Geophysics is a broad research field that studies solid Earth, oceans, atmosphere, upper-atmosphere, ionosphere and planets. Geophysicists take physical approaches to investigate various phenomena in these areas and study their structures as well as their long-term and short-term variations in order to clarify the formation and evolution processes of our mother Earth and the solar system. In recent years, as a natural science geophysics has been developing with a close relationship to our human society. During the last 60 years, Department of Geophysics has made great efforts and important contributions to establishing the framework of geophysics. We treasure the glorious history and tradition made by many of our seniors in the Department, and at the same time we are working to open new frontiers of geophysics.
