BLOCK CAVING  (video)
 
Influence of geological structures on the development of surface subsidence, contours illustrate vertical displacements 10cm(red)/1m(blue).  

Contrasting with the animation given below, note the role of joint orientation in initial cave propagation and the governing role of a fault in subsidence development.
