Subsidence is a type of mass movement that involves principally a downward movement or displacement of surface material caused by natural or artificial removal of underlying support. Various methods that could be used to monitor subsidence include conventional practices, instrumented in ground sensing systems. The conventional techniques include repeated optical leveling and GPS surveys, ground reconnaissance, photo geological analysis, groundwater monitoring, and tape extensometers
