Cross-sectional resistivity structure along survey line Fa: a 2018 survey, b 2008 survey, and c resistivity change in log (R2018–R2008). P indicates the resistive portion within Layer II, which is considered a vapor pocket. U indicates a possible upwelling of hot springs from Layer II. See text for a more detailed interpretation of P and U
