Tidal deformations of the solid earth show remarkable regional fluctuations. Mean gravity anomalies reveal strong positive correlation with the regional variations in the vertical tide component, if the effect of topography on the gravity field is reduced by isostatic proceedings. The correlation of these “tidal anomalies” with the lower harmonics of the gravity field is weaker. Heterogenities of the upper mantle may be a source of these differences in the deformations.
