Short summary
When magma chambers inflate, they deform the surrounding Earth’s crust. This deformation affects the pore space available for the water in local aquifers, which in turn leads to pressure variations and water table changes. We can observe these changes in wells, and this study investigates if and how we can utilize them for volcano monitoring. Results show that the hydrological response to deformation helps unravelling subsurface magmatic processes, valuable information for eruption forecasting.
