Subsidence is the motion of the ground surface as it moves down relatively. It can occur in a wide range of area. It is an impact of production of large mass and volume of saturation from the reservoir. It doesn't happen especially in geothermal fields only, but also in oil and gas industry, reservoir impoundment/ Hydropower plants. Large fluid volume production leads to the decrease of pore pressure inside reservoir. This decline disturbs the pressure stability and overburden pressure compress the pores. It results the drop in ground surface. The decrease in ground surface level induces a devastating effect in the construction of some facilities, such as building, pipeline, canal, and river. It may interrupt the balance in the ecosystems nearby. Near real time monitoring of subsidce will reduce the risk of possible damage and the other effects related to it. We propose the solution utilzing Interferometric Synthetic Aperture Radar (InSAR) based approch using openly avaiable EO data and tools for measure subsidence for minimizing subsidence impact in the geothermal field and reservoir impoundment/ Hydropower plants in general.
