| Abstract | Geothermal energy is renewable but its sustainability is not self-evident. Therefore the management of geothermal reservoirs is important to maintain the sustainable production of geothermal energy. We estimated the mass balance in the geothermal reservoir during exploitation at Hatchobaru geothermal field, central Kyushu, Japan based on the changes in gravity and Gauss |
