Usually when we say something "cratered" we mean that it fell rapidly, as one might imagine a meteor would fall from space and impact the earth with enough force to produce a crater.

It doesn't get used very often in my experience.

As mentioned in another post, "crater up to" is a bizarre formation of words. "Rents fall by up to 31%" is perfectly understandable phrasing, but replacing "fall" with "crater" makes it sound very strange.
