Relationship between \(\kappa _\text{ch}\) and \(n_\mathrm {H_{2}O}^0\) for the observed values of \(\Delta V_\text{E}/\Delta V_\text{G}\) during the 2011 (2.69; solid curves) and 2018 (2.33; dashed curves) eruptions, with varying p (150 and 300 MPa) and \(\rho _\text{e}\) (1500 (a), 2000 (b), and 2500 (c) kg m\(^{-3}\)). The results are obtained from Eq. (7), where \(n_\mathrm {CO_{2}}^0\) is set as 0.25 wt%
