Geodynamics is the associated field of geophysics which deals with the earth dynamics in combination with fields of mathematics and chemistry. Geodynamics generally use data from geodetic GPS, InSAR, and seismology.
Geodynamics has impact on all areas related to Geosciences, Environment, Natural Disaster, Mining and Urban Planning. Fundamentals of geodynamics are continuum mechanics, heat flow, chemical thermodynamics, and rheology.
Mathematics is the central tool used to apply physical theories and create predictive models of the Earth.
