Did you find primary waves, secondary waves, or surface waves?
Primary waves are waves that waves that cause particles in the ground to make a push-pull motion,Like a spring!
Surface waves are waves that cause particles in the ground to move up and down in a rolling motion, similar to ocean waves!
Secondary waves are slower than Primary waves and cause particles to move up and down in right angles relative to the direction the wave travels!
