From: The dynamics of dual-magma-chamber system during volcanic eruptions inferred from physical modeling
Magma compressibilities in the deeper (\(\kappa _\text {m1}\); solid curves) and the shallower (\(\kappa _\text {m2}\); dashed curves) chambers (a), \(\kappa '\) for \(S_\text {c1} = S_\text {c2} = 1\) (b), and \(\kappa '\) with varying \(S_\text {c1}\) and \(S_\text {c2}\) (c), as a function of H\(_2\)O. The value of CO\(_2\) is varied from 500 to 2000 ppm in a and b and set as 500 ppm in c. See text for details
