Viscoelastic seismic modeling and Q estimation for an attenuating media

In seismic modelling experiments, the propagating seismic wave experiences attenuation when real media is simulated. However, for computational ease, we often ignore this effect and model the Earth as either an acoustic or an elastic medium. In this paper, we briefly discuss the importance of considering attenuation in seismic modelling, by using a viscoelastic wave equation. Further we also briefly discuss the effects of attenuation on seismic data and its incorporation in seismic modelling. We find that the attenuation has a large effect on synthetic seismogram, which should be properly addressed in advanced seismic processing and imaging methods.
