Identification of Geoscientific Evidences in the Nuclear Disaster Trials: A Sociological Study of Science and Technology

This paper examines how geoscientific evidences are examined in the civil trial on nuclear power plant compensation and the criminal trial of TEPCO management.

In the judgment in the TEPCO criminal trial (Tokyo District Court, September 19, 2019), it was found that the management was aware of the possibility of tsunami (foresight). However, the Tokyo District Court found the executives not guilty because the headquarters' long-term evaluation was too weak to be reliable.

Then, is the reliability of the decision made by the management and the district court that dismissed the possibility of a tsunami earthquake off the coast of Fukushima Prefecture high? The scientific verification can be carried out, if the size of the probability is examined.

What is the meaning of the "reliability" given to the long-term evaluation by the Earthquake Headquarters from the viewpoint of science, technology and sociology?
