Answer 1

If you see the ground moving up and down during an earthquake, you are probably experiencing **Surface waves**. Surface waves are the seismic waves that travel along the Earth's surface and are responsible for much of the shaking and damage during an earthquake. They typically cause the ground to move in a rolling or up-and-down motion.
