Abstract
⺠At the underground station of Matsushiro, a decrease in gravity is observed when it rains. ⺠We analyze the data of “precipitation” inside the tunnel, as well as soil moisture at the surface of the hill. ⺠The soil layer plays a role of a water reservoir, whereas the body of the hill acts as a conduit of water. ⺠The linear rate of gravity recovery is given an explanation from a hydrological viewpoint. ⺠The underground observatory of Matsushiro provides an ideal labolatory for combined studies of gravimetry and hydrology.
