A change of social recognition about liquefaction risk and influence on land price

Abstract

The liquefaction occurred in the Tokyo Bay area by the Great East Japan Earthquake in 2011. It caused serious damage to buildings and infrastructure and changed a social recognition about liquefaction risk. This paper examines that land prices are lower in risky areas than in safe areas after the Great East Japan Earthquake occurred and the liquefaction risk maps was open to the public. For this purpose, I use the liquefaction risk maps that have been compiled by Tokyo Metropolitan Government since 1983. Finally, this paper explores policy implications of the results in order to decreasing liquefaction damage.
