The paper explores and documents the Eocene limestones from the Albeşti village (Argeş County, Romania) in terms of the relationship between geology, geoheritage and cultural heritage. Known as the Albeşti Limestone/Stone, this rock, extracted from small quarries, has been used for centuries in the construction of an impressive number of public bui...

The paper presents a methodology to rapidly assess and map the landslide kinematics in areas with dense vegetation cover. The method uses aerial imagery collected with UAVs (Unmanned Aerial Vehicles) and their derived products obtained from the structure from motion technique. The landslide analysed in the current paper occurred in the spring of 20...

It is well known that geological structure is one of the main predisposing factors that control landslide occurrence at regional scale. Along time, investigation of the role of structural and lithologic controls has raised the interest of specialists from various earth and planetary sciences who proposed different approaches that range from descrip...

Debris flows and debris floods are rapid mass movements that occur in rugged mountain areas. The differences between them consist in the quantity of water input, which in turn influences the type of flow. For practical reasons, these two process types should be differentiated because different remedial measures should be applied for planning purpos...

With the increasing availability of data with very high and ultra-high spatial resolutions, the need to automate processes for mapping natural hazards has also increased. More and more applications are using deep learning algorithms to extract, track and classify valuable information from aerial images, satellite images or aerial geocoded videos. O...

Performing landslide hazard assessments requires modelling both the spatial and the temporal dimensions of landslide occurrences. However, most landslide hazard predictions only refer to terrain's susceptibility without including information on the temporal component of the hazard. Weather forecast platforms provide, in a very simple manner, inform...

Romania represents one of Europe’s most active landslide hotspots. The importance of studying these phenomena is both fundamental (establishing the morphogenetic and morphodynamic frameworks) and applied (quantifying and predicting the potential losses inflicted by such processes). The analysis of agents–processes–forms can be directed toward predi...

Debris flows (DF) are one of the dominant geomorphic processes and play an important role in the present-day morphodynamics of the steep slopes and stream channels in the Romanian Carpathians. A large number of studies describe the characteristics, dynamics, and site occurrence of various types of active present-day mass movement processes affectin...

The relationship between bedding planes and topographic slopes plays a major role in controlling landslide mechanisms. The catastrophic nature of many landslides around the Globe was proved to have a relevant structural background. This paper aims at analyzing the relationship between the spatial distribution of landslides and geological structure...

Most of the present day studies make use the 2.5D raster data formats for the landslide susceptibility analysis at regional scales. This data format has some disadvantages when geological and lithological settings are spatial dis-cretized, hence these disadvantages propagate in the landslides susceptibility analysis and especially where only surfac...

This paper focuses on characteristics of debris flows from the lower part of the Lotru River basin (South Carpathians, Romania). The damage produced by these debris flows has included burial of agricultural land, roads covered by debris flows, and even the obstruction of the Lotru River. Simple statistical analysis has been used to emphasize the ch...

Limestone cliffs, called "canarale" on the right bank of the Danube River, in the region Hârșova - Topalu - Capidava, are an important site of geological and paleontological intereset. These rocks hide a treasure of rare scientific value, i.e. creatures that inhabited a reef (spoges and corals) in the Upper Jurassic period (150 million years ago),...

The Red Lake is one of the few great natural lakes formed by a landslide in Romania with a surface of 30 ha. Today, specialists have two theories about the triggering mechanism. The first one accepts that the landslide was triggered in 1837 during a heavy rainfall period. The second one refers to the earthquake from January 11 (January 23 in new ca...

Rockfalls - a natural hazard – can occur isolated in our country but they produce serious damage, hurting and even killing peoples. Despite all financial losses, rockfalls were not studied in Romania by the geomorphologists and engineering geologists. Those events are strictly linked with those climatic one and also with human activities which crea...
