Kushima island and Suzushima island

The angular unconformity of the Muro strata and the Kumano strata can be observed on the south side shore platform. You can see traces of lugworm colonies which suggests the land’s elevation on the Suzu-shima island on the north side. Kushima island is a breeding area of one of the world’s rarest bird, the Styan’s Grasshopper Warbler.
