Estimating the effective elastic thickness of the lithosphere of the Iberian peninsula based on multitaper spectral analysis

Effective elastic thickness of the lithosphere of the Iberian peninsula was estimated from a coherence analysis of topography and gravity spectra, for which a multitaper technique was used. Coherence estimates provide an average T e value of 17 ± 4 km. To verify the T e derived from the spectral analysis, we compare it to independent T e estimates from strength envelopes constructed for some tecto...
