Joint analysis of geological, geophysical and petrological data shows
that the feeding mechanisms beneath volcanoes may be very complex.
This is evidenced by the strong spatial variations in composition and
eruptive style that can exist even within tightly clustered groups of
volcanoes
is not definitively proven. Popular Hollywood movies may present
scenarios showing the temporal evolution of real-time 3D images of
bodies beneath volcanoes, but unfortunately, the real capabilities of
the present-day science are far more limited.
