SW Pacific and Japan have similar tectonic settings and volcanism. We face common risks from local and widespread impacts of eruptions, particularly those interacting with surface water. The January 2022 eruption of Hunga-Tonga Hunga-Ha’apai (HTHH) in Tonga generated tsunamis that affected not only Tonga but also Fiji, Vanuatu, and Japan unexpectedly. This incident has revealed that an eruption can cause widespread disasters and that our awareness, preparedness, and technology are insufficient to reduce the risk of such events.

We are going to start the SATREPS (Science and Technology Research Partnership for Sustainable Development), funded by JICA (Japan International Cooperation Agency) and JST (Japan Science and Technology Agency) from April 2024 for five years. The project aims to establish the foundation to reduce the risk of widespread eruption disasters from oceanic and island volcanoes in Fiji, Tonga, and Vanuatu through geological and geo-structural surveys to update/develop hazard maps for eruptions and tsunamis, three-country collaboration for monitoring and responses to eruptions, and university educations in science and technology related to volcanology. We will elaborate on making the project research outcomes practically useful and sustainable through inter-organization collaborations, including such institutes engaged in disaster response, meteorological monitoring and warning, and university education. Collaborations with related organizations and researchers from South Pacific Countries and Worldwide are essential to make the project successful.

This presentation will introduce the project structure and ongoing collaborations.
