Figure 4.

Figure 4.

Conceptual model of the coalescence of magma bodies and their viscoelastic aureoles, and the influence on surface deformation. Solid lines show the instantaneous elastic deformation and the dashed lines show the integrated deformation over the longer term, including the viscoelastic response. Numerical models (figure 7) show that stage 4 is rarely achievable at realistic magma fluxes. (Online version in colour.)
