TOKYO, Aug. 9 (UPI) -- Japan's March 11 tsunami destroyed some 120,000 buildings and damaged 220,000 others, the government's first comprehensive damage survey indicates.
The survey found the percentage of destroyed buildings was markedly higher in areas where the onshore water level surpassed 6.6 feet, The Yomiuri Shimbun reported. The tsunami followed a powerful magnitude-9 earthquake.
Of the destroyed buildings, some 78,000 were completely washed away by the tsunami, the Land, Infrastructure and Tourism Ministry said.
A total of about 132,000 acres of land was submerged by the tsunami in six prefectures in the Tohoku and Kanto regions.
The survey, conducted in June and July, covered uninhabited buildings such as factories, offices, schools and community centers as well as houses.
