What information a seismologist is able to interpret from a seismogram. teleseisms. ), the waves of greatest amplitudes are generally surface waves that have followed the Earth’s surface and not penetrated the interior. The exceptions are seismograms of deep focus earthquakes, which are not effective generators of surface waves, so that the body waves are more prominent. The dominance of surface waves on .
