Summary: The newly developed method of optically stimulated luminescence (OSL)-depth profiles (DPs) provides a novel way to reconstruct and quantify fault slip. By studying a targeted bedrock fault scarp in north China, the method was found to produce age calculations consistent with paleoseismic trenching studies, and potentially identify previously unidentified seismic events.

Summary: Paleoearthquake studies rely on untested assumptions of sediment transport. A new test using luminescence as a tracer reveals complex sediment transport processes beyond existing models, which may lead to preservation bias in paleoearthquake records. Attention to site-specific mechanics is necessary to mitigate the effects of preservation bias in paleoseismic studies.

Summary: Lifelines, such as pipelines, roads, and tunnels, must consider the fault displacement hazard when crossing active tectonic faults. Probabilistic fault displacement hazard analysis (PFDHA) provides a suitable tool for assessing this hazard. A simplified approach for engineering applications is presented, focusing on lifeline-fault crossing and allowing for broader applicability. Investigation of key parameters and their impact on hazard level is included. This approach will be used to approximate fault displacement in Eurocodes.

Summary: The Featured Application Methodology developed for the Paks nuclear site in Hungary aims to contribute to safety justification. State-of-the-art hazard analysis methods provide fault displacement hazard curves, but evaluating ground displacement hazard requires significant effort and data. The proposed methodology, based on seismotectonic modeling and probabilistic seismic hazard analysis, offers a conservative assessment of fault displacement probability to determine its relevance to nuclear power plant safety.

Summary: This study conducted two-dimensional nonlinear finite element analyses to investigate seismic deformation patterns of soil slopes. The results showed that deeper sliding masses experience notable strain localization at the sliding mass depth, while shallow sliding masses experience more distributed straining throughout the entire soil mass. The numerical simulations also revealed that factors such as shear wave velocity, slope height, and slope angle significantly affect the resulting displacements of the slopes.

Summary: This study estimated the slope-length and slope-steepness (LS) factor for the entire watersheds of Afghanistan using three different methods. The results showed that Methods 1 and 2 were more appropriate than Method 3. The northeast, north, and central regions of Afghanistan were found to have the highest LS values, indicating a high vulnerability to soil erosion by rainfall-runoff processes. The average annual soil loss in the Upper-Helmand River Basin was estimated to be 9.3, 18.2, and 11.1 (ton/ha/year) by using the three methods, with corresponding SDR of 23.5%, 12.1%, and 19.9%.

Summary: The Sencelles Fault, with a NE-SE orientation, is the main extensional structure of Mallorca Island in Spain and is believed to be the possible source of the 1851 CE Palma earthquake. Through lichenometric analysis and measurement of Aspicilia calcarea (Ac) and Aspicilia radiosa (Ar) specimens on tombstones and funerary monuments in nearby cemeteries, the local lichen growth rates (LGR) were determined. The analysis suggests that the studied segment of the fault is not a co-seismic surface faulting related to the 1851 CE event, but a secondary earthquake effect on a pre-existing fault scarp.

Summary: This paper suggests a performance-based method to assess permanent displacement of a slope, considering uncertainties in ground motions and basic soil parameters. The method includes analyzing statistics of permanent displacement at different peak ground acceleration levels and deriving fragility curve through regression analysis. The study shows that soil property uncertainties can contribute up to 40% to the uncertainty in permanent displacement.

Summary: Short circuits pose a major concern in power distribution systems as they can disrupt energy supply and impact the quality of power delivered to consumers. Fault location in radial distribution networks, complicated by lateral branches, leads to multiple estimations. This study focuses on addressing the issue of multiple estimations in fault location, specifically with the use of impedance-based fault locators, and demonstrates a successful approach in minimizing errors and optimizing the trade-off between investment and reduction of estimation regions.

Summary: The Kaikoura Earthquake uplifted Kaikoura Peninsula by approximately 1 m, mainly resulting from slip on multiple faults. The variable co-seismic uplift in 2016 can be reproduced by slip on different faults. The tilting of Late Quaternary marine terraces is primarily influenced by slip rates on the OSTF and ABF.

Summary: Small depressions in the north-eastern part of October Revolution Island are filled with continental terrigenous rocks from the Upper Carboniferous-Lower Permian period. The U-Pb dating of these rocks suggests that they are mainly derived from the Ordovician period, with a smaller contribution from the Silurian period. The combined U-Pb and (U-Th)/He ages indicate a Late Carboniferous uplift of approximately 6-7 km in the provenance area. The presence of Ordovician magmatic and volcanic rocks in the north-eastern October Revolution Island suggests that Late Paleozoic tectonism significantly affected the southern margin of the Kara terrane and its north-eastern part.

Summary: New U-Pb and double dating (U-Pb and U-Th)/He) age determinations on detrital zircons from Upper Cretaceous-Miocene formations greatly improve our understanding of evolutionary and clastic provenance models in southern Mexico and the western Caribbean. The data suggest a south-to-north transport of clastic detritus into the Chiapas Foldbelt Basin and the Sureste Basin, supported by palinspastic reconstructions and fission track data. Zircon data on volcanic breccias from the Salina Cruz wells imply a displacement of the Guerrero Arc. This data supports Pacific-origin Caribbean models and identifies arc collision and orogenic highlands in the Maastrichtian and Paleogene periods.

Summary: The study presents the first ages of pre-impact magmatic dikes preserved in Chicxulub's peak ring, providing insights into the subsurface composition and evolutionary history of the Yucatan Peninsula. The dating results reveal two age groups, Carboniferous dacites (328-318 Ma) and Jurassic dolerites (169-159 Ma), suggesting the presence of previously unsampled magmatic phases. The investigation of isotopic compositions further indicates that the dolerites contributed significantly to the Chicxulub impact melt rock, representing a pervasive Jurassic magmatic phase associated with the opening of the Gulf of Mexico.

Summary: A greater amount of halogens is subducted globally compared to what is erupted at magmatic arcs, suggesting an increase in the mantle halogen budget or an additional output pathway. The sub-continental lithospheric mantle (SCLM) can act as a reservoir for volatile elements through metasomatism. This study analyzes the halogen content of xenoliths from various locations to understand the effects of subducting plate metasomatism on the western North American SCLM. The results indicate that the Farallon plate sequestered halogens in the SCLM of the central and south Colorado Plateau and the southern Rio Grande Rift.

Summary: We present new zircon (U-Th)/He ages and detrital zircon U-Pb ages from psammitic greyschists in the Otago Schist, New Zealand, revealing the activity of low-angle faults and the complex terrane and metamorphic history of the region. The samples indicate extensional tectonics and a late Early Cretaceous ductile extensional lower plate within a metamorphic core complex. The detrital zircon ages suggest Carboniferous, Permo-Triassic, Jurassic, and Cretaceous maximum depositional ages for the schist protoliths.
