Abstract: Processes and systems for microseismic event detection. In some embodiments, the process can include acquiring seismic data with a dense seismic receiver array; converting seismic data into an image domain dataset; detecting one or more seismic waveform edges; characterizing within the image domain dataset one or more linear segments which each define a portion of one or more of the one or more seismic waveform edges, and wherein the linear segments are functions of one or more seismic arrival times and one or more subterranean depths; and estimating the subterranean depth of the one or more microseismic events within a subterranean formation based on the one or more linear segments.
