Abstract

River terraces are well preserved in the middle to lower reaches of the Hishida River, that flows through the extensive ignimbrite field produced by the large-scale Ito eruption about 24,500 years ago from Aira caldera in southern Kyushu. High erodibility of the non-welded Ito ignimbrite and absence of vegetation on the initial surface would have permitted a rapid dissection of the initial topography and the formation of the river terraces. Thus, it is interpreted that the river terraces were formed very rapidly in a period of far less than 1500 years immediately after the deposition of the Ito ignimbrite and before cover of new vegetation on the depositional surface
