On February 6, 2023, devastating earthquakes occurred in southeastern Turkey related to the East Anatolian Fault Zone (EAFZ) and the Dead Sea Fault Zone (DSFZ). Two destructive earthquakes with moment magnitudes (Mw) of 7.8 and 7.6, especially in Kahramanmaraş, followed by an Mw 6.4 earthquake in Hatay, and many small to medium-sized aftershocks afterward, significantly impacted 11 provinces of Turkey, causing extensive damage, loss of life, and property. From the first day, numerous studies have been conducted by various disciplines on the dynamics, effects, and reflections of the earthquakes in the field.
The focus of the research is on the relationship between the effects of the earthquakes and the morphological units and their geomorphological conditions. First and foremost, the fact that these earthquakes were felt
over a vast geographic area and caused destruction and significant loss of life and property even in provinces far from the focal point demonstrates the complexity and importance of the event. This situation
necessitated the examination of many and varied geomorphological units over a wide area. It is evident that these earthquakes did not exhibit the behavior of previously known earthquakes. On the other hand, it is
clear that destructions occurred regardless of the proximity to or distance from the main fault lines.
Therefore, the subject that needs to be emphasized and investigated in recent earthquakes is not only the regional tectonic source processes related to plate interactions and the dynamics that produce earthquakes
but also geomorphological conditions, particularly the connections and relationships of morphological units with each other. In this context, due to the effects of basins and plains, it is crucial to explain the formation
mechanisms, geometries, and ground amplification behaviors of these morphological units.
In this study, the spatial distribution of the initial effects of the destructive earthquakes that occurred on February 6 and afterward was mapped, the most affected areas were associated with geomorphological
structures emphasizing the basin effect, and the importance of geomorphological factors alongside tectonic lines was highlighted. The most important finding of the study is the revelation of the need for an approach that takes into account geomorphological factors among others to help reduce the potential damage of earthquakes, understand their effects better, and predict them.

Water erosion is an important erosion type that erodes and transports the most. With the effects of stream water, both streambank and gully erosions cause even more soil transport and debris accumulation resulting more flood events and associated loss of life and properties, as well as increasing the deposition of sediment in dam reservoirs that shorten the economic lifespan of these dams. This study was carried out in 14 different bank erosion sites (stream reach) in the Oltu Micro Catchment (OMC), one of the sub-watershed of the Coruh River Basin, to measure gully and streambank erosions over five-year long study period using “erosion pin method”. Oltu Micro Catchment has arid and semi-arid climate and has a 37% slope degree with a rugged structure. Over the five-year study period, the annual gully and streambank erosion rates were ranged from 1.25 to 8.79 cm/yr and the five-year average was measured as 4.43 cm/yr. The five-year soil losses were ranged from 30.5 to 190.8 tons/km/y...

Dinàmica dels ecosistemes mediterranis i la seva estreta relació amb els incendis forestals i també amb els grans incendis forestals.
Els incendis forestals han coevolucionat amb el paisatge vegetal mediterrani des de fa segles. La conca mediterrània, i sobretot l'occidental, han estat testimonis i elements indicadors d'aquesta coevolució. Cal esmentar tot el llevant dels Països Valencians i la totalitat de la terra baixa de Catalunya.
El massís de Garraf ha estat l'ecosistema menys poblat de Catalunya els últims segles, malgrat la proximitat i l'equidistància de dos grans urbes costaneres: Barcelona i Tarragona. Per això és un bon element indicador d'aquesta coevolució foc forestal - modelat de la vegetació.
El Prof. Dr. Josep Antoni Herrera Sancho ha estudiat amb molt detall, i des de l'any 1974 i fins a l'actualitat, aquesta coevolució en el massís de Garraf, ja que es troba colindant al el seu lloc de residència.

Karst caves are unique biogeomorphological systems. Cave walls offer habitat for microorganisms which in-turn have a geomorphological role via their involvement in rock weathering, erosion and mineralisation. The attenuation of light with distance into caves is known to affect ecology, but the implications of this for biogeomorphological processes and forms have seldom been examined. Here we describe a semi-quantitative microscopy study comparing the extent, structure, and thickness of biocover and depth of endolithic penetration for the Puerto Princesa Underground River system in Palawan, the Philippines, which is a natural UNESCO World Heritage Site. Organic growth at the entrance of the cave was abundant (100% occurrence) and complex, dominated by phototrophic organisms (green microalgae, diatoms, cyanobacteria, mosses, and lichens). Thickness of this layer was 0.28 ± 0.18 mm with active endolith penetration into the limestone (mean depth = 0.13 ± 0.03 mm). In contrast, phototrophs were rare 50 m into the cave and biofilm cover was significantly thinner (0.01 ± 0.01 mm, p < 0.000) and spatially patchy (33% occurrence). Endolithic penetration here was also shallower (< 0.01 mm, p < 0.000) and non-uniform. Biofilm was found 250 m into the cave, but with a complete absence of phototrophs and no evidence of endolithic bioerosion. We attribute these findings to light-induced stress gradients, showing that the influence of light on phototroph abundance has knock-on consequences for the development of limestone morphological features. In marine caves this includes notches, which were most well-developed at the sheltered cave entrance of our study site, and for which variability in formation rates between locations are currently poorly understood.

