Here's a photo from the recent Christchurch earthquake in NZ: http://www.novafm.com.au/photo_road-split-in-sumner_259344
Notice that the crack starts off to one side but quickly runs right down the middle of the road between the lanes. Just like taking a piece of paper, putting a sharp crease down the middle and pulling the two halves apart, the tear might start anywhere but will quickly run to the crease and the paper will come apart quickly and neatly.
No photoshop required.
