AB: When seismic waves interact with strong heterogeneity in the Earth, multiple scattering makes deterministic imaging a challenge. Instead, seismologists often resort to the retrieval of statistical inferences about subsurface properties by investigating the evolution of the squared wave field, or energy. Recent investigations in some of the strongest scattering regions of the Earth's subsurface indicate that these diffusion-based or radiative transfer- type models for energy propagation may not hold. This is because these models do not incorporate wave interference terms. We present a modification of radiative transfer theory to include the effects of wave interference. This modification aims to improve statistical inferences about velocity and attenuation of those regions of the subsurface where scattering Q drops into the single digits.
