In the Kunisaki peninsula, you can observe the bluff of Kunisaki Andesite along the coast.
In the center part of the strata, you can see the platy joint, which was created when the lava touched the sea water and produced cracks due to the sudden contraction.
The strata of debris flow beneath the lava flow were burnt by the hot lava vlow, and its color was changed to red.
* The ground condition of this area is unsteady and there is a risk of rock falls, so please be careful during the observation.