The Lancaster Cave and Mine Research Society was responsible for archaeological investigations at a number of cave sites across Cumbria and North-West Lancashire. It also undertook industrial archaeological investigative work on both surface and underground sites focussing on the area around Warton Crag. During the thirteen years of the society's existence it recorded this work in a number of society publications as well as more widely in the regional and national caving science press. On the cessation of the society activities much material was dispersed and lost but the work they undertook and published is still pivotal to our understanding of the archaeology, speleology and mining history of the region.

L'especial constitució i dinàmica del paisatge vegetal mediterrani, sota un clima alhora característic i particular, comporta la relativa presència del foc forestal com a element dramatitzador i regulador de l'ecosistema. Tant és així que resultaria incomprensible l'existència d'un sense l'esporàdic flagell de l'altre.
La incidència humana a l'àrea mediterrània esdevé proverbial des de temps remots. Algunes de les grans civilitzacions van discórrer al seu si. L'últim segle XX, però, l'habitual bonança climatològica i l'atractiu de les seves costes han comportat un important moviment migratori i colonitzador que, afegit als grans desplaçaments de masses del turisme, sotmeten el fràgil i malmès ecosistema mediterrani a una pressió insuportable. L'increment en la freqüència i extensió dels incendis forestals és un bon element indicador i, alhora, la conseqüència traumàtica d'una inadequada política de gestió forestal.
La desaparició secular de les originàries comunitats vegetals clímax, la degradació i simplificació de l'ecosistema, la invasió de coníferes oportunistes que homogeneïtzen la cobertura forestal i incrementen el risc i la velocitat de propagació dels incendis, entre d'altres, són un bon exemple.
Quina és la situació al massís de Garraf pel que fa a la seva difícil però possible recuperació ecològica, i quina hauria d'èsser l'actuació sobre el paisatge vegetal, al marge de l'espectacularitat i l'oportunisme político-administratiu de certes mesures actuals, són les preguntes a què mira de respondre aquesta prospecció de camp al massís, dirigida i explicada en detall pel Prof. Dr. Josep Antoni Herrera Sancho, Cap de la Secció de Botànica de l'IEP, i profund coneixedor del massís de Garraf des del 1970.

In the scope of this study the detection of the structural-geologic pattern in Central Egypt was carried out based on different open-source satellite data (Landsat, ASTER, Sentinel 2, Sentinel 1 and ALOS PALSAR radar data), as well as on Orbview3, Google Earth and Bing Map high resolution satellite images. Some of the structural and lithologic features seem to trace rifting and gliding processes, especially along the N-S oriented Kharga valley and at the western and southwestern margin of the Sinn el Kaddab plateau. Circular and oval-shaped structures, obviously related to rotation, and block-wise movements of dislocated blocks could be observed on the different satellite images. Morphometric maps and indicators derived from Digital Elevation Model (DEM) data supported the detection of neotectonic deformations and of mass movements along the borders of the Sinn el Kaddab plateau. Because of these traces of intense geodynamic and geomechanically strain in this area the question arises, whether these traces are related to larger rifting processes along the Kharga valley and the SW border of the Sinn el Kaddab plateau or are just the result of block-wise uplifting of the Sinn el Kaddab plateau with different intensities, including isostatic and tectonic subsidence at the margins. Based on the gained knowledge by evaluations of remote sensing data areas for further, focused research with adapted geophysical methods could be pointed out.

