Below right, vertical aerial photograph of Arahama Beach, Sendai, Japan showing extensive damage to structures on the coastal plain. The detached breakwater and coastal seawall are still visible, and they appear to have not undergone significant damage although the tsunami overtopped both structures. Photograph taken on March 12, 2011 after the recent tsunami. [Larger local version].
