Abstract

The present paper deals with damage analysis of residential lands in the 2007 Niigata-ken Chuetsu-oki Earthquake. Since severe damage to residential land was caused in Kashiwazaki, City, Kariwa Village, Izumozaki City and Jouetsu City by this earthquake, an official earthquake damage judgment for residential land was conducted after the earthquake. Damage analysis was done by using the results of the official damage judgment and the characteristics of damage was compared with those in the 1995 Hyogoken Nambu and 2004 Niigata-ken Chuetsu Earthquakes. Finally, countermeasures for improvement of residential land were proposed based on the result of the damage analysis.
