It is shown that in the layered media with weakened interfaces the resonance waves ($Kr$-waves) are arose. Such waves have the very characteristic frequencies and a lot of other cinematic and dynamic features distinguish them from the well-known Love and Rayleigh type waves. The comparison of the theoretical results with experimental seismic data indicates that $Kr$-waves can be formed in the real geological section. We show theoretically and numerically that in a sedimentary basin of finite lateral extent horizontal $Kr$-wave can be trapped and resonate. This wave has a number of interesting properties: wave spectrum has resonance frequency; wave group velocity is equal to an intermediate value between shear and longitudinal velocities; attenuation of wave increases when the frequency varies from the resonance value.
