The 2011 eastern Japan great earthquake disaster: Overview and comments

TLDR

The article reviews the causes and impacts of the 2011 eastern Japan earthquake and tsunami, comments on Japan’s response, and stresses the need to investigate tsunami preparedness of coastal nuclear plants and develop a collaborative disaster‑management framework. The authors conduct a brief review of the earthquake and tsunami’s causes, impacts, and Japan’s response measures. Mass losses were mainly due to the quake and tsunami exceeding local coping capacity, the nuclear plant crisis amplified short‑ and long‑term impacts, and although Japan’s post‑1995 preparedness mitigated damage, further improvements are needed.

Abstract

This article briefly reviews the causes and impacts of the massive eastern Japan earthquake and tsunami of 11 March 2011, and comments on the response measures taken by Japan to cope with this devastating disaster. Mass losses occurred mostly because the intensity of the quake and the induced tsunami exceeded local coping capacity. Particularly, the nuclear power plant crisis triggered by the tsunami significantly increased the short- and long-term impacts of the disaster. While the coping capacity Japanese society built after the 1995 Hanshin-Awaji great earthquake tremendously mitigated the damages, there is room for improvement despite Japan’s great efforts in this disaster. Investigating the tsunami preparedness of the coastal nuclear power plants is an issue of paramount importance. In response to future large-scale disasters, there is an urgent need for a highly collaborative framework based on which all available resources could be mobilized; a mutual assistance and rescue system against catastrophes among regions and countries on the basis of international humanitarian aid; and further in-depth research on the multi-hazard and disaster-chain phenomenon in large-scale disasters and corresponding governance approaches.
