Abstract Correct representation of seismic waveforms propagating through the mantle from a 600 km deep earthquake is presented using graphic interpolation between synthetic seismograms computed across a grid of mantle depths and distances. All torsional normal modes with periods above 12 s are summed to create 72,846 seismograms at depths between the surface and the core-mantle boundary. The resulting time snapshots show the manner by which seismic shear energy propagates around the core away from the source.
