Tsunami deposits are useful in attempted reconstructins of prehistoric tsunamis. Geological analyses of tsunami deposits can provide estimates of several parameters of tsunamis, such as recurrence intervals and inundation areas. To assess the history of paleotsunami, we investigate the tsunami deposits around the coastal lowlands on the eastern margin of the Sea of Japan. These studies provides useful information for advancing tsunami disaster risk assessment in coastal lowlands.
In addition, we are active in the practice of disaster education.
