It has recently been shown that the recovery of the Green function can be performed from seismic noise. This function is the fundamental characteristic of the medium where seismic waves propagate. In this work a 2D formulation is proposed which allows the recovery of the Green function from seismic noise. Several homogenous media characterized by their propagation velocities and Poisson ratio are studied. In addition, for the two-dimensional case, where only P and SV waves are propagated, the energy contributions corresponding to each type of seismic wave are discussed and verified.
