Uncertainty associated with the geometry of the rupture plane of a seismic event is a critical issue that is often overlooked in seismic hazard assessment. After damaging earthquakes, identifying the geometry of the rupture plane is not a trivial task. Significantly different geometries can be obtained depending on the specific technique (e.g. finite-fault inversion, source scaling with CMT solution, geodetic observations) used. The results related to 2020 Samos Earthquake indicate that median ground motion intensities vary up to 60% depending on the assumed geometry and the relative location of the site of interest.
