FWEA18 Earth model represents a full waveform inversion model for East Asia.
|Title||Full waveform inversion of East Asia|
|Type||3-D Tomography Earth Model|
|Sub Type||Radial anisotropic (in the uppermost mantle) P and S velocities|
|Short Description||In this model, radial anisotropy is confined to the uppermost mantle (above 220 km). 1D Qmu model is fixed to QL6 (Durek & Ekström, 1996). All velocities are at 1 Hz.|

|Depth Coverage||Upper Mantle (0 to 800 km)|
|Areal Coverage||East Asia (N10°/60°, E90°/150°)|
|Data Set Description||[ Tao et al. (2018) ] A total of 95 earthquakes and 1590 seismographic stations were used in this study. The final dataset is comprised of ~1.35 million body wave windows (10 – 100 sec) and ~72 thousand surface wave traces (40 – 100sec).|
