Quasi-static radiation forces, produced by ICRF waves, can modify tokamak equilibria by breaking the characteristic axisymmetry and producing magnetic island structures. The induced magnetic islands form about rational magnetic surfaces and magnetic axes of the unperturbed tokamak. In this paper, we present a perturbation analysis of a toroidal magnetohydrodynamic (MHD) plasma equilibrium that is under the influence of forces produced by low frequency waves. Conditions for magnetic island formation are derived.
