Summary: Research on the Bengal Basin primarily focuses on its geologic evolution and anthropogenic effects, but there is limited research on the geomorphic response to tectonic activity. This study investigates the river response to ongoing tectonics in the Chittagong Tripura Fold Belt and Indo-Burman Range by analyzing channel geomorphic metrics and river profile forms. The results show that the major rivers and their tributaries are in a transient state related to the region's ongoing tectonics.

Summary: Increasing knowledge in computer algorithms for calculating morphometric properties of the Earth's surface has led to the development of many semi-automated methods for extracting and classifying landforms. The use of digital elevation models (DEMs) and specific algorithms in GIS applications has made it easier and faster to recognize landform classes. This paper presents a new toolbox based on Jenness's landform classification, with revisions to the standard landform classes extracted by GIS. The toolbox allows for the extraction of 48 landform classes and refines the classification of landform features in different natural landscapes.

Summary: This study evaluated the relative tectonic activity of the Northern Sumatran Fault using geomorphic indices. The results showed alternating moderate and high tectonic activities along the fault, with a decrease in activity towards the north. The distribution of seismicity coincided with the variation in relative tectonic activity, suggesting long-term tectonic deformation of the fault.

Summary: This study used mathematical morphology and remote sensing images to interpret the evolutionary process of loess tablelands, loess ridges, and loess hills in the Heshui County watershed. By analyzing the geomorphic characteristics and parameters, the study established classification criteria and quantified the evolutionary pattern of LT-LR-LH landforms. The findings provide new insights into the evolution of loess landforms and the disappearance of loess tablelands.

Summary: The study of Earth surface processes has evolved from descriptive to quantitative science, with increasing importance of geomorphic forecasts due to technological advancements and climate change. Developing socially relevant forecasts of Earth surface change, known as earthcasting, involves generating clear, testable predictions with quantitative uncertainties and engaging stakeholders and the public to evaluate socioeconomic impacts. Earthcasts bridge the gap between researchers and decision-makers, emphasizing the social benefit of geomorphology research.

Summary: Geomorphological analysis was conducted to investigate the tectonic fault in North Central Vietnam, revealing moderate to weak modern activity of most faults with only a few segments showing strong activity. Displacement and slip data analysis helped identify the strike-slip tectonic stress state of Pliocene-Quaternary period in this area, providing new insights into the contemporary crustal stress orientation of North Central Vietnam and potential seismic hazards assessment.

Summary: This study designed a workflow to investigate potential areas of neotectonic deformation using well-developed techniques, despite the site having low relief and low to moderate tectonic activity. The results showed that the combination of cluster analysis, detailed morphometric analysis, and mapping known structural features could efficiently identify neotectonic activity in such areas. Additionally, the research extended the application of morphometric analysis to regions with low relief and tectonic activity levels.

Summary: Lowering flood embankments on the River Dee in Scotland improved hydrogeomorphic connectivity between the river channel and floodplain, resulting in channel aggradation, bank erosion, and gravel deposition. Monitoring showed that this targeted action increased floodplain water levels and decreased the threshold river discharge for backwater connection, enhancing future catchment resilience. Such interventions may benefit water storage and biogeochemical processing in the long term.

Summary: This article addresses the issue of interpreting geochronologic data in the Betic-Rif orogen. Through 40Ar/39Ar dating of white mica samples, it reveals a HP event in the Early Eocene (around 38 million years ago) and a regional stage of exhumation at 20 million years ago. This study provides compelling evidence for overcoming the problem of extensive late-orogenic overprinting.

Summary: The study focuses on the post-metamorphic folding and faulting of the central unit at the boundary between Ossa-Morena and Central Iberian Zone, suggesting that the rocks in the central unit do not exhibit a flat-lying attitude but a NE-dipping tectonic/lithological layering. The kinematics of the highly-dipping Azuaga Fault, which limits to the SW the central unit, does not contribute to uplift the Central Unit rocks during the late Variscan evolution.

Summary: A single plate boundary fault system in the western Mediterranean, which represents an underappreciated seismic and tsunami hazard, has been identified. The current diffuse-strain model of plate collision in the region is untested due to most deformation occurring underwater. By analyzing active offshore fault systems, the slip of the fault system and its hazard level have been estimated.

Summary: The Ossa-Morena Zone is a Gondwana-related terrane composed mainly of Cambrian rocks. U-Pb dating of zircon grains from 15 samples revealed the absence of a significant Stenian-early Tonian population in the Cambrian Ossa-Morena rocks, in contrast to the results from middle Ordovician-Lower Devonian rocks in the same area. This suggests a change in the paleogeographic/paleotectonic evolution of the Ossa-Morena Zone during the late Ediacaran-early Ordovician period, possibly involving an eastward displacement and a reorganization of drainage systems.

Summary: This study improves landslide mapping by integrating data from Differential Synthetic Aperture Radar (DInSAR) and Landscape Analysis using the normalised channel steepness index (k(sn)). The case study area is the southwestern sector of the Sierra Nevada mountain range in Southern Spain. By proposing the double normalised steepness (k(snn)) index, the active tectonics signal is removed, and the DInSAR analysis highlights the slopes of interest. This study provides a new inventory of 28 landslides, revealing a higher landslide area compared to previous mapping methods.

Summary: Coastal regions in Southwest Europe have undergone significant changes due to tourism-related urban development, making them highly vulnerable to the impacts of climate change. This study analyzed extreme weather events along the Atlantic and Mediterranean coasts of Southwest Europe from 2009 to 2020, quantifying their impacts on fatalities, injuries, and economic losses. The results showed an upward trend in the number of events, as well as human losses and damages. The Mediterranean coast, especially the Spanish Mediterranean coast, had a higher exposure due to rapid tourism growth and inadequate preparation for marine storms.

Summary: This study presents and discusses the stress-strain behavior of overconsolidated clay samples from Campo de Gibraltar Flysch Through Domain in South Spain. The samples were identified and classified following ASTM standards, and their chemical and mineralogical composition were determined using chemical and X-ray techniques. The samples were tested under triaxial and oedometric conditions, and a comparison was made between different constitutive models and real testing data using the finite-elements method. The results indicate that the Hardening Soil constitutive model provides a better fit than the Modified Cam-Clay model, especially for lower strain values (<5%). These findings are important for the design of the Strait of Gibraltar tunnel project.

Summary: Landslide occurrence in Colombia is frequent due to its geographical location, with steep and complex terrain. The study area around the Bogota-Villavicencio road is one of the regions with the highest concentration of landslides. A detailed analysis of 2506 landslides reveals five basic typologies and landslide susceptibility models have been made using different methods and input factors. The results show that machine learning methods, especially random forest, are the most suitable, with high accuracy and success rates. An integrated landslide susceptibility map has been created based on geological control.
