• Reliable probabilistic landslide susceptibility mapping using a calibrated stacked ensemble with bootstrap-based uncertainty

  A groundbreaking landslide susceptibility mapping (LSM) framework achieves unprecedented accuracy and reliability for mountainous regions, setting a new benchmark with an AUC of 0.979 and Brier score of 0.054 in the geomorphically complex Upper Svaneti region of northern Georgia. This study introduces a robust machine learning workflow that integrates CatBoost, Random Forest, Extra Trees, and a multilayer perceptron within an XGBoost meta-learner, optimized via spatial cross-validation to handle class imbalance effectively. Unlike conventional approaches, this method combines exploratory geomorphic structure analysis with probabilistic uncertainty quantification using bootstrap ensembles and isotonic calibration, ensuring statistically robust and probabilistically interpretable susceptibility maps. The systematic increase in susceptibility with slope angle further validates the model's geomorphic consistency, offering a reproducible solution for risk-informed planning in tectonically active landscapes.

• The Panel of the Virgin and Saint Anne from the Church of the Archangels in Iprari. Iconographic and Ideological Aspects

  A rare eleventh-century iconographic panel depicting the Virgin and Child with Saint Anne, discovered in the Church of the Archangels in Iprari (Upper Svaneti, Georgia), reveals significant political symbolism. This panel, part of the earliest works attributed to 'King’s Painter Tevdore,' stands out within a limited decorative program of a small church dedicated to archangels. The study argues that its inclusion suggests a deliberate ideological and political message, linking royal patronage with religious imagery during the period between 1096 and 1130. The research combines topological analysis, iconographic context, and historical inscription evidence to uncover this layered meaning.

• Main Geographical Factors of Settlement Patterns and Natural Resource Use in Mountain Region: The Kvemo (Lower) Svaneti (Lentekhi Municipality) Case

  In Kvemo (Lower) Svaneti, geographical conditions and natural resource use significantly shape settlement patterns and agricultural practices. The study identified 15 distinct landscape units using GIS technology, revealing that 43% of the region lies above 1000 meters in elevation. Livestock farming dominates agriculture, with pastures and haylands covering 92.4% of agricultural land, while crop farming is limited to areas below 900 meters. The research also highlights a trend of increasing abandoned villages, with 83% of the population residing in small settlements of up to 200 dwellers. Traditional practices play a crucial role in sustaining livestock farming, contributing to the region's unique cultural and economic landscape.

• Analysing debris flow impact in Upper Svaneti, Georgia: investigating triggering factors and runout dynamics

  A critical rainfall threshold of over 7 days has been identified as sufficient to trigger debris flow failures in the deposition zones of Upper Svaneti, Georgia. This finding, derived from a combination of numerical modeling and high-resolution UAV data analysis, highlights the region's vulnerability to increasing extreme weather events. The study employed TRIGRS and RAMMS models to simulate slope instability and runout dynamics, respectively, using laboratory-tested soil samples and historical rainfall records for validation. While the models accurately predicted detachment zones in a 2022 event, deposit heights were slightly underestimated, suggesting potential underestimation of hazard risks under moderate rainfall conditions if residual materials are remobilized. These insights provide actionable data for hazard mitigation strategies, early warning systems, and regional planning to address growing concerns in mountainous regions.

• Cyclic and Monotonic Behaviour of Coarse Mixed Soils from Debris Flow Slopes: Large-Scale Triaxial Insights

  Loose, mixed-grain soils—common in debris flow-prone slopes like those in Upper Svaneti—are far more vulnerable to liquefaction and cyclic degradation than previously understood. Large-scale triaxial tests reveal that such soils can lose up to 90% of their stiffness and exhibit extreme damping (over 100%) when subjected to moderate cyclic stress ratios (CSR ≤ 0.4), particularly if they start with a void ratio ≥ 0.85. Denser soils, however, remain stable until CSR exceeds 1.0. The study also shows that load reversal patterns and initial stress conditions significantly accelerate pore pressure buildup, increasing the risk of slope failure. These findings provide critical data for hazard prediction in dynamic geological environments.

• Toponymic Searches on the Border of Svaneti and Abkhazia

  A new understanding of the historical border dynamics between Svaneti and Abkhazia emerges from a detailed analysis of toponymic sources, revealing shifts in territorial boundaries over centuries. The study, which examines church documents, lectionary sheets, and ethnographic data, identifies previously unrecognized patterns in border toponymy and land ownership, particularly in Upper Svaneti's northwest region. By applying critical source analysis and historical-comparative methods, researchers have reconstructed the fluid nature of these borders, highlighting how written monuments, toponyms, and ethnographic evidence collectively illustrate their evolution. The work also underscores the need for further ground-based studies to refine boundary clarifications in contested regions like Dali Valley.

• Ethnolinguistics of the Dali (resp. Kodori) Gorge

  The Kodori Gorge, a historically significant region in West Georgia, exhibits a rich linguistic and toponymic diversity shaped by millennia of cultural exchange. The study reveals that the gorge's toponymy reflects multiple layers of historical influence, including Svan, Abkhazian, Megrelian, and Russian elements, with Svan origins dominating microtoponyms, hydronyms, and oikonyms. Notably, the Kodorian Svan dialect demonstrates interferential linguistic features, blending Upper and Lower Bal dialects at phonetic, morphological, and syntactic levels. This interference suggests a distinct dialectal identity for Kodori's speech, supported by decades of systematic onomastic and ethnolinguistic fieldwork. The research underscores the strategic importance of the gorge as a crossroads between Byzantine and Central Asia, with its toponymy serving as a 'language of earth' that encodes historical movements and cultural interactions.
