We present the compilation of a new database active faults in Slovenia, aiming at introducing geological data for first time as input national seismic hazard model. The area junction Alps, Dinarides, and Pannonian Basin is moderately seismically active. About dozen M w > 5.5 earthquakes have occurred across territory last millennium, four which instrumental era. relative paucity major low to moderate fault slip rates necessitate use geologic more representative assessment hazard....

A prototype of a low-cost GNSS (Global Navigation Satellite System) monitoring system was installed on deep-seated landslide in north-western Slovenia to test its performance under field conditions. The consists newly developed stations based low-cost, dual-frequency receivers and open-source processing software. It automatically receives data transmits them over the Internet. processes server-side makes available end user via web portal. detected surface displacements were evaluated through...

Slovenia is located on an active convergent boundary between the Adriatic microplate and Eurasian plate, characterized by compressive fault systems moderate seismicity. Relatively high seismic hazard in W related to Dinaric Fault System of dextral strike slip faults. After Idrija fault, second most important more than 100 km long Raša Fault. Its activity has been estimated previous geomorphological studies rate at about 0.7 mm/year. Due its length, relatively large earthquake...

The Sava Fault, a prominent structure within the Periadriatic Fault System in Slovenian Southern Alps, plays key role deformation partitioning of Adria–Europe collision zone. However, many aspects its activity remain inadequately constrained, including slip rate and seismic history. In this study, we employed an interdisciplinary approach to investigate late Quaternary short section fault, combining high-resolution lidar photogrammetric digital elevation models, remote sensing...

Protection forests play an important role in mitigating the influence of natural hazards. Despite growing need for protective functions due to aging and increased risk disturbances, active forest management has become increasingly uncommon across Alps. Active protection can be facilitated by state subsidies. This requires objective delineation with a direct function development silvicultural techniques that mitigate A study efficiency beech-dominated Soteska gorge NW Slovenia, where main...

The economic viability of Borehole Heat Exchangers (BHEs) depends on the ability ground to exchange heat, and maps shallow geothermal potential are therefore useful planning tools for future installations. In this work, we present assessment in Cerkno, a mountain town 5,000 inhabitants western Slovenia. recently developed G.POT method was applied, taking into account site-specific thermal parameters usage profiles depending climate conditions. This work is part EU-funded project GRETA,...

This paper focuses on the studying of landslides in hinterland area Koroška Bela settlement, NW Slovenia. Research has shown that these have potential to mobilize material into a debris flow. The interest is located Karavanke mountain ridge, above settlement Bela, which lies outskirts town Jesenice. In order recognize and understand kinematics their triggering mechanisms, multidisciplinary approach using engineering-geological geotechnical investigations was applied. Thus, landslide source...

Deciphering deformation mechanisms within Quaternary sediments in a highly dynamic environment such as the southeast European Alps is often challenging task that requires use of variety methods. Due to geohazards involved, interpretation can have major impact on society and may enable preparation appropriate engineering solutions. We present an example how structures be studied by integrating geomorphological, sedimentological structural geological mapping using photogrammetric leveling...

A motorway Razdrto-Podnanos is being built across Rebrnice area in Vipava valley. There limestone scree material deposed on flysch rocks. Limestone unstable and gradually slides downslopes because of slope inclination, underground water clayey zones. Clayey zones have been created the contact between Material movements can be observed surface but they were also measured wells. composition reasons for landslides described this article.
