The subduction channel is a concept to explain certain phenomena observed by geoscientists around subduciton zones. Although many theories concering this have been formulated, the proof of the existence of such a channel is still open. We use homogenization techniques for wave propagation properties of the material to account for the microstrucural effects on seismic waves in such a supposed subduction channel. In order to assist the search for it we want to reveal the effects that it would have on elastic waves propagating in the crust, which are observed via surface measurement.
