Abstract

<p>We review the timing, mode, and topographic development of the Ryukyu Arc from the viewpoint of Quaternary crustal deformation. We also discuss the uplift and subsidence trends of the island region of the Ryukyu Arc, and the timing and mechanism of formation of depressions (Tokara Tectonic Strait, Kerama Gap, and Yonaguni Depression) that divide the island region of the Ryukyu Arc. The strikes of normal faults in the Tokara Tectonic Strait and Kerama Gap differ from those in the Yonaguni Depression. The timing of uplift and subsidence is spatially variable throughout the island region of the Ryukyu Arc. Future work will focus on neotectonics, geomorphic processes and landform development in the context of neotectonics, and the ongoing tectonic evolution of the island arc.</p>
