Short summary
In Quetta, Pakistan where I have worked. Land Subsidence has created large scale fractures on the surface of the land, these fissures have damaged a lot of structures inside the city. According to our research work, the annual recorded subsidence rate in Quetta city is about 120 mm per year and the groundwater decline level is about 5 m per year. We measured land Subsidence using GPS units. These GPS units are capable of recording land deformation with sub-centimeter accuracy.
