“…Its differences with respect to conventional exploration seismology mainly consist of the absence of a controlled source, but also of distinct array geometries, continuous recording times, and low signal-to-noise ratios (S/Ns), among others. Although the source locations for passive seismic scenario are unknown a priori, one can apply imaging and inversion methods adapted from active source seismic scenarios to generate an image, showing the estimated source location, and/or to reconstruct a 3D earth model, with information about subsurface physical properties (Duncan and Eisner, 2010;Maxwell et al, 2010;Xuan and Sava, 2010;Behura et al, 2013;Blias and Grechka, 2013;Douma and Snieder, 2015;Witten and Shragge, 2015;Bazargani and Snieder, 2016;Shragge, 2017a, 2017b).…”
