During the March 11 earthquake, some areas along the bay area in Tokyo suffered damage from liquefaction. The above images are from Toyosu and Shinonome in Koto-ku.
Between 1881 and 1930 the following reclaimed land was created:
- Tsukishima 1~4 Chome
- Minato-ku’s coastal area (Shibaura 1~4 Chome, Kaigan 1~4 Chome)
- Shiomi area in Koto-ku
- Edagawa, Koto-ku
- Tennozu Isle, Shinagawa-ku
Below is a map showing the reclaimed land in Tokyo Bay up until 2002. A total area of 17,580,000 Tsubo (58 million sqm) of land was reclaimed between the 1860s and 2002.
The following is a survey map of Tokyo showing the areas at risk of liquefaction in a large earthquake. The data is provided by theTokyo Metropolitan Government’s Civil Engineering Center.
Most of Tokyo is low-risk, but the low-lying areas towards Tokyo Bay and the man-made islands are at high risk of liquefaction. These areas, in particular the entire area east of Shinagawa Station, were once part of Tokyo Bay and have been reclaimed over the years.
Green: Areas with almost no risk of liquefaction
Yellow: Areas with average risk of liquefaction
Pink: Areas with high risk of liquefaction
