Summary: The fault rock architecture of the Alhama de Murcia Fault (AMF) in SE Spain differs significantly from classical models, showing larger symmetry and heterogeneity within the shear zone, ranging from a stable fault core to intensely deformed damage zone, recording multiple seismic events.

Summary: The highest structural level of the Naxos metamorphic core complex, the Zas Unit, records blueschist-facies metamorphism at ca. 50 Ma during subduction, followed by crustal thickening and Barrovian metamorphism reaching peak conditions at ca. 20-15 Ma. It is suggested that the Barrovian metamorphism resulted from a 30-35 million year period of crustal thickening prior to extension, while extension led to exhumation and cooling of the crust.

Summary: Understanding the development of syn-rift carbonate systems is complex, and their facies distributions can sometimes be difficult to predict due to key factors such as tectonics, eustasy, palaeogeography and climate. The study in SE Dahra Platform demonstrates that synsedimentary faults control reservoir architecture and predict heterogeneous distributions of carbonate facies, with local tectonic deformations and sea-level changes being primary controls on platform geometry and facies distributions.

Summary: The study shows that the core of intraplate faults is wider while plate boundary faults are narrower, regardless of total displacement. Plate boundary fault earthquakes typically have a greater seismic moment compared to intraplate events with the same value of displacement. Narrow plate boundary faults dissipate less energy during earthquakes, leading to higher magnitude earthquakes due to more energy being radiated to the surface.

Summary: The study reveals that the Anghiari fault has experienced seven paleo-earthquakes in the past, with a slip rate of over 0.2 mm/yr averaged over the last 25,000 years and a recurrence interval of about 2,500-3,200 years. Furthermore, paleoseismological analysis indicates the presence of an extensional stress field throughout the sedimentation of the faulted strata.

Summary: The initiation of continental rifting in the Late Triassic was reconstructed based on the study of sedimentary formations deposited in the western end of Neotethys. The research found evidence of accelerated subsidence and changes in sedimentary patterns, indicating the onset of continental rifting. This study provides important insights into the development of crustal movement.

Summary: This study uses convolutional neural networks and Hidden Markov Models to successfully generate facies maps with a resolution of 5 meters and distinguish relative sea level fall from random variability with about 90% accuracy. The research demonstrates characteristic patterns of different sea level forcings, providing a new tool for quantitatively reconstructing ancient sea level conditions.

Summary: Oceanic transform faults, which were previously believed to be conservative two-dimensional strike-slip boundaries, are revealed to be more complex due to deeper seafloor along the faults than their associated fracture zones. Accretion at intersections between oceanic ridges and transform faults is asymmetric, with outside corners showing shallower relief and more extensive magmatism. This leads to a two-stage process of accretion at transform-fault systems, different from other regions along mid-ocean ridges.

Summary: In this study, the local tsunami hazard caused by seismic sources is evaluated using a stochastic framework. Assumptions such as static passive generation, constant rake angle, and source centroid are relaxed, and spatial uncertainties are modeled in a large set of scenarios. The proposed methodology is easy to implement and can be combined with other sources or hazards. Application in the Kuril-Kamchatkah trench demonstrates its simplicity and ability to produce hazard maps that can be replicated worldwide.

Summary: This study reveals the 3-D structure of the Kaiping Metamorphic Core Complex (KP MCC) and its associated detachment fault using high-resolution 3-D seismic reflection data. The KP MCC is characterized by the ascend of ductile midcrustal materials and the partially exhumed KP9 High. The KP detachment fault displays a domed low-angle geometry with pronounced NS-plunging corrugations. The data also provide evidence for the kinematic process of the rolling-hinge activity and suggest that the presence of a pre-existing midcrustal ductile layer and basement structures within the upper brittle crust favored the development of the KP MCC in the northern South China Sea margin.

Summary: This article proposes the development of an air core current limiting reactor with a controller for AC fault current limitation in low and medium voltages. The reactor consists of an air core transformer, with its primary winding connected in series with the radial network AC system, and its secondary winding fed from a voltage transformer stepped down from the network voltage. The performance of the reactor is investigated under various parameters and fault conditions, and its advantages over other current limiters are discussed.

Summary: The Bandar Jissah Basin in southeast of Muscat, Oman, exhibits a transition from supradetachment to rift basin setting, with sediment sourced from the Semail Ophiolite and Saih Hatat window. The sedimentary facies belts in the basin include alluvial fan conglomerates, braidplain, mouth bar, shoreface and carbonate ramp deposits.

Summary: This study focuses on a high-resolution stratigraphic, sedimentologic, petrographic, and limnogeological investigation of the Agua de la Zorra depositional system to understand its evolution through space and time and to reconstruct the development of the carbonate factory within the palaeolake. The results strongly support volcanism and tectonics as the main allogenic factors controlling the Agua de La Zorra lacustrine system evolution.
