Sponsored by the Coasts, Oceans, Ports, and Rivers Institute of ASCE; Port and Airport Research Institute of JapanOn March 11, 2011, a magnitude 9.0 earthquake rumbled off the east coast of Japan, followed by a tsunami that generated waves more than 18 meters high. The earthquake and tsunami caused devastation throughout the Tohoku and Sendai regions of Japan, killing nearly 16,000 people and causing damage estimated at more than US26 billion.For seven days in May 2011, an ASCE/COPRI Coastal Structures Team investigated the earthquake and tsunami effects specific to engineered coastal structures, coastal landforms, and coastal processes in northeast Japan. Joined by colleagues from Japan
