The Hamiltonian formalism is applied to the treatment of the free motion of a three layered Earth model, where the effects of the pressure coupling, centrifugal deformation as well as gravitational and viscous-electromagnetic torques, are considered. Analytical expressions of the four normal modes of this dynamical system are derived.
