The Railway Technical Research Institute opened the Center for Railway Earthquake Engineering Research on April 1, 2014 amid increasing concern about the risk of seismic disasters caused in particular by massive earthquakes. Violent earthquake disasters are becoming more common and more complex. In order to achieve safer railway systems able to cope with these conditions, the center was established as a unique "base" for railway-seismic technology in Japan. The center also integrates RTRI's research resources on quake-motion, seismic design and countermeasure, and early warning. This report introduces the role of CREER and recent research into earthquake-related technology.

A great earthquake of magnitude M9.0, occurred around 14:46 pm on March 11, 2011, at an epicenter at an undersea depth of 24 km off the Sanriku coast line, an area in the northeastern part of the main island of Japan. The earthquake was named as "2011 off the Pacific Coast of Tohoku Earthquake." A large-scale fault slide occurred at the plate boundary stretching from the offshore area of Iwate to Ibaraki, and caused heavy tremors of level 7 Japanese Seismic Intensity at Kurihara City in Miyagi Prefecture, and of level 6+ in wider areas in Miyagi, Fukushima, Ibaraki and Tochigi prefectures. This article outlines the outline of the earthquake, and gives an overview of RTRI activities to support the recovery of railway networks damaged by the earthquake. The comparisons of the actual shaking waves of this earthquake with design waves in the Design Standards for Railway Structures: Volume of Seismic Design is also described.
