Two of the most predominant characteristics of Surface Wave are Dispersion and Attenuation which are the effective tools to study the velocity structure and viscidity structure of the earth interior.
Under the circumstance of seismic long wavelength, the circular dry fracture is more effective in attenuation of elastic wave than thin dry fracture when the characteristic scale is same.
