Fig. 9

Sequential change in the volcanic component of soil gas near the center of the 2015 eruption (Loc. 3 in Fig. 1c). The soil gas concentrations were measured by detector tubes. No pressure correction was applied. The durations of volcanic unrest episodes are shown as shaded yellow (VAL2 or more) and blue (baseline across the volcano is increasing). See caption of Fig. 3 for details
