here is the main result...


Velocity of compressional seismic waves in the lithosphere is presented as deviations from 1-dimensional velocity structure (IASPEI91). Colored surfaces enclose zones where deviation from 1D are over 3%, blue being fast and red being slow. This 3D distribution of velocity was obtained by inverting ~1000 measurements of travel time and ~120 measurements of polarization of the teleseismic P waves recorded by a local short-period network.
