American Society of Civil Engineers ASCE Tohoku Japan Earthquake and Tsunami 2011 Survey Report

Gain technical insights into one of the most significant seismic events in modern history. This professional report covers the 2011 Tohoku earthquake and tsunami, which reached a 9.0 magnitude and impacted over 2000 km of the Japanese coastline. From metropolitan Tokyo to the northern reaches of Honshu, the scale of damage to port and harbor facilities was immense. This publication presents the findings from the ASCE-COPRI Port and Harbor Facilities Field Survey Team. Working in close collaboration with Japan's Ports and Airports Research Institute, the team conducted extensive field reconnaissance throughout May 2011. The content focuses specifically on the effects of the earthquake and tsunami on port waterfront structures and their ancillary components. For engineers, researchers, and students of earth sciences, this document provides a detailed look at how major maritime infrastructure responds to extreme natural disasters. It serves as a vital record of the damage observed and the specific impacts on coastal facilities during this historic event.
