Context as given in the above cited source: "Fudai village developed along the Fudai River. It suffered from the 1896 and 1993 tsunamis that propagated along the river. In 1984, 15.5 m high tsunami gates were constructed to close the river mouth in case of tsunamis. Fudai was the location of a successful countermeasure structure that protected the village from the 2011 tsunami. The 17 m high tsunami flowed over the gate but inundated only a few hundred meters past the gate (Nikkei newspaper, 2011), as shown in Fig. 10, left. Most of Fudai village, including the evacuation shelters (primary and secondary schools), was protected, as shown in Fig. 10, right, and no loss of human life was reported (Token, 2011). If there had not been a tsunami gate, the tsunami would have damaged the center of the village (Iwate prefecture, 2011)."
