Description
Book SynopsisHead waves – also called refraction arrivals, lateral waves, or conical waves – have been used extensively in near-earthquake studies, geophysical prospecting, and deep-crustal seismological investigations. In the past, research was confined largely to the kinematic characteristics of the waves, but emphasis is now being given to the dynamic characteristics: amplitudes, spectra, and wave forms. In the last fifteen years, several new mathematical and computational techniques have been developed to study these waves.
This is an advanced, technical book presenting a consistent theory of head waves, using methods developed in the famous Leningrad school under G.I. Petrashen and his colleagues. It proceeds from a consideration of the simplest problem of one interface to a study of the situation in which there are many interfaces (some of which may not be plane or parallel to one another) and the material between the interfaces is not necessarily homogenous. The method i
