\(\Delta V_\text{E}/\Delta V_\text{G}\) as a function of initial H\(_2\)O content (\(n_\mathrm {H_{2}O}^0\)) with varying initial CO\(_2\) content (\(n_\mathrm {CO_{2}}^0\)) obtained from Eq. (7) or (9). The compressibility of the magma chamber (\(\kappa _\text{ch}\)), pressure (p), and density of the erupted magma (\(\rho _\text{e}\)) are set to \(5 \times 10^{-10}\) Pa\(^{-1}\), 245 MPa, and 2500 kg m\(^{-3}\), respectively
