Abstract
Huygens's principle is used to derive a method for calculating first a rrival traveltimes in anisotropic media. Numerical results for several transverse isotropic (TI) models show that calculated Huygens travelt imes are in good agreement with traveltimes computed by a finite-diffe rence solution to the anisotropic wave equation. This Huygens method i s stable and accurate for the test models and so it may be useful in a nisotropic data inversion and wave propagation visualization.
