We present a surface wave study aimed to resolve the azimuth‐dependent propagation velocities of Rayleigh waves (10–184s) in East Asia. The resultant anisotropy patterns demonstrate that East Asia consists of a number of tectonic domains, each displays a characteristic and self‐consistent deformation mode. The depth variation of the anisotropy pattern in each domain helps to understand the boundary actions on the lithosphere and the depth‐varying deformation styles owing to rheology change.
