This project conducts comprehensive research on earthquake and tsunami disaster mitigation in Peru in the framework of "Science and Technology Research Partnership for Sustainable Development (SATREPS)," sponsored by Japan Science and Technology Agency (JST) and Japan International Cooperation Agency (JICA). The project focuses on five research fields, i.e., seismic motion and geotechnical, tsunami, buildings, damage assessment, and disaster mitigation planning. Almost three years have passed since the five-year project started in March 2010. During this period, researchers in different fields from Japan and Peru collaborate to achieve the overall objectives of the project. This paper summarizes the research framework and progress of the JST-JICA project on earthquake and tsunami disaster mitigation technology in Peru.
