The tsunami that hit Fukushima Prefecture on March 11 was particularly high--possibly up to 21 meters--along the coast in the center of the prefecture where the Fukushima No. 1 nuclear power plant is located, a survey has found.
The height of the tsunami was previously assumed to have been about 15 meters at the nuclear plant, but this could not be confirmed because the area within a 20-kilometer radius of the plant is designated a no-entry zone.
Researchers including Shinji Sato, a professor at the University of Tokyo, obtained permission from local governments to enter this zone, and for the first time since the tsunami, were able to survey coastal areas Monday and Tuesday. (Yomiuri)
