この洞窟は溶岩でできています。まだ溶岩が熱い液体状のマグマの中に空間ができ、その中にガスがたまり、圧縮されてガス爆発を起こし溶岩洞窟ができあがりました。
In the past August, we had no private tours as so much busy season. This isn't a private tour so that we are introducing the group tour at this time. We are encouraged you to join the tour together with other customers.
We appreciate your cooperation.
This cave was formed by the lava.
There's a space inside the liquid magma with lava at extreme hot temperature, it concentrates the gas in it. The lava cave was formed with the result of gas explosion pressured.
