説明
This study discusses the Holocene landscape evolution of the Kimotsuki River basin, Osumi Peninsula, Southern Kyushu Volcanic Field, Japan, with reference to volcanic events. The type stratigraphy of alluvial deposits in lower reaches is constructed by synthetic analyses about the Kushira-yoshimotobashi core. While most hillslopes were stabilized by 6.5 ^<14>C ka and sediment supply from upstream areas was reduced, leading to the widespread deposition of peat layers in the late Holocene, the Holocene transgression resulted in coastal erosion along the cliffs of the non-welded A-Ito ignimbrite and so sediment production in coastal zones increased during 7-5 ^<14>C ka. In addition, K-Ah and Ik-P tephras which fell in the mid-Holocene were re-transported to the lowland. These deposits contributed to infilling of the inner bay and lagoons. The past major volcanic eruptions affected land surface environments discontinuously and episodically, lasting for relatively short periods, although they played important roles in sediment supply. They are thus an abrupt and brief driving force for landscape evolution.
