A large number of irrigation dams have been constructed in Japan. Strong earthquakes have often occurred and seismic observations in fill dams are very important for safety and countermeasures. Seismometers have been installed in 156 high irrigation dams since 1954 and seismic accelerations observed. Dynamic dam behavior is investigated by seismic observation records at the National Institute for Rural Engineering in cooperation with dam managers.
