Is this something that just happened? The fascia is raised, but the window is not. The first place I would look is the roof. Remove the soffet and look to see if the rafters are still attached to the plate. Look for broken rafters from snow load. Set up a transit and shoot the top plate, window sills, bottom plate and the front of the house. Depending on the area, some 100 year old houses are balloon framing and the corner post gets eaten by bugs causing it to let the top plate fall. It looks like the gap above the window is larger on one end than the other. Once again, check the roof rafters.
