Context as given in the above cited source: "The residents of Minami-Sanriku town have high tsunami awareness because of previous experience with tsunamis. The maximum height of the tsunami in Minami-Sanriku town was >10 m in some areas, whereas the average height of past tsunamis was <5 m. Seawalls and tsunami gates were constructed at +4.6 m MSL after the 1960 Chile tsunami (Minami-Sanriku town, 2011) and residents did not expect such a large tsunami, because the first tsunami warning had prediced 3 m in Miyagi prefecture. Tsunami evacuation drills are conducted every year. However, the tsunami gates and seawalls were overwhelmed and did not stop the 2011 tsunami, which was higher than 15 m (Fig. 11, left). As a result, 95 % of the town, including the disaster prevention building, was destroyed (Fig. 11, right), and approximately half of the population was missing immediately after the tsunami. Approximately 1,000 people died or are missing as a result of the tsunami."
