Wave Propagation and Models for the Medium

  • Irina P. Kosminskaya

Abstract

With shooting at a single point and observation of the resultant seismic vibrations at many points, wave propagation may be described functionally as A = f (t, R), where A is the “intensity” of the vibration, t is time, and R represents the spatial coordinates x, y, and z. Here, A is.a value representing the amplitude of any wave (or part of it) under equivalent conditions. It is a scalar, vector, or tensor quantity: displacement, particle velocity, acceleration, pressure, stress, strain, and so on. In the simplest case, it may be assumed that A and R are scalar quantities, with A being the deflection on a record and R the distance from the shot point to the observation point.
