Conclusions

Our passive dataset contains some interesting plane wave energy. The weak but abundant near-vertically incident events are surprising, but their origin remains a mystery. The quarry blasts show evidence of multiple propagation paths or scattering in their coda which merits more careful investigation.

Looking for scattered energy in the dataset is hampered by the fact that plane wave energy seems so strong that it overwhelms any scattered energy present. Some sort of filtering in velocity space can hopefully remove the plane wave energy and make scattered energy more apparent.
