Even the 2011 Japan earthquake would change things, IIRC the distance between Japan and the US changed by 11 feet, and that is way bigger than the accuracy to which the position of the moon is known.
What is more, Japan didn't move as a rigid block. Different parts of Japan displaced by a different amount as a result of the stress release during the earthquake.
