Rapid formation of river terraces in non-welded ignimbrite along the Hishida River, Kyushu, Japan

Authors(s) and Affiliation(s)



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
