Seismic moment tensors of earthquakes in anisotropic media have more complicated properties than in isotropic media. For example. planar shear faulting produces pure double-couple mechanism in isotropy, but generally non-double-couple mechanism in anisotropy. The effects of anisotropy on moment tensors are numerically modelled and exemplified on acoustic emissions measured in the lab, on microearthquakes in the upper crust and on large deep-focus earthquakes in the Tonga subducting slab.
