Session 3.3 ______ ___ GNGTS 2023 epicentral area, standard location methods were not particularly successful for delineation of the seismic sequence. In this work, we show how the application of this new method for offshore seismic monitoring allowed us to achieve high location accuracy with just two onshore seismic stations. When compared to conventional locations our results are more clustered and clearly show a NW-SE alignment compatible with the geological setting of the area.
