Aiming to Create the Safer and Less
Vulnerable Cities with Minimum Environmental Impact by Disasters..Risk Assessment Research Department

Research Activities
Quantitative assessments of urban functions and living environments against natural disasters such as earthquakes, tsunamis and heavy rains, as well as measures for disaster prevention and mitigation, are studied inter-disciplinarily . Our aim is the establishment of a scenario map toward the creation or reconstruction of secure and safe urban cities by studying generation mechanism of earthquakes, identification and quantification for disaster risk against strong ground motions and tsunamis, and academic approaches to measures to improve safe environments with a focus on disaster prevention and mitigation.
