Here’s a better streetview link. You can see the dirt berm that the aircraft hit is located far inside the perimeter wall. Also the wall is pretty dang thin and would not have stopped a 737 like that.
New pics in the media seem to show most of the wreckage came to a stop between the dirt berm and the perimeter concrete wall. At least one of the engines looks like it reached and penetrated the wall.
