Asymptotic Theory of the Earth’s Normal Modes

  • 642 Accesses

Abstract

We have seen that the complete seismic field induced in a radially heterogeneous sphere can be expressed as an infinite sum of standing waves, namely the normal modes. However, we know from seismogram analysis that most of the recorded earth motion can be explained in terms of propagating waves. There must exist a link, therefore, between these two seemingly different aspects of wave motion.

After having spent years trying to be accurate, we must spend as many more in discovering when and how to be inaccurate.
