One more issue going on with the picture; it just seems to fracture into large chunks.
Since the moon isnt anywhere near the roche limit, those large chunks would just gravitate back to one another and not be torn apart into a ring. it would form a weird jagged moon, while all asteroid sized pieces will be attracted to and start colliding, giving the moon a new skin of craters.
although if enough force was used to blast it into small pieces, the varying orbits of all things would create massive moon kessler syndrome forming a ring.
