Buried Alive: Imaging the 9 November 2022, Mw 5.5 Earthquake Source on the Offshore Adriatic Blind Thrust Front of the Northern Apennines (Italy)

The prompt identification of faults responsible for moderate-to-large earthquakes is fundamental understanding the likelihood further, potentially damaging events. This increasingly challenging when activated fault an offshore buried thrust, where neither coseismic surface ruptures nor GPS/InSAR deformation data are available after earthquake. We show that on 9 November 2022, Mw 5.5 earthquake Pesaro ruptured a portion Northern Apennines thrust front (the Cornelia system [CTS]). By post-processing and interpreting seismic reflection profiles crossing this system, we determined (CTS) arcuate 30-km-long, NW-SE striking, SW dipping older structures at its footwall possibly influenced position geometry. activation adjacent segments plausible scenario deserves to be further investigated understand full potential seismogenic source.
