Description
Nomi Bay in Susaki, Kochi Prefecture, has experienced numerous earthquakes in the past. The oral tradition of Kurodagori, a coastal village submerged under seawater due to the Hakuho Earthquake in684AD, is well known in this area. Since no scientific evidence of Kuroda-gori has been presented to date, a seafloor survey of Nomi Bay was undertaken to locate the footprint of the submerged village. The results revealed the existence of a plateau at a depth of6m to7m measuring 0.09km2 that sloped gently toward deeper water in the northeastern part of Heshima Island. The site was previously reported to contain the ruins of a freshwater well. The seafloor in the platform was mainly covered with a thin sand layer, with the amount of gravelly substrates increasing toward the shore. The sand layer is considered to overlie hard basement rocks. These topographic and geological features are consistent with a wave-cut platform. Based on relative sea level changes and vertical coseismic movements, the former platform was probably submerged by the Nankai earthquake. This submarine platform may have been
