Definitions:

Gravity Survey

A geophysical method for measuring variations in the Earth's gravitational field, which can indicate differences in the distribution of densities and hence the structure of the subsurface.

Plate Boundaries

The edges where two or more of Earth's tectonic plates meet, often associated with seismic and volcanic activities.

Fault Systems

Networks of fractures in the Earth's crust along which displacement has occurred, important in understanding the movement of Earth's tectonic plates.

Volcanic Activity

Refers to the eruption of magma from beneath the Earth's crust, forming igneous rocks and often creating mountains or craters.
