Fumaroles on active dangerous volcano near Tohya lake in southwestern Hokkaido. A new parasitic cone, Showa-shinzan, erupted dacite lava from the southeast flank of Usu-zan in 1944-1945, emitting very high-temperature steam (over 800 C) consisting of water vapor, hydrogen, HF, HCl and boric acid. Fumarole gases here have the highest concentration of tin vapour (7 ppm) of any volcano (Giggenbach & Matsuo, 1991).