Chemical and physical proxy data from a precisely dated early last glacial (~113-110 ka, MIS5d) Sardinian stalagmite reveal a sub-millennial-scale, cool-dry climate event centered at 112.0 +0.52 /-0.59 ka, followed by a rapid return to warm-wet conditions at 111.76 +0.43 /-0.45 ka. Comparison with regional speleothem records and the palaeotemperature proxy record from the NGRIP ice core (Greenland) suggests that this event corresponds to Greenland Interstadial (GI) 25b and 25a, an intra-interstadial climate oscillation within GI-25, according to the recent Greenland stratigraphic framework. The speleothem age is in reasonable agreement (within 0.8 kyr) with that of the corresponding event in Greenland based on the GICC05modelext ice chronology but is older by about 3.7 kyr than the Greenland age based on the AICC2012 chronology.

Fossiliferous limestones are found in our buildings since the beginning of history. The fossils found within these limestones are made mostly of invertebrates or microfossil remains, and were the earlier fossils to be known and described later by science. Biogenic limestones abundance has made them a main carbonate source used in building construction as well as an important ingredient for mortars since 4600 years ago. Lime and softer building stones were often made using fossiliferous limestones, gluing the stones using mortars evolving with an increased amount of carbonates from Greek and Roman mortars up to 70% as in current Portland cement. A review based on the available historical information plus fieldtrips allow a comparison telling the history, classification, relevance, heritage and legal status of fossils and limestones using two main opposite examples, Egypt in the Old World, and Chile in the New World. An account with the first detailed description of Chilean coquinas done a century before their formal definition and the history of its use since the XVIII century are reported here.

En la depresión erosiva de Bardenas Reales tienen lugar varios procesos de erosión: rilling, gullying, piping, movimientos de masas, y en menor orden la formación de armored mud balls. El mayor o menor desarrollo de todos estos procesos guarda relación con las condiciones meteorológicas de la zona y con las características físico-químicas de los materiales. El principal condicionante de los mecanismos y procesos de erosión actuantes en esta área son las propiedades físico-químicas del material y la distribución de las precipitaciones a lo largo del año. Otros factores, como la pendiente, condicionan la infiltración de la escorrentía lo que inhibe el desarrollo del piping y favorece la formación de deslizamientos y coladas de barro.

The Pál-völgy Cave under the hills of Budapest got into focus recently as in 2011 it became the largest cave system of Hungary with 28.6 km length. This study is about a pioneer modeling method which was able to predict the size of the cave system from archive cave maps. The modeling was primarily aimed to determine the volume of the cave in cubic meters and in percentage of the incorporating limestone and marl, but through this it revealed that approximately 2/3 of the cave is unexplored.

We present the results of the geomorphological mapping of a region of the Dhofar (Sultanate of Oman) including two contrasting physiographic units sharing a common drainage system into the Arabian Sea: the Jebel Qara limestone massif and the coastal plain of Salalah. Neogene to Quaternary tectonic activity controlled the formation of an extensive system of faults and caused the uplift of the Jebel Qara, forming structural escarpments. The massif underwent karstification and subsequent linear erosion. Today the Jebel is cut by a dendritic net of dry valleys, occasionally dammed by calcareous tufa dams. The transition between the southern escarpment of the Jebel and the plain below displays flat alluvial fans, bordered by a strip of beachrock, coastal dunes, and coastal lagoons, located in correspondence to estuaries. Dramatic soil erosion is evident, linked to intense human-triggered zoogeomorphological processes started in the Mid-Late Holocene after the introduction of pastoral land-use.

Wildlife monitoring is often used by biologists and ecologists to acquire information about animals and their natural habitats. In survey programs, specialists collect environmental information to infer about animal population status and their variations over time. The main goal of such programs is to identify environmental problems in early stages. However, acquiring the necessary data for this purpose is a manual work and must be carried out by groups of experts in areas of di cult access during long periods of time. In this context, Wireless Sensor Networks (WSNs) are useful alternatives to alleviate the manual work. Such networks are made up of small sensors with transmission, storage, and local processing capabilities. These networks enable bioacoustic methods for automatic species recognition to be embedded in the sensor nodes in order to automate and simplify the monitoring task. Since animal sounds usually provide a species ngerprint, it can be used to recognize the presence...

This works aims at applying a methodology to characterize the fracture network in granitic rocks in a pilot area on the South of Sardinia. The fracture network has been characterized through a multiscale approach using digital photogrammetry and field measurements of fracture parameters. The digital photogrammetry allowed to generate a digital elevation model (DEM) of high resolution (5m), orthophotos and then the digitalization of over 900 lineaments. The orientation and the length were calculated for the lineaments. The fractures field survey provided complementary information regarding to the orientation, the aperture, the spacing and the roughness of the fractures.

