The correct statement is:
Love waves are surface waves and cause horizontal shifting, Rayleigh waves are surface rolling waves.
Here's a brief explanation of the two types of waves:
-
Love Waves: These are surface seismic waves that cause horizontal shifting of the ground. They move in a horizontal motion, perpendicular to the direction the wave is traveling.
-
Rayleigh Waves: These waves also travel along the surface but have a rolling motion, resembling ocean waves. They involve both vertical and horizontal ground movement, causing the ground to move up and down and side to side.
In summary, Love waves move horizontally and are primarily responsible for horizontal ground displacement, whereas Rayleigh waves have a rolling motion and cause both vertical and horizontal ground displacement.
