Hirochika Sumino (dark green jacket), Tomoya Obase (blue jacket) and Hiroshi Shinohara (orange jacket) collect gas samples from fumaroles in Tateyama Jigokudani (“Hell Valley”) geothermal area, in Toyama Prefecture, Japan. Collecting gas samples from fumaroles is dangerous due to the toxic gas and hot steam, so a gas mask, goggles, helmet and gloves are required. But Sumino says the results of this study show that the insight obtained from the samples is well worth the challenge.
