International Strategy for Disaster Mitigation Laboratory (ISDM), one of the research fields of Regional and Urban Reconstruction Research Division at IRIDeS, aims to provide more practical international strategies for disaster mitigation/post-disaster recovery and to develop international frameworks that enable us to realize the strategies based on field surveys and data analysis. In order to clarify existing problems and make recommendations to the world for future disaster reduction, ISDM is researching on the relationship between disaster management and urban/regional space inside and outside of the country, through case studies of vulnerable areas including disaster-experienced cities.

One of our significant researches is urban vulnerability evaluation. Using the actual building damage data due to the 1995 Great Kobe Earthquake, Prof. Murao clarified the relationship between seismic ground motion and building damage. As a result, he constructed building vulnerability functions and proposed a method of building collapse risk evaluation for Tokyo.

Monitoring urban recovery of areas affected by the disasters in the world, ISDM quantitatively evaluates the urban recovery processes for planning future disaster risk reduction strategies. To date, our overseas research fields have been in Taiwan, Turkey, Sri Lanka, Thailand, Indonesia, Peru, China, Hawaii, New York, and Myanmar. In addition, Kobe, Tokyo, Kanagawa, and Sanriku Coastal Areas affected by 2011 Great East Japan Earthquake and Tsunami have been significant research objectives for us in Japan.

A research on the relationship between physical environment and disaster management is our current concern. Our challenge is to establish a systematic framework of architectural/urban planning for disaster risk reduction.