Des-Cubierta Cave, part of the Calvero de la Higuera complex, is situated in the intramountainous upper valley of the Lozoya River within the Guadarrama Range. The cave's geological, palaeontological, and archaeological record reveals a complex history of sedimentary and anthropogenic processes spanning hundreds of thousands of years, represented in 12 lithostratigraphic units. Among these, Unit 3 stands out for its archaeological significance, containing evidence of Neanderthal activity, including Mousterian lithic tools and an unusual assemblage of large mammal crania, which suggests symbolic behaviour. Geological data indicate that Unit 3 was deposited during cold periods (MIS 4) through multiple rockfall episodes, implying that these symbolic practices persisted across generations. The cave's geomorphology points to a possible Neanderthal entrance via a side opening created by erosion in the southern part of the cave. This study enhances our understanding of Des-Cubierta Cave's geological development and the long-term Neanderthal occupations, offering valuable insights into their symbolic and cultural behaviours.

Bu çalışmada Urganlı (Manisa) yöresinde çökelmeye devam eden termojen kökenli traverten çökelleri morfolojik özelliklerine göre ayırtlanmış ve tektonizma ile olan ilişkisi ortaya konulmuştur. Urganlı termojen kökenli traverten çökelleri morfolojik özellikleri dikkate alınarak; tabakalı, fay önü, damar tipi, tümsek-teras tipi, sırt tipi ve kanal tipi travertenler olarak altı sınıfa ayrılmıştır. Bölgedeki tüm traverten morfolojileri fayların kontrolünde gelişmiştir. Saha gözlemlerinden elde edilen veriler sahanın traverten oluşum başlangıcında Kuzey-Güney yönlü bir genleşmenin varlığını ortaya koymaktadır. Sonraki dönemde bu genleşme Doğu-Batı yönlü gelişerek Kuzey-Güney doğrultulu traverten damarlarının çökelimine neden olmuştur. Yakın geçmişte ise Kuzey-Güney yönlü genleşme etkisini sürdürdüğünü Doğu-Batı doğrultulu sırt tipi travertenlerin gelişimiyle anlaşılmaktadır. Derin elektrik sondaj ve mekanik sondaj verileri ile temelin (Paleozoyik-Mesozoyik) Paleo-morfolojisi incelendiğinde yine Kuzey-Güney ve Doğu-Batı faylarının etkisinde çalışma alanının kuzey batısına doğru yükseldiği, güneydoğusuna doğru düştüğü saptanmıştır.

L'étude porte sur le fonctionnement et l'évolution morphodynamique d'une creuse, ravin d'ordre kilométrique qui entaille souvent le fond des vallons élémentaires des plateaux crayeux de l'Artois et de la Picardie. L approche morphosédimentaire exploite les données de 3 coupes (stratigraphie, analyses micromorphologiques), réparties sur une section d'environ 500 m et replacées dans leur contexte géomorphologique (cartographie sur la base d'un MNT, profil en long). La reconnaissance de formations caractéristiques (loess lités et paléosol) et d'artéfacts médiévaux permet de proposer une chronologie débutant à 30 000 BP. La stratigraphie et l'analyse du modelé démontrent le caractère fluviatile de l'incision de la creuse. Deux phases principales d'incision sont repérées et associées à un style fluvial méandriforme. Les phases de remblaiement, au moins d'époque médiévale pour la dernière, correspondent à des évènements épisodiques et violents de type torrentiel. Les versantsjouent un rôle importart, déiivrant en abondance des loess qui colmatent aujourd'hui le fond du ravin.

The abundance of karst depressions in Yucatán has been widely recognized, but they have not been classified or quantified despite their importance in land-use planning. Our objective was to study the types and areas of the sinkholes, uvalas, and poljes and identify their patterns of spatial distribution. We used 58 topographic maps (1:50,000) from INEGI, from which we extracted the depressions and bodies of water. For typology, we used a circularity index and the shape and area of the depressions. For single-density analysis, we extracted the centroids and added an inventory of karst features (cenotes, caves). We counted 6717 depressions with a total area of 454 km 2 and 750 karst features. We identified 4620 dolines (34 km 2 ), mainly in plateaus below 30 masl. In number, they are followed by uvalas (2021) and poljes ( ), occupying together a similar area (210 km 2 ) and dominating in elevations higher than 30 masl. Eighty percent of the dolines were automatically labeled. The density of depressions allowed us to identify the "ring of cenotes" and the "field of dolines" according to two main types of factors, structural and climatic. The typology and density of the depressions could be used as geomorphological differentiation criteria in the vast plateaus of central and eastern parts of the state.

