[1] Granada (Southern Spain) is a place of rare and enigmatic very deep focus earthquakes, the last one on April 11, 2010, with magnitude of 6.3 and depth of 620 km. We use regional broadband recordings to estimate Q P and Q S in the mantle for frequencies between 0.25 and 8 Hz, computing the spectra of the direct P-and S-waves with their early P-and S coda. We use the spectral decay method, constraining crustal Q to values given in the literature. We obtain robust estimates of Q P in 6 frequency bands (0.25, 0.5,1, 2, 4 and 8 Hz) and of Q S in 4 bands (0.25, 0.5,1, 2 Hz). Q P in the mantle ranges from 13 at 0.25 Hz to 346 at 8 Hz and Q S from 59 at 0.25 to 183 at 2 Hz. The frequency dependence is well fitted by Q = Q 0 f a with a equal to 0.6 for Q S and 1.0 for Q P , and Q 0 equal to 109 for Q S and 63 for Q P . The Q P /Q S ratio is less than 1. These are extreme values within the ranges of mantle Q, Q P /Q S and a values reported in the literature, indicating strong scattering attenuation and absence of melt. We propose that such values, rather than being an exception, may approximate the average upper mantle, with solid olivine composition and small-scale heterogeneity.
