Chatter marks is a common term used to describe a rippling pattern of half circle marks that appear on hardwood floors as a result of improper sanding.
Chatter can be caused by a loose sub floor just as an example.
Rippling in a wood floor is called chatter if the ripples are less than 1 1 2 inches apart and waves if the ripples are more than 1 1 2 inches apart.
