Geomorphic hazard along coastal plains in Central Ryukyus
(Amami Oh-shima and Okinawa Islands)
KIMURA, Kazuo

Abstract
This case study of the 1960 Chilean earthquake tsunami aims to show the relation between geomorphic characteristics and disaster intensity in Central Ryukyus, which are located in a sub-tropic island arc. The Amami Oh-sima Island is mainly surrounded by rias. Therefore, coastal plains such as Naze, Kominato, Sumiyo, Koniya are fragile for tsunami disasters. In northern part of Okinawa Island, submerged grabens form Taira Bay, Arime Bay, Oh-ura Bay, and offshore of Makiya and Nago areas. Geomorphic risk of those bays is similar to that of rias coast. Southern part of Okinawa Island was widely surrounded by fringing reefs in 1960. Those areas were less damaged by the tsunami in comparison with the above-mentioned regions. This shows that fringing reef is effective barrier for tsunami and similar coastal disasters. However, the highest tsunami in Central Ryukyus was also observed along a coast with coral reefs. In Kasari, which is north end of Amami Oh-shima, there are some apron reefs. The gap of apron reefs can concentrate tsunami energy, therefore, Kasari area was deeply inundated by the 1960 tsunami. Similarly, tsunami fluid concentrate to submerged valley. The wide inundation in Ishikawa of central Okinawa was caused by the effect of a submerged channel. During the last half-century, those coastal environments have been changed dramatically. Today, the most serious bottleneck for coastal disaster prevention is reclaimed lands. They have been eliminated fringing reefs, the guardian of costal life. They also produce tsunami-leading artificial channels.
