At the trial of three former TEPCo executives, an employee of a branch company testified that in 2008 he was asked to reduce the height of the tsunami he had estimated. While working for Tokyo Electric Power Services Co. (TEPSCO), the witness played a key role in calculating the magnitude of the tsunami that could hit the Fukushima dai-ichi and dai-ni power plants. From the official data, he found that a wave of a height of 15.7 m could occur. During a presentation of these results at TEPCo headquarters in March 2008, he was asked if it was possible to reduce the height obtained by changing the calculation method. The witness would then redo calculations by changing assumptions, but would again have reached the same height. He explained to the court that in the end, his prediction was not accepted. TEPCo then concluded that a dike 10 m high would be sufficient. And this dike has never been built … We know what’s next.
