This year, on March 11th, Eastern Japan was struck by a major earthquake and tsunami of an unprecedented scale. This large earthquake and tsunami not only caused destruction along the coastline of the Tohoku region, it subsequently led to the accident at the Fukushima No.1 Nuclear Power plant. The fatalities and missing people from this compound disaster has reached about 20,000 people. Our condolences to those lost their lives through this disaster and our wishes to those suffering.
Even in the prefecture of Ibaraki, the disaster caused serious effects including damage to reclaimed land, harbours, and coastal regions, as well as livelihood disruptions related to industry and agriculture, refugees, and the compounded nuclear accident. Although the damages in Ibaraki were small compared to the damages to the three prefectures in the Tohoku region, the disaster has been a historical shock to Ibaraki. In order to create plans to prevent a shock of such magnitude to repeat itself and to ensure the safety of the region, there are many lessons to be learned from this incident.
With these thoughts, Ibaraki University started assessing the damages of the Great Earthquake and Tsunami at the end of March. In this research group, 120 researchers and students in total participated from the university’s five departments and center. The work was carried out in collaboration with Ibaraki Prefectural government, Oarai Town, Oarai University of the Sea NPO, Joyo ARC, Tsukuba University, JSCE Ibaraki, Geological Society of Japan, and North Ibaraki Geopark.
The research team published an early edition damage report on May 31. Due to the expediency of the publication, many ideas and data were not fully included or analyzed. Thus, we continued our research to correct the data and results. In this revised edition, we have included these corrections. We hope this report will serve to help in the local recovery and renewable and in building a sustainable, safe society.
The final version (Japanese) is now available.
