Seismic Imaging of the Westward Transition From Yakutat to Pacific Subduction in Southern Alaska
Résumé
• We apply a multi-mode 3D Kirchhoff migration to a new composite seismic data set from six arrays deployed in Alaska from 2000 to 2018 • We observe a sharp lateral boundary in the slab structure with a 10 km Moho step just offshore Anchorage from the Pacific to the Yakutat slab • Our observations suggest that the crust is still partially uneclogitized down to 150 km depth in both slabs
