The Construction of Earthquake Damage Data Archives for Earthquake Disaster Mitigation

Abstract eng:
The October 23rd, 2004, Mid Niigata prefecture earthquake attacked the Chuetsu area in central Japan, causing serious damage to major traffic arteries located in a mountainous region of tertiary sedimentary rocks. This earthquake occurred in an active folding area that is mainly in northeastern Japan from the north edge of Fossa Magna. It is thought that these damages indicate typical damage in active folding area. Therefore, for mitigation of the earthquake damage in active folding area, we collected data related to the earthquake damage and constructed earthquake damage data archives. The archived data are as follows, (1) Landform data by aerial photographs and LIDAR, (2) Ground data include boring data and microtremor data, (3) Strong ground motion records, (4) Research outcome and (5) Technical and investigation reports of rehabilitation and reconstruction. The data archives are going to be open to the public on the web. It is hoped that data archives will contribute to mitigation of the future earthquake damage in the active folding area. active folding, data archives, 2004 Mid Niigata Earthquake,
