Short-term and long-term physical, environmental, and economic impacts of the Tohoku earthquake and tsunami

On March 11, 2011, a massive earthquake of magnitude 9.0 hit the northeast coastal areas of Japan. This earthquake, commonly called as Tohoku earthquake, generated massive tsunami wave resulting coastal inundation in Iwate, Miyagi, and Fukushima Prefectures, and most importantly, nuclear meltdown of Fukushima nuclear plant. Hence, this triple disaster (earthquake, tsunami, and nuclear) killed so many people. As of August 10, 2015, 15, 892 people are killed, 6,152 people are injured and 2,573 people are still missing1. About 124,664 buildings were completely devastated whereas 274,641 buildings were partially collapsed having significant impacts on other infrastructures as well. This disaster damaged 116 bridges, 4,198 section of roads, 29 segments of railways and induced 207 landslides in the affected region.

The striking difference of this earthquake is the nuclear power plant crisis. After the Chernobyl disaster in 1984, this event created heated debates about the dependency of energy supply on nuclear power. Also, concerns were raised worldwide regarding the safety standards to combat such mega events. Krausmann and Cruz (2013)2 studied the impacts of earthquake and tsunami on chemical industry where they concluded that this event dramatically highlighted the vulnerability to natural hazard triggered technological (Natech) accidents of a well prepared countries like Japan and suggested to revisit the current practices and policies to safeguard surroundings from such facilities. The same report highlights the disproportionate impact of chemical industries in the different location within the affected region. For instance, no lives were lost in Chiba industrial complex while four people were killed in Sendai refinery.
