it is likely that the printed layer started to theright hand side of the picture and progressed towards the left,
is live z is too big a negative number, each successive line pushes the last layer slightly out of alignment and eventually there is too much movement, which causes these ripples. additionally, your print bed may be microscopically higher where the ripples are appearing, this can also cause rippling, and can be adjusted with live 'Z' adjust...
see the thread, 'Life djust, My way' on the forum
an additional LCD menu option allows you to cause differential 'Z' adjustment in 4 areas, left, right back and front.
and if you are brave enough, there is hyperfine bed levelling ( follow the thread on the forum)
I try to make suggestions that I believe to be well founded and safe,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions,
what you do, is YOUR responsibility.
