日御碕の地形


日御碕には、高さ25mと34mの2つの海岸段丘が非常に高い場所にあります。日御碕灯台は下段の海岸段丘の上に立っており、上段の段丘には駐車場があります。これらの段丘は、海がこの高さまで達していた、約20万年前から10万年前に形成され、波と海水が海岸を削り、浸食して、その結果平面になったと考えられています。


日御碕一帯はかつて10~15mの厚さの風化した土に覆われていました。しかし季節風によるはげしい波しぶきを受けやすい西側では土壌は削り取られ、今日では岩盤層を見ることができます。

Topography of Cape Hinomisaki


Cape Hinomisaki is made up of two lofty coastal terraces, at heights of 25 m and 34 m. The Hinomisaki Lighthouse stands on the lower terrace, and there is a parking lot on the upper. These terraces are thought to have been formed underwater between about 200,000 and 100,000 years ago, when the sea level was much higher than today. Waves scraped and flattened the seabed, which was then exposed to form the level terraces we see today.


A 10–15 m thick layer of weathered soil once covered the Cape Hinomisaki area. However, powerful waves driven by harsh seasonal winds have stripped away the soil on the western side, exposing the underlying bedrock.
