This dataset is supplementary to Liu, C., Zhang, S., Sheehan, A. F., & Ritzwoller, M. H. (2022). Surface wave isotropic and azimuthally anisotropic dispersion across Alaska and the Alaska-Aleutian subduction zone. Journal of Geophysical Research: Solid Earth, 127, e2022JB024885. https://doi. org/10.1029/2022JB024885 This dataset contains two parts: 1) The composite surface wave dispersion maps, including Rayleigh wave isotropy and azimuthal anisotropy from 8 to 85 s both onshore and offshore, and onshore Love wave isotropy from 8 to 80 s on a 0.2°×0.1° grid.
