Figure 2From: Imaging the hydrothermal system beneath the Jigokudani valley, Tateyama volcano, Japan: implications for structures controlling repeated phreatic eruptions from an audio-frequency magnetotelluric survey Apparent resistivity and impedance phase. Apparent resistivity (upper panel: app. res.) and impedance phase (lower panel: phase) observed at all the sites in the study area. Impedance tensor (ZXY and ZYX) off-diagonal components are shown in red and blue, respectively.Back to article page
