Report Problems: Presented by Prof. Ikeda (1) "The role of fluid in the crustal processes" Fluids play a vital role in virtually all crustal processes such as earthquakes, volcanoes, plate tectonics, et al. The questions are: What is the current state of fluid; how is the fluid moving; how is it transporting mass and energy in the crust. (2) "Expectations to the Ultra Deep Drilling in the earth" What would you like to research on the earth, if we can drill the Ultra Deep Borehole deeper than 10 km in the crust. Or describe what's expected of the deep borehole?
