Satellite imagery is the most effective method of revealing such data.
Overall, the surface of the Earth is divided into a dozen or so large plates near the surface, and several smaller ones. As these plates move in relation to one another, stress and strain builds up in the rock. When the strain reaches a certain point, the rocks snap, and the ground moves. Sometimes, though, the ground slips over time. Along the Anatolian Fault, as well as the San Andreas Fault in California, this process, called slippage, can crack sidewalks and move buildings in a slow creep lasting many years.
