Seismic Surface Waves in a Laterally Inhomogeneous Earth

Surface waves form the longest and strongest portion of a seismic record excited by explosions and shallow earthquakes. Traversing areas with diverse geologic structures, they ''absorb'' information on the properties of these areas which is best retlected in dispersion, the dependence of velocity on frequency. The other prop­ erties of these waves - polarization, frequency content, attenuation, az...
