Geomorphology, Natural environmental studies
Our interest is focused on the interrelations between uplift and/or subsidence of rock in the continental crust, and erosion, transport and deposition of rock. Through field work and drilled core analyses, we try to reconstruct sea-level changes, river-bed fluctuations, rates of rock uplift and subsidence back 1 million years. We also try to evaluate the magnitude and frequency of past events such as earthquakes, slope failures, and floods with a view to preventing natural disasters.