The tourism industry is profoundly influenced by various external factors, including pandemics, natural disasters, geopolitical tensions, economic crises, and climate change. Each of these factors presents unique challenges, necessitating tailored risk management strategies. This study investigates the impact of natural hazards on highland destinations, using the Shovi landslide that occurred in August 2023 in Georgia as a case study. Given the vulnerability of highland regions to natural disasters, a comprehensive analysis is essential. This research employs a triangulation methodology that combines a systematic literature review, statistical data analysis, and an online questionnaire to assess tourists' perceptions of safety and their behavioural responses following the landslide. Findings indicate that natural disasters have multidimensional impacts—financial, infrastructural, human, and environmental—significantly affecting the tourism industry. The study highlights the necessity of effective management and mitigation strategies to bolster tourism resilience in the region. By situating the Shovi landslide within the broader context of highland tourism, this research contributes to the academic discourse on disaster impacts and recovery. It identifies critical gaps in the literature and offers empirical evidence for developing crisis management frameworks tailored to highland destinations. This study aims to advance understanding of the interplay between natural disasters and tourism dynamics, providing a foundation for future scholarly inquiry in this field.

GEARH d.o.o., Slovenia The Dinaric karst is one of the most typical karst areas in the world where the karst phenomena are widespread and well-developed. This area is also particularly interesting because its mountainous parts experienced glacial conditions during the Quaternary cold stages and hence a glaciokarst type of landscape developed. The Snežnik Mountain (1796 m asl) in the southern part of Slovenia is a high karst plateau that shows significant glacial modification with the majority of glacial deposits being deposited between 900 and 1200 m asl. Here we present a study of the Praprotna draga closed depression, which is one of the largest karst depressions in Snežnik with an area of approximately 3.4 km2 and a maximum depth of 140 m. Its western slopes are characterized by undulated moraine morphology and alluvial fans starting from bellow moraines are filling the entire floor of the depression. This study aims to improve understanding of spatial and chronological relationship between glacial, paraglacial and ice-proximal outwash dynamics in the Dinaric karst environment. Therefore, we reveal the origin, geometry and age of deposits in Praprotna draga using geomorphological, sedimentological, geophysical and cosmogenic dating approaches. The spatial distribution and geometry of moraines point to two glacial advances with an altitudinal difference of about 140 m. This two-phase interpretation is also supported with the electrical resistivity tomography (ERT) measurements performed along one of the alluvial fans, which show a diamicton-like sedimentary body buried below alluvial deposits. Another ERT profile was measured over the moraine ridge in order to obtain the significant resistivity values of till deposits in this area and compare them with resistivity values of diamicton buried bellow alluvium. Alluvial deposits in the mid fan zone were sampled for cosmogenic 36Cl analysis of amalgamated carbonate pebbles. The depth profile of 36Cl concentrations leads to a minimum age of the alluvial deposit of 11.7 ± 1.2 kyr when assuming no denudation and up to an age of 13.9 ± 2.2 kyr for 30 mm/yr of soil denudation. This suggests the alluvial material was deposited during Late glacial period, in transition from glacial to non-glacial conditions, and subsequently allow us to interpret the timing of the final glacier retreat in the Snežnik Mountain.

A survey of caves in siliciclastic rocks of Brazil revealed at least 26 areas with caves, with a total of 170 mapped caves, ranging from several meters to about 3.5km of planimetric development. They occur mainly in Phanerozoic sandstones and Proterozoic quartzites of cratonic covers and fold belts. Collapse and dissolution dolines, collapse valleys, as well as kamenitzas, karren and sinkholes are typical surface features. Topographical karst forms are better developed over quartzites than sandstones. Two main morphological patterns of caves are recognized. In sandstones the dominant morphology consists of horizontal cone shaped conduits, which combine to form caves of up to 400m of extention. Almost all such caves contain springs with underground creeks. When such conduits intersect, breakdown chambers form. Caves with underground rivers associated with insurgences and ressurgences are less frequent. The second pattern, which occurs in quartzites, comprises integrated conduits of varied shapes, resembling the morphology of limestone cave systems. Of greater planimetric development (up to 3km), these caves exhibit large vadose entrenchments, breakdown halls and underground rivers. Some contain opal speleothems, such as stalactites, stalagmites, flowstones, rimstone dams and crusts.A speleogenetic model is proposed, in which a combination of piping and dissolution processes work in concurrence. In sandstones, arenization and piping close to the water table are dominant, resulting in pseudokarst features, whereas in quartzites, dissolution of quartz grains along groundwater flow routes is able to act during a longer time, resulting in forms closer to typical karst features View publication stats
