Session 1.1 GNGTS 2024 Furthermore, the projecton of earthquakes onto an E-W cross-secton identfed a seismic gap on the Kalabsha Fault, suggestng a locked fault patch approximately 11 km in length. According to Wells and Coppersmith (1994), such a segment could potentally trigger an earthquake with a magnitude up to Mw=5.9 in the event of a single rupture. Additonally, an earthquake clustering analysis revealed two clusters with prolonged swarm actvity, driven by pore pressure difusion, and four clusters characterized by seismic sequences and repeated earthquakes.
