Summary: This study proposes a high-precision measurement method for conventional crop height measurements using aerial drone images. The method utilizes a drone equipped with a monocular camera and real-time kinematic global navigation satellite system (RTK-GNSS) for real-time processing, and performs high-precision stereo matching based on long-baseline lengths. A new calibration method is also proposed to improve accuracy and speed. The method demonstrated a significant reduction in error rates compared to conventional methods in natural world environments.

Summary: This study demonstrates the utilization of high-resolution point clouds from lidar and UAV photogrammetry for the investigation of large-scale slope instabilities in Switzerland. By analyzing the point cloud data, differences in kinematic behavior of individual rock compartments, active shear planes within the moving rock mass, and the kinematic process driving the slope displacements were identified. Furthermore, basal sliding planes were modeled based on the 3D surface movements of rock slides, displacement angles were calculated accurately, and estimates on destabilized rock volumes were provided. This information significantly contributed to the understanding of the processes and supported decision-making in hazard management.

Summary: Landslides can cause significant damage to landscapes, infrastructure, and human lives globally. The Himalayas are particularly vulnerable to landslide hazards due to their active tectonics and diverse climatic conditions. The Danna-Sahotar Landslide in Muzaffarabad, Pakistan, serves as an example of the devastating impact of landslides on infrastructure and settlements. By utilizing unmanned aerial vehicle photogrammetry and electrical resistivity tomography techniques, a comprehensive understanding of the landslide was achieved, highlighting its multiple failure mechanisms and the role of hydrogeology in reducing stability.

Summary: This study analysed the land movement in Battersea, London, and found an average land subsidence rate of -6.8±1.6 mm/year, which was attributed to large groundwater withdrawals and underground pile construction for the renovation work. It underscores the critical interdependence between civil engineering construction, groundwater management, and land subsidence, and emphasizes the need for holistic planning and sustainable development practices to mitigate the adverse effects of construction on groundwater resources and land stability.

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: This study presents a new methodology for analyzing the geometrical behavior of burial structures in southern Egypt. The researchers used photogrammetric and laser scanning surveys to obtain accurate 3D models, enabling a complete geometrical analysis. The results suggest that the ancient Egyptians had a proportional canon for planning and constructing these hypogea, which was confirmed by a large amount of data extracted from the 3D models.

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: A dedicated procedure has been implemented to explore the behavior and define the state of activity of 279 deep-seated gravitational slope deformations (DsGSDs) in the Aosta Valley Region. The procedure involves the use of Differential Interferometry Synthetic Aperture Radar (DInSAR) techniques to detect and identify Persistent Scatterers (PSs) and assess Sentinel-1 data coverage. Spatial analysis based on cluster and outlier identification is carried out to characterize the moving phenomena and their degree of variability in deformation rates. The methodology provides a valid instrument to remotely define the state of activity of these phenomena, which are often underestimated or neglected in risk management.

Summary: The widespread availability of Sentinel-2 data and high-resolution images makes it possible to map shallow landslides triggered by extreme events at a low cost. This study presents a two-phase procedure to detect and map shallow landslides using Sentinel-2 images. The results show that the semi-automatic mapping based on Sentinel-2 allows for detecting the majority of shallow landslides larger than satellite ground pixel.
