Movements of strata over coal seams can be caused by underground activities, e.g. tunneling, mining, etc. Vertical displacement in each stratum can develop in an upward manner from the stratum adjacent to the coal seam to the surface. Hence, it is well known that there are strong links between subsurface and surface subsidence movements.
