Seismic anisotropy, the variation in seismic wave speeds depending on direction, is a well-documented phenomenon in Earth's interior. This characteristic is especially prevalent in subduction zones.
Research indicates that hydrous mantle minerals could be a key factor contributing to this anisotropic behavior. Their presence may influence how seismic waves travel through these geological formations.
These findings could enhance our understanding of the dynamics within stagnant slabs and their impact on seismic activity, providing valuable insights for geoscientists studying Earth's complex interior.
