Well I had thought that too, about sinking buildings, but then why would they sink at an even rate? The buildings are still level, which may point to added soil instead. Some of the items appear to have been shifted by the soil around them as well, some of the statues on Easter island and the square stone arch. Others however, many of the brick city scapes with half buried widows, can be explained by the city adding infustructure and building the new road on top of the new pipes, wires and tunnels. Each photograph would need a forensic review, time, location, history but thats a lot of work. I do believe there is substantive evidence that shit of a cataclysmic type has happen and will happen again however.
