Description
Seismic waves are the waves of energy caused by the sudden cracking of the rock under the energy that the rock could not bear anymore.
Seismology is the profession that studies these waves and earthquakes that generate them. There are two categories for seismic waves, one that are body waves and the others are surface waves.

Body Wave v. Surface Wave
Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet and cannot go inside the crust or move in the mantle.
Surface waves move on lower frequency than body waves. Surface waves cause most of the destruction after an earthquake despite that it comes second.

Primary Waves
Fastest wave
Arrives first
Can move through solid rock and fluids, like water or the liquid layers of the earth.
It pushes and pulls the rock, moving them left and right.
Also known as Compressional Waves.

Secondary Waves
Slower than Primary Waves
It can only move through solid rock.
It move rock particles up and down or side-to-side.

Love Waves
It's the fastest surface wave.
Moves the ground side-to-side almost as a curling motion like a snake.
Love waves move in horizontal motion.

Rayleigh Wave
Rolls along the ground
It moves the ground up and down, and side-to-side.
Most of the shaking felt from an earthquake is due to the Rayleigh wave.
