Title: Toroidal mantle flow around the Calabrian slab (Italy) from SKS splitting
Series/Report no.: 31/10(2004)
Issue Date: 2004
DOI: 10.1029/2004GL019607
Keywords: SKS splitting
Abstract: SKS-wave birefringence is likely caused by ongoing and/or fossil mantle flow. Splitting parameters in the southern Tyrrhenian subduction zone define a quite complex pattern of fast directions with large delay times up to 2.7 s. Fast directions are prevalently trench parallel below the slab and rotate to trench normal at the western edge of the slab depicting a ring around it. We interpret these anisotropic patterns, also observed in laboratory experiment, as toroidal mantle flow induced by rollback subduction.
