Title: Seismic imaging of slab segmentation and correlation with volcano distribution along the Aleutian-Alaska subduction zone

Abstract: The along-strike variation (segmentation) of downgoing slabs and surface volcanic activity has been observed globally. However, the influence of slab segmentation on volcano distribution is poorly understood. The diverse magmatism and the presence of volcanic gaps make the Aleutian-Alaska subduction zone an ideal place to investigate this question. Using full-wave ambient noise tomography, we present a high-resolution shear-wave velocity model in Aleutian/Alaska. The new model reveals a distinct high-velocity Pacific slab along the Aleutian arc, subducting at a steeper angle than the Yakutat slab beneath southcentral Alaska. The change in slab geometry and mantle wedge velocities correlate with the non-uniform distribution of volcanic activities. In contrast to the back-arc and forearc low velocities within the Aleutian mantle wedge, the seismically fast mantle wedge beneath the Denali volcanic gap may indicate the lack of melt. Our findings provide direct evidence for the correlation between slab segmentation and magmatism at subduction zones.
