the 2011 off the Pacific Coast of Tohoku Earthquake Tsunami, railway structure

The huge tsunami generated by a 9.0 Mw earthquake (off the Pacific Coast of Tohoku Earthquake) and centered off the coast of Sanriku, Tohoku, on March 11, 2011, damaged 7 lines of the East Japan Railway Company. Bridge girders were swept away, piers were broken or tipped, and embankments and station buildings were swept away. This paper reports typical examples of railway structure damage due to this tsunami.
