The rotation seismic waves become recently again a subject discussed from theoretical and observational points of view. Defects and internal structure contribute to processes of their generation and propagation. In theories of continua we can attribute generation of rotation waves due to defects of a disclination type or to micromorphic/micropolar structure of a source zone. However, these waves would become rapidly attenuated when propagating inside the continuum more close to that of ideal elasticity. Another possibility is provided by coupling between the seismic body waves and defects or micromorphic structures of medium just beneath an observation site; in this paper we discuss such a coupling in micro-inertia continua defined as the special cases of micromorphic/micropolar continuum.
