紺屋地獄— “Dyer’s-Vat Hell”
日本は、地獄と名のついた湯気が立ちのぼる火山の谷あいや湿地であふれています。この紺屋地獄という紺屋の染物桶のような形の湯気の立つ泥の沼は、94℃の熱湯です。
この沼の泥は、地面の噴気孔から逃げる蒸気中の硫黄が地面に移動し、硫化鉄の沈殿が生じる際にできます。この沈殿は、劣化した岩石と合わさって泥になります。表面を注意深く見ると、蒸気の力で泥が泡立っているのが見えるかもしれません。

Kon-ya Jigoku - “Dyer’s Vat Hell”
Japan is full of steaming volcanic valleys and marshlands called jigoku, or “hells.” The Kon-ya Jigoku, a steaming pond of mud that is shaped like a kon-ya, or dyer’s, vat, is a blistering 94°C.
The mud in the pond is formed when sulfur in the steam escaping from vents in the ground travels to the earth’s surface, forming iron sulfide sediment. The sediment then combines with deteriorated rock to form mud. Careful observation of the surface may reveal the mud bubbling from the force of the steam.
