“…The focal mechanism solutions in the Gulf of Aqaba are intensely studied by several authors 11 – 13 , 15 , 17 – 29 . These studies revealed a variety of fault types, including normal faults, strike-slip faults, and oblique-slip faults, reflecting the complexity of the structure in the Gulf of Aqaba, These solutions demonstrated that the main fault trends in the Gulf of Aqaba are confined to the NNE–SSW, which primarily represents the left lateral strike-slip motion that is parallel to the Gulf while the NW–SE and the WNW–ESE fault trends represent the normal dip-slip motion that is distributed along the Gulf basins margin.…”

The Gulf of Aqaba is known for its high seismic activity in Egypt and the Middle East. An inversion technique was applied to 113 earthquakes of magnitude 2.5 to 7.2 to distinct subsets of data based on tectonic regionalization to define the stress regime in the Gulf of Aqaba involving the Eilat basin, Aragonese basin, and Dakar basin. The stress inversion revealed two active stress patterns; an active strike-slip in the Eilat basin and a dominant extensional regime in the Dakar basin, whereas both strike-slip and extensional regimes coexist in the Aragonese basin. The stress pattern in the Eilat basin is consistent with the movement along the Dead Sea Transform Fault. In contrast, the extensional regime in the Dakar basin aligns with the extensional stress field throughout the northern Red Sea. The coexistence of two dominant types of stress regimes in the Aragonese basin is likely a result of the superposition of the two main neighbouring stress regimes: the strike-slip regime along the Gulf of Aqaba Dead Sea Transform Fault and the extensional stress state across the northern Red Sea. The orientations of the minimum principal stress in the three basins are almost similar, indicating ENE trending, nearly horizontal extension.
