Magma chambers that produce supervolcanoes can be detected and imaged using geophysical methods.
Geophysical techniques such as seismic tomography and geodetic measurements are well-established methods capable of imaging and detecting the subsurface magma chambers associated with supervolcanoes.
The provided literature clearly supports the claim that magma chambers associated with supervolcanoes and large magmatic systems can be detected and imaged using geophysical methods like seismic tomography and geodetic surveys.

High-enthalpy Larderello geothermal system, Italy, powered by thousands of cubic kilometres of mid-crustal magma.. 2026. https://doi.org/10.1038/s43247-026-03334-0
Subsurface geophysical and geological data revealed thousands of cubic kilometers of crustal magma fueling the Larderello system, comparable to mid-crust reservoirs beneath recognized supervolcanoes.
