Inundation and Damage by Run-up Tsunami of 2011 in the Sendai Plain, Japan

摘要

After the tsunami of the 2011 off the north-east Japan Earthquake, a survey of the disaster in the residential area of the coastal plain of Miyagi Prefecture was carried out. The damage of structures is explained by photos. It emerges that the tsunami height is more than 8 m on the shore, the inundation depth decreases along the run-up distance as far as 4 km inside from the coast and the state of the houses in the Yuriage town changes at 1.2 km from the coast from destructed into surviving. An experimental record of run-up tsunami suggests that a velocity at the front of tsunami is very strong at a shoreline.
