“…Depending on previous studies [25,26], the predominant tectonic trends and structural styles, (as shown the rose diagram in Figure 2) are in NW and NE directions which well coincided with the results of the present work. Moreover, focal mechanism solutions and maximum shear analysis show that extensional strains and normal faulting are predominant in the Gulf of Suez province and compressional strains with left lateral strike slip styles prevail in the Gulf of Aqaba province [74][75][76][77][78].…”

Abstract:The aim of the present work is to evaluate the stress direction and the tectonic trends of the study area using magnetic anisotropy and potential field data interpretations (Bouguer and aeromagnetic). The specific objective of the gravity and aeromagnetic interpretation is to establish the trend and depth of the structural configuration of the basement rocks. Horizontal gradient techniques could to delineate directions of deep sources and enabled tracing several faults, lineaments and tectonic boundaries of basement rocks. The trend analysis shows N40°-50°W, N10°-20°W and N10°-20°E which may be related to the Gulf of Suez, Red Sea and Gulf of Aqaba stresses. However, Euler Deconvolution technique was applied using the aeromagnetic data to provide reliable information about penetrated source depth (100 m and ∼10.0 km) and trends of the subsurface sources (principally in NW and NE directions). Moreover, representative 72 oriented rock samples have been collected from seven sites in the study area. The rock magnetic properties and magnetic anisotropy analysis have been determined for all the studied samples. The interpretation clearly defined magnetic lineation at all sites and anisotropy of magnetic susceptibility (AMS) parameters. The stress direction of the studied area has been evaluated using magnetic anisotropy and geophysical analysis. Generally the estimated geophysical data analysis (Bouguer and aeromagnetic) are well consistent with the AMS interpretations of this study. The results indicated that the directions of predominant faults and foliations are NW-SE (related to the Gulf of Suez and Red Sea rifting) which indicate that the main stress and tectonic trend is NE-SW, which is more predominant in southern Sinai region. Moreover, it is clear that, the studied area was affected also by less predominant sources trended in NE-SW direction, which related to the tectonic activity of Gulf of Aqaba. The least predominant is north 40°-50°east that is probably due to the Syrian Arc system. Finally, our results are extremely coincided with the previous stress directions derived from geological, seismological and tectonic analysis in northern Red Sea rift, Gulf of Suez and Sinai regions.

“…Lartet (1869) interpreted the movement along the Dead Sea Rift to be strike-slip as the major movement and normal as a minor one. This interpretation was subsequently supported by Quennel (1956 and, Freund (1965), Freund (1966 and1981), Freund et al (1968 and, Neev (1975), Bartov et al (1980), Garfunkel (1981) and Garfunkel et al (1981). Others (Vorman, 1961;Michelson, 1982;Bahat and Rabinovitch, 1983) claim that the rift evolved as a combination of vertical (dip-slip) and horizontal (left-lateral) movement.…”

Abstract. This work presents the first palaeostress results obtained from fault-slip data along the eastern margins of the Dead Sea Rift (also named Dead Sea Transform) in South-western Jordan. Stress inversion of the fault-slip data was performed using an improved Right-Dieder method, followed by rotational optimisation. Fault-slip data (totalling 2773) include fault planes, striations and sense of movements, obtained from outcrops ranging in age from Neoproterozoic crystalline basement to Holocene sediments. The data were inverted to determine 88 different palaeostress tensors. Eight palaeostress tensor groups (stages) have been identified, ranging from the Late Neoproterozoic to the Holocene period, and have been correlated with the tectonic evolution of the Dead Sea Rift.The new palaeostress data evidence a general clockwise rotation with time of the S Hmax axis from an E-W trend in the Cretaceous to a N-S trend in the Pleistocene. Two stages can be distinguished in this rotation. The older one marks the change of the S Hmax axis from E-W to NW-SE (about 50 • rotation), and took place in the Miocene. The second one illustrates the changes of the S Hmax axis from NW-SE to NNW-SSE to N-S (38 • rotation), taking place during the Pleistocene (the last 6 Ma). The data also show the appearance of E-W extension in the Late Pleistocene, superimposed on the Dead Sea Stress Field. We therefore suggest that the Dead Sea Rift system formed in a combination of strike-slip and dip-slip movements.

“…The primary features of active plate boundaries in the vicinity of Egypt have been discussed in detail by many authors (e.g., McKenzie 1972;Neev 1975;Ben-Avraham et al 1987;WCC 1985;Meshref 1990;Kebeasy 1990). A summary of the three most important tectonic features in the vicinity of Egypt (Fig.…”

A review of seismic hazard assessment studies and hazard description in the building codes for Egypt

Reduction of damage in earthquake-prone areas requires modern building codes that should be continuously updated to reflect the improvement in our understanding of the physical effects of earthquake ground shaking on buildings and the increase in the quality and amount of seismological and tectonic studies, among other factors. This work reviews the published seismic hazard assessments available for Egypt as well as the seismic actions included in the building codes, in order to show the state-of-the-art of the seismic hazard assessment studies for the country. The review includes the history and development of seismic hazard assessments and the adoption of seismic building codes in Egypt. All the previous studies were analyzed in order to conclude that a new seismic hazard assessment according to the state-of-the-art is desirable, as well as a change in the hazard description for the actual Egyptian building code.
