P-wave anisotropy tomography of central Japan: Insight into subduction dynamics

Within oceanic lithosphere a fossilised fabric is often preserved originating 15 from the time of plate formation. Such fabric is thought to form at the mid-ocean 16 ridge when olivine crystals align with the direction of plate spreading 1,2 . It is 17 unclear, however, whether this fossil fabric is preserved within slabs during 18 subduction or over-printed by subduction-induced deformation. The alignment of 19 olivine crystals, such as within fossil fabrics, can generate anisotropy that is sensed 20 by passing seismic waves. Seismic anisotropy is therefore a useful tool for 21 investigating the dynamics of subduction zones, but it has so far proven difficult to 22 observe the anisotropic properties of the subducted slab itself. Here we analyse 23
