Description

In our current study “Radial and azimuthal anisotropy tomography of the NE Japan subduction zone: implications for the Pacific slab and mantle wedge dynamics,” we investigate slab and mantle structure of the NE Japan subduction zone from P wave azimuthal and radial anisotropy using travel-time tomography. In the analyses, we used arrival time data picked by NIED (National research Institute for Earth Science and Disaster Resilience). The picked data are currently NOT available. However, the original waveforms are free to download from following website (https://hinetwww11.bosai.go.jp/auth/download/cont/?LANG=en). Therefore, we show lists of earthquakes (original_event_list.txt) and seismic stations (staion_list.txt) used in our tomography analyses to replicate work on our current anisotropic tomography analyses. Also, we show ASCII files of the resultant 3D azimuthal (AA.txt) and radial (RA.txt) anisotropic structures in our study. We describe P wave anisotropic velocity using parameters assigned to three-dimensional grid points set in the study area. FigS1b.pdf shows the three-dimensional grid configuration. Grid-location.xlsx provides the location of the grid points.
