GEOLOGY

Detailed explanation-1: -Rayleigh Waves-surface waves that move in an elliptical motion, producing both a vertical and horizontal component of motion in the direction of wave propagation. Love Waves-surface waves that move parallel to the Earth’s surface and perpendicular to the direction of wave propagation..

Detailed explanation-2: -A Rayleigh wave rolls along the ground with a more complex motion than Love waves. Although Rayleigh waves appear to roll like waves on an ocean, the particle motion is opposite of ocean waves. Because it rolls, it moves the ground up and down, and forward and backward in the direction that the wave is moving.

Detailed explanation-3: -Rayleigh waves cause the ground to shake in an elliptical pattern. This motion is similar to that observed in ocean waves. Of all the seismic waves, Rayleigh waves spread out the most, giving them a long duration on seismograph recordings.

Detailed explanation-4: -Rayleigh waves move the surface of the earth around in a circle, forward and down then back and up. This is the same as the motion in an ocean wave. Deeper in the ground, Rayleigh and Love waves get smaller.

Detailed explanation-5: -Ground Shaking From Earthquakes An earthquake generates seismic waves that pass through the ground. As those waves pass near or underneath your house, it can move from side to side and up and down. The shaking your house experiences depends on how far it is from the fault and the soil under and around it.
