• In Earthquake of the Pacific coast of Tohoku, damage by the liquefaction-Fluidization occurred frequently in Chiba. Particularly in Asahi-shi, much liquefaction-Fluidization damage happened in slight highlands such as dune, where iron sand had been mined in 1960s. Because such the grounds are loose by being digged, liquefaction is easy to happen In addition, the liquefaction is related to the height of the groundwater. By examining the places where iron sand was mined and dune was in the past, it is found that someplace may have happen liquefaction-Fluidization. This study is useful for production of hazard maps.
