From: Automated microseismic event location using Master-Event Waveform Stacking
(Panel a) Seismic event recorded by a line of receiver deployed on the surface (a.1), raw (a.2) and processed (a.3) traces. (Panel b) waveform stacking is performed by scanning different source locations (b.1, b.2, b.3) and different origin times (c.1, c.2, c.3)). (Panel c) The output of the location process is a multidimensional coherence matrix (d.1, d.2, d.3) whose maximum corresponds with the hypocenter and the origin time t0 of the seismic event (d.2).
