Geodynamics International

The Geodynamics Project is an international program of research on the dynamics and dynamic history of the Earth with emphasis on deep-seated foundations of geological phenomena. This includes investigations related to movements and deformations, past and present, of the lithosphere and all relevant properties of the Earth's interior and especially any evidence for motions at depth. The program is an interdisciplinary one, coordinated by the Inter-Union Commission on Geodynamics (ICG) established by ICSU at the request of IUGG and IUGS, with rules providing for the active participation of all interested ICSU Unions and Committees. This seventeenth report prepared by the secretariat is expected to be the final issue in the Geodynamics International series.
