We carry out a two‐step procedure: (1) path effects are deconvolved from the seismograms using an empirical Green's function, resulting in relative source time functions at all seismic stations; (2) the relative source time functions are back‐projected to the corresponding isochrones on the fault plane. Results reveal that the mainshock rupture propagates toward NNE from the hypocenter with an average velocity of 2,000 m/s. Spatiotemporal organization of foreshocks and aftershocks shows that the mainshock broke a previously less active portion of the fault and suggests that the aftershock sequence could be mainly driven by stress transfer. Applying this method in an operational environment could enable fast retrieval of seismic slip, allowing assessment of fault asperities and structures involved in the reservoir creation process. date: 2019 date_type: published publication: Geophysical Research Letters volume: 46 number: 14 publisher: American Geophysical Union pagerange: 7990-7999 id_number: doi:10.1029/2019GL082911 issn: 0094-8276 official_url: https://doi.org/10.1029/2019GL082911 access_IS-EPOS: limited owner: Publisher citation: Király‐Proag, E. and Satriano, C. and Bernard, P. and Wiemer, S.
