This paper examines the characteristics of channel wave propagation in a waveguide formed by two parallel fractures using two-dimensional elastic finite difference simulation and mode analysis. Velocity dispersion of the fracture channel waves computed from f-k analysis of the synthetic waveforms shows good agreement with the mode solution. The dispersion characteristics of the fracture channel waves are compared to those for classic Rayleigh channel waves in a low velocity layer withdoi:10.1190/1.1820232 fatcat:esgokxjblzee5eybeg3evvnz6q
