Look at the enlarged image from MRO

It looks like it suffers from "vibration" or a double image... something
is wrong. Any ideas.

I don't see anything I would describe that way. The Sun was only 38°
above the horizon, so the low-relief terrain has a sort of embossed
look. Maybe that's what you are seeing?

The full resolution image of the hole,

shows details around the edge very clearly, with no sign of any imaging
problems.

Chris, I downloaded the image at your link, cropped it, and enhanced it
using the shadow/highlight filter in photoshop, and here is my result:

If you open it and zoom in, it appears that you can see a little more
detail inside the hole, though admittedly not much. But it does appear
that there is enough detail there to say that it doesn't go to china (or
what passes for such on Mars)! But it does appear to be quite deep. Also
note the area just to the north of ther image (assuming that north is
towards the top of the image). It looks to me as if there is a large
shallow depression there filled with scalloping sand dunes, as if the
bedrock is sinking or sagging a bit, so the karst in this terrain may even
be more extensive than the hole by itself would seem to indicate. Just my
two cents worth.
