Rikuzentakata City in Iwate Prefecture, for example, saw subsidence of 84 centimeters, which led to flooding of coastal areas and roads at high tide, often hampering recovery and rehabilitation eff orts. The level of protection against storm surges and fl ooding was signifi cantly diminished in the Sendai Plain. The area below mean sea level more than tripled (from 3 square kilometers [km2] to 16 km2) after the earthquake (map 3.1), as revealed in the MLIT’s laser profiling survey. The MLIT produced subsidence maps and revised downward the water levels at which it issues flood warnings."
