Oscillation condition diagrams for magma (\(\rho =2800\) kg/m\(^3\), \(\eta =5\) Pa s). The parameter R determining the tremor condition, the oscillation frequency, f, and the channel volume, \(V_0=L\alpha _0\), are shown from the top to the bottom as functions of the driving pressure, \(p_1\), and either of the crack length, L (a), the channel elasticity coefficient, \(K_c\) (b), and the minor half width of the channel cross section, \(a_0\) (c). In each frame, all the parameters except those on the axes are fixed at the values in Table 1
