GADRI aims to serve as an advocacy organization to speak with one voice in an effort to influence decision-making processes. The purpose of this session is to discuss next step of large-scale research facilities supported by research communities. Large-scale experiments, along with numerical simulations, are major tools for clarifying phenomena in disaster prevention research. For example, in earthquake research, the usefulness of large-scale shaking tables has been demonstrated. In this session, large scale experimental apparatuses, instruments, observational facilities, and computational environment to promote research and development on disaster prevention is discussed. Discussion about what kind of experimental instruments and facilities are necessary for future disaster prevention research and science, and how to utilize them. Furthermore, the utilization of these large-scale facilities, such as joint use, is discussed from the perspective of the disaster research community.
