From: Automated microseismic event location using Master-Event Waveform Stacking
Panel (a.1) shows the master event (its location is supposed to be known) and the target event to be located. We then calculate the theoretical traveltimes of the master event, for a given velocity model (panel a.2) and we compute the correction term for each station (panel b). Panel (c.1) represents the master-event WS process using the corrected traveltimes (continuous lines). With respect to the standard WS the coherence obtained by using this approach is higher (panel c.2).
