an elastic solid such as the earth -their movement is a combination of longitudinal compression and dilling resulting in elliptical point movement on the surface, spreading most in time, generating long seismograph wave length.
