DOI: 10.1007/s00024-017-1585-z

Abstract: We consider the main factors that affect underground water flow including aquifer supply, collector state, and distant earthquakes seismic waves’ passage. In geodynamically stable conditions underground inflow change can significantly distort hydrogeological response to Earth… read more here.
