Fig. 4

Computed Q factor of the solid mantle of Earth for the 12.42-h tidal period using the synthetic profile displayed in Fig. 3 for various values of viscosity for the lower high-pressure (HP) mantle, ηHP (with ηLP∕ηHP = 100) and of α parameter for the Andrade rheological model. The bold black line indicates the estimated value of Q for the interior of Earth and the gray area shows the uncertainty range estimated by Ray et al. (2001).
