The Love wave is a result of the interference of many shear waves (S-waves) guided by an elastic layer, which is welded to an elastic half space on one side while bordering a vacuum on the other side. … Love waves travel with a lower velocity than P- or S- waves, but faster than Rayleigh waves.
Keeping this in consideration, what is the characteristics of Love waves?
Love waves are a major type of surface wave having a horizontal motion that is shear or transverse to the direction of propagation. The velocity of propagation of any body wave in any homogeneous, isotropic material is determined by the elastic moduli and densities of the material through which it passes.
Subsequently, how fast is a love wave?
How do waves move in Love waves?
Love waves have a horizontal motion that moves the surface from side to side perpendicular to the direction the wave is traveling. Of the two surface waves, Love waves move faster. Rayleigh waves cause the ground to shake in an elliptical pattern. This motion is similar to that observed in ocean waves.
Who discovered Love waves?
Augustus Edward Hough Love
What is the characteristics of Love waves and Rayleigh waves?
Love and Rayleigh waves are guided by the free surface of the Earth. They follow along after the P and S waves have passed through the body of the planet. Both Love and Rayleigh waves involve horizontal particle motion, but only the latter type has vertical ground…
What are the two types of body wave?
Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves).
Do Love or Rayleigh waves cause more damage?
Love waves cause more damage than Rayleigh waves, but both are highly destructive because they occur near the surface of the Earth.
Why are love waves the most destructive?
Love waves have a particle motion, which, like the S-wave, is transverse to the direction of propagation but with no vertical motion. Their side-to-side motion (like a snake wriggling) causes the ground to twist from side to side, that’s why Love waves cause the most damage to structures.
How are Rayleigh waves created?
Rayleigh waves are formed when the particle motion is a combination of both longitudinal and transverse vibration giving rise to an elliptical retrograde motion in the vertical plane along the direction of travel.
Can Rayleigh waves travel through gas?
These waves can travel through solids, liquids, and gases. … There are two major kinds of surface waves: Love waves, which are shear waves trapped near the surface, and Rayleigh waves, which have rock particle motions that are very similar to the motions of water particles in ocean waves.
What is the characteristic of Rayleigh waves?
Rayleigh wave is a secondary wave characterized by low frequency and strong energy, propagating mainly along the interface of medium and rapid attenuation of energy with increase in interface distance. The same as reflected wave and refracted wave, Rayleigh wave also contain subsurface geological information.
