Summary: By using high-resolution reflection seismic imagery, this study provides insights into the formation of the Christiona-Santorini-Kolumbo (CSK) rift zone and reveals the correlation between volcanic activity and specific fault movements. The findings suggest that the tectonic evolution of the rift is controlled by deep-seated processes, and volcanic activity has a secondary feedback mechanism on the tectonic system. A comparison with neighboring volcanic fields highlights the potential arc-wide scale of the observed volcano-tectonic interplay.

Summary: The configuration of salt deposition has a fundamental influence on deformation in the south-central Pyrenees. By dividing the region into three domains, it was found that the Northern and Southern Domains have complex Mesozoic growth histories, while the Central Domain is simpler. Physical models confirmed that preexisting salt structures could generate specific patterns observed in the Southern Domain.

Summary: Detailed geological mapping and structural analysis of the western side of the Gulf of Suez has revealed two superimposed tectonic regimes: Late Cretaceous-Early Eocene transpression along deep-seated faults and Oligo-Miocene extension. The region is characterized by ENE-oriented strike-slip deformation zones, tight overturned folds, and continuous exhumation along hinge zones. Overall, the findings suggest a complex history of tectonic activity in the area.

Summary: In continental rift systems, the role of rift magmatism in topography formation, plate state-of-stress, and volcanic and tectonic processes is crucial. However, the influence of magma intrusions, crustal thinning, and rift basin and flank topography on stress field rotations in rift zones is poorly understood.

Summary: The study presents a synthesis of geological and geophysical data from the Papua-Woodlark region to characterize the present plate boundaries and derive a plate kinematic model. It provides insight into the neotectonics and past tectonics of the Australia, Woodlark, Trobriand, and Solomon Sea plates. Based on their analysis, the authors favor a plate boundary model with subduction at the Trobriand Trough, estimating current subduction rates and spreading rates along the Woodlark Basin.

Summary: Through a 60-year study of earthquake swarms in the southern Red Sea, Afar, and Gulf of Aden region, it was found that most earthquake swarms recur every few decades in the same area. The swarms are often associated with rifting events, including magmatic intrusions, surface faulting, and volcanic eruptions.

Summary: The paper presents a detailed structural mapping of the Abu Roash Cretaceous outcrop and discusses the relationship between folds and faults in the mapped area. It also highlights the unique structural deformation of the Abu Roash area compared to the northern Egypt inverted basins. The main-bounding fault of the Kattaniya basin is found to be located away from the Abu Roash outcrop.

Summary: This study focused on evaluating the risk assessment of heavy metal contamination in aquatic ecosystems in Egypt's Suez Gulf coast. The results showed that Cd and Pb are severely enriched in surface sediment from anthropogenic sources, while Al, Mn, Fe, Cr, Co, Ni, Cu, and Zn predominantly originate from natural sources.

Summary: This study assesses offshore wind power resources in selected locations in the Gulf of North Suez and recommends L1, L3, and L2 as suitable sites for wind farm development. These locations have favorable wind sources, as indicated by high wind power density, wind variability, and windy site identifier indices.

Summary: The article investigates the relationship between fault network patterns and key rift parameters in continental extension using 3D thermo-mechanical models. The study reveals key characteristics of fault patterns and highlights the importance of fault weakening and spatial distribution of initial plastic strain blocks in controlling fault characteristics.

Summary: A localized liquefaction event in the pre-rift Upper Cretaceous succession was observed at the eastern side of the Gulf of Suez rift, Egypt. The structures induced by the liquefaction include structurally controlled clastic intrusions, slump-like folds, and megabreccia. Tectonic-related seismic activity is suggested as the plausible trigger for the liquefaction.

Summary: Analyses of normal fault behavior provide insight into tectonic processes driven by plate boundary forces. The study examines normal faults in the Tamaki Makaurau-Auckland region of northern New Zealand and reveals a widespread extensional tectonic environment. The results suggest a connection between the observed fault systems in different rock formations, indicating a regional-scale extension in northern New Zealand.

Summary: This study evaluated the petrographical and petrophysical characteristics of the Rahmi sandstone gas reservoir in the southern Gulf of Suez. The study found differences in porosity and water saturation between the East Matr and Amal fields, with the Rahmi sandstone depositing in a high energy shoreface environment in close proximity to the hinterland.

Summary: This study examines the kinematics of the Appalachian decollement in the southeastern United States through the analysis of seismic receiver functions. The research reveals the presence of a subhorizontal decollement structure with dipping anisotropic foliation, suggesting a typical geometry for such structures. The findings also suggest that the Appalachian decollement accommodated westward compression prior to the late Alleghanian collision, independent of the overlying Blue Ridge-Piedmont structural inheritance.

Summary: The East Breaks foldbelt is formed by slope-parallel folds and thrusts detached on a salt canopy on the northern Gulf of Mexico slope. Structures in the foldbelt are attributed to convergent gravity gliding caused by the bend in topography in the northwest Gulf of Mexico. Convergent deformation was localized in the East Breaks foldbelt because it was a shale-dominated slope between sand-prone slope aprons during the Oligocene.
