Red Cliff Sekiheki

Red Cliff Sekiheki

Sekiheki is a large, colourful cliff almost 1k long on the south coast of Chiburi Island, Chiburijima.

Chiburijima is the southernmost, smallest, and least-popu lated of the 4 inhabited islands of the group of islands known as Oki off the coast of Shomane.

The Oki Islands are part of the Daisen-Oki National Park, and since 2013 have also been a UNESCO Global Geopark.

Geoparks tend to focus on the geology of a place and also tend to have a lot of signage and information boards explaining what you can see.

Sekiheki is a great spot to see the result of various volcanic activities 6 million years ago. The Oki islands themselves are a sunken caldera.

The sections of cliff that are red were formed from magma with a high concentration of iron-oxide.

The Oki Islands are one of my favorite three places in Japan and other posts from them can be found by clicking this link.
