The basic research toward an establishment of new criteria for evaluating building damage by the pre-modern earthquakes

本研究的目的是在历史文献的基础上，考虑历史记录的可靠性和建筑物的特点，对历史大地震造成的建筑物破坏情况进行评估，建立建筑物破坏情况评估的新方法和新的地震烈度评估标准。这项研究的目标地区是日本中部的近木区，那里仍然有大量具有高可靠性的历史记录和当时用手工技术建造的建筑结构。这项研究使得比以往的研究更合理地评估建筑物的破坏和地震烈度成为可能。

The purpose of this study is assessing the damage situation of buildings caused by historical large earthquakes on the basis of historical documents, in consideration of reliability of historical records and the characteristics of buildings, and establishing new method to evaluate damage situation of buildings and new criteria to estimate seismic intensity. The target region in this study was the Kinki district, Central Japan, where historical records with high reliability and building structures constructed by crafting technique in those days are still abundant. This study made it possible to evaluate more reasonable building damages and seismic intensities than previous studies.
