From the additional pictures it looks like the left engine came to rest off the hard tarmac in the soft dirt shoulder. In photo No. 4 it appears like the lower part of the engine nacelle is partially dug into the ground, or, the ground the engine is resting on is lower the the tarmac itself (I can't really tell which). In either case, the lower engine position allowed the aircraft to "roll" more to the left than it could/should on a hard surface. With the remaining gear in tact, the additional roll caused the tail to touch the ground and pushed the right front evac slide up too high.
