Gravimetry allows us to study sub-surface structures remotely by measuring changes in Earth's surface gravitational field and using this data to infer the density of geological structures. Of its wide range of applications, it is mostly used in the o

By measuring tiny variations in the Earth’s gravitational acceleration, g, one can infer density variations beneath the ground. Since magmatic systems contain rock of differing density, changes in gravity over time can tell us when/where magma is m

Gravimetry is the only method able to directly track redistributions of bulk masses. Hence, it can supply unique information on geophysical processes that involve subsurface fluids like water, hydrocarbons, and magma. Nevertheless, the high cost of c
