Have you considered the effect of the electric field in causing dethermalization? You have discussed the effect of temperature on the speed of sound,but with dethermalization, it is a bit different. Instead of changing the speed of sound uniformly in all directions (as with just a temperature change), dethermalization can cause an increase in speed of sound in one dimension, while decreasing the speed of sound in others. Specifically,in your model of charge separation, we would have a higher speed of sound up and down through the charge separated layer,than we do across that layer. Would that not cause a refraction of seismic waves at those boundaries?
I'm not familiar with the seismic data. Does it support refraction in this direction? Again, since and electric field takes all that random motion (temperature),and gets it moving along field lines, it works like an increase in temperature along the field lines (as far as increasing the speed of sound), and an effective temperature decrease in the transverse directions (decreasing sound speed)
I don't know if this helps? It does seem that we could explain significant refraction by having a sudden increase in speed of sound direction up through your charge separated layers (lower across it), with a more uniform spread of sound elsewhere?
