| Research Abstract |
This study aims to observe prospects for sustainable development of atoll nations. Surveys were conducted for atoll islands on the response against tsunami, substrate geology and topography in Maldives in the Indian Ocean along with the topographic surveys in atoll nations in the Pacific (Republic of Marshall Islands, Kiribati and Tuvalu). We observed the structural strength of atoll and coral islands in contrast to the vulnerability of infrastructures on islands against tsunami. We also observed a large-scale underwater collapse of a reef wall at Male, the capital city of the Republic of Maldives. Our findings point out the importance of hard geological structure of Holocene reef with submarine cementation for substrate geology for atoll islands, and also a geohazard risk that may be common in seriously overpopulated coral cay cities around the world.
