Lehmann discontinuity and shear wave anisotropy

  1. Jan 29, 2007 #1
    What do geophysicists mean by depth variation in the shear wave anisotropy of the Lehman discontinuity? And why is there none under the oceans but some under the continents?

    you seem to have a new question every five minutes.

    anisotropy basically means that the waves travel faster in different directions. shear waves (or s-waves) are a type of seismic wave, there are twoo types of elastic wave, siwaves are slower than p-waves.
    s-wave anisotropy has something to do with the speed s-waves travel at different angles (like they might travel faster going sideways than going upwards for example).
