Special Issue on the Great East Japan Earthquake Disaster: Part IV
The basic policy of the Journal of Disaster Research (JDR), as a multidisciplinary academicjournal, is to cover all types of disasters ? except for war ? through a broad comprehensive perspective. Since its inaugural issue in August 2006, the JDR has been published bimonthly,with six issues a year. 2015 marks the tenth year since the JDRfs first issue. Among the many events happening during this decade is the March 2011 Great East Japan Earthquake Disaster which was induced by the 2011 off the Pacific coast of Tohoku Earthquake.This event had two major features ? that the tsunami accompanying the earthquake caused the main damage and that it triggered a nuclear hazard accident at a nuclear power plant. The 2011 Great East Japan Earthquake Disaster was a unprecedented earthquake disaster called catastrophic hazard following two others ? the 1923 Great Kanto Earthquake Disasterthat leveled Tokyo and the 1995 Hanshin Awaji Earthquake Disaster that destroyed parts of Osaka and Kobe. In view of this catastrophic hazardfs scale, the JDR decided to publish special annual issues on the Great East Japan Earthquake Disaster for five years since 2012 in addition to its regularissues. No publication fee was charged to contributors and support was asked from corporations. Papers on the special issues are published mainly online as an e-journal though printed editions are published for archival purposes. The current issue is the fourth of these special issues, and contributors have covered the 2011 disaster from many a wide range of perspectives. 21 papers were submitted and 8 papers are accepted for publication after peer review. The editors are confident that, like the previous three issues, this issue fully measure up to the quality that was expected for the special issue. I wish to express my gratitude to the contributors and reviewers and to thank corporations for their invaluable support.
