The Monte Crenone rock avalanche of 1513 is well known on the southern side of the Alps because in 1515 it generated the largest inundation that has occurred in Switzerland in the Common Era, the Buzza di Biasca. New geological and historical observations allowed the setup of a numerical model of this major event, permitting a better definition of the chain of consequences that affected the alluvial plain of the river Ticino from Biasca to Lake Maggiore between the 16th and the 19th century.

The paper presents the results of recent geoarchaeological studies on the Ticino river alluvial plain. The sedimentological descriptions are combined with archaeological observations and constrained with radiocarbon dating. This approach, together with data from previous research and historical sources, provides an interesting overview of the eveolution of Ticino river morphosedimentary dynamics in relation to human settlements since the Neolithic.

Exposure ages make it possible to determine the time of weathering of a rock surface. They can be determined from rebound values measured with the Schmidt hammer and calibrated on surfaces of known age, defined in this study thanks to historical cartography and two mule tracks built in 300 and 1250 CE, which allowed us to reconstruct glacier fluctuations over the last 3 centuries in Val Scaradra and to define the time of deglaciation and rock glacier development in the Splügenpass region.

In the scientific literature, “protalus ramparts” can designate both a nivo-gravitational landform (also called “pronival ramparts”) and a permafrost-related landform. Thanks to a selection of eight major diagnostic criteria defined from observations carried out in the Swiss Alps, it was highlighted that the structure, ice content and creep dynamics of protalus ramparts are the same as many rock glaciers. Protalus rampart were therefore defined simply as a (small) active talus rock glacier.

Some examples of 3-D digital mapping for Quaternary geological and geomorphological cartography are presented in this paper. Examples concern in particular the Quaternary geological cartography around the well-know Flims rockslide area (Graubünden), performed in the framework of the GeoCover project launched by the Swiss Geological Survey, and the landslide and glacial/periglacial landform mapping and inventorying in the southern Swiss Alps (Ticino) for assessing the slope tectonic activity.

Mapping soil moisture in Arctic permafrost regions is crucial for various activities, but it is challenging with typical satellite methods due to the landscape's diversity. Seasonal freezing and thawing cause the ground to periodically rise and subside. Our research demonstrates that this seasonal ground settlement, measured with Sentinel-1 satellite data, is larger in areas with wetter soils. This method helps to monitor permafrost degradation.

Traditional inventories display high uncertainty in discriminating between intact (permafrost-bearing) and relict (devoid) rock glaciers (RGs). Integration of InSAR-based kinematics in South Tyrol affords uncertainty reduction and depicts a broad elevation belt of relict–intact coexistence. RG velocity and moving area (MA) cover increase linearly with elevation up to an inflection at 2600–2800 m a.s.l., which we regard as a signature of sporadic-to-discontinuous permafrost transition.

We present the guidelines developed by the IPA Action Group and within the ESA Permafrost CCI project to include InSAR-based kinematic information in rock glacier inventories. Nine operators applied these guidelines to 11 regions worldwide; more than 3600 rock glaciers are classified according to their kinematics. We test and demonstrate the feasibility of applying common rules to produce homogeneous kinematic inventories at global scale, useful for hydrological and climate change purposes.

Glacier surges are widespread in the Karakoram and have been intensely studied using satellite data and DEMs. We use time series of such datasets to study three glacier surges in the same region of the Karakoram. We found strongly contrasting advance rates and flow velocities, maximum velocities of 30 m d−1, and a change in the surge mechanism during a surge. A sensor comparison revealed good agreement, but steep terrain and the two smaller glaciers caused limitations for some of them.

Knowledge on surface velocity of glaciers and ice caps contributes to a better understanding of a wide range of processes related to glacier dynamics, mass change and response to climate. Based on the release of historical satellite radar data from various space agencies we compiled nearly complete mosaics of winter ice surface velocities for the 1990's over the Eastern Arctic. Compared to the present state, we observe a general increase of ice velocities along with a retreat of glacier fronts.

We present a map of rock glacier motion over parts of the northern Tien Shan and time series of surface speed for six of them over almost 70 years.
This is by far the most detailed investigation of this kind available for central Asia.
We detect a 2- to 4-fold increase in rock glacier motion between the 1950s and present, which we attribute to atmospheric warming.
Relative to the shrinking glaciers in the region, this implies increased importance of periglacial sediment transport.

The Venice coastland forms the major low-lying area in Italy and encompasses a variety of environments, such as farmlands, estuaries, deltas, lagoons and urbanized areas. Since most of the territory lies at a ground elevation below or slightly above the mean sea-level, also a few mm/yr of land subsidence can seriously impacts on the coastal system. In this study, we present an analysis of the vulnerability to relative sea-level rise (RSLR) considering an uneven land subsidence distribution.

Knowledge about the size and location of glaciers is essential to understand impacts of climatic changes on the natural environment. Therefore, we have produced an inventory of all glaciers in some of the largest glacierized mountain regions worldwide. Many large glaciers are covered by a rock (debris) layer, which also changes their reaction to climatic changes. Thus, we have also mapped this debris layer for all glaciers. We have mapped almost 28000 glaciers covering ~35000 km2.

The strong atmospheric warming observed since the 1990s in polar regions requires quantifying the contribution to sea level rise of glaciers and ice caps, but for large areas we do not have much information on ice dynamic fluctuations. The recent increase in satellite data opens up new possibilities to monitor ice flow. We observed over Stonebreen on Edgeøya (Svalbard) a strong increase since 2012 in ice surface velocity along with a decrease in volume and an advance in frontal extension.

Eighty regular TerraSAR-X acquisitions over the 2008-2011 period significantly improve the subsidence monitoring at the Venice coastland. Settlements of 30-35 mm/yr have been detected at the three lagoon inlets in correspondence of the MoSE works. The Venice and Chioggia historical centers show local sinking bowls up to 10 mm/yr connected with the construction of new large buildings or restoration works. In the city of Venice, the mean subsidence of 1.1±1.0 mm/yr confirms its general stability.

The study is a geomorphological analysis of Djebel Dahar, in south-eastern Tunisia, carried out as the basis for a UNESCO Global Geopark. We made a synthesis of the geographical, geological and geomorphological context of the area, proposed a delimitation for the future geopark, based on geological and geomorphological characteristics, and established a preliminary list of geosites, indicating their scientific value and their potential for geotourism.

Soil quality depends on water availability for plants. Sandy soils with a poorly permeable layer (fragipan) are considered inept for agriculture. However they are cultivated in Namibia as they secure a minimum harvest during droughts. In order to understand the hydrological influence of fragipans in these soils, soil moisture content was measured. The results illustrate that the combination of sandy topsoil and shallow fragipan has beneficial effects on plant-available water during dry periods.

The Monte Crenone rock avalanche of 1513 is well known on the southern side of the Alps because in 1515 it generated the largest inundation that has occurred in Switzerland in the Common Era, the Buzza di Biasca. New geological and historical observations allowed the setup of a numerical model of this major event, permitting a better definition of the chain of consequences that affected the alluvial plain of the river Ticino from Biasca to Lake Maggiore between the 16th and the 19th century.

The paper presents the results of recent geoarchaeological studies on the Ticino river alluvial plain. The sedimentological descriptions are combined with archaeological observations and constrained with radiocarbon dating. This approach, together with data from previous research and historical sources, provides an interesting overview of the eveolution of Ticino river morphosedimentary dynamics in relation to human settlements since the Neolithic.

Exposure ages make it possible to determine the time of weathering of a rock surface. They can be determined from rebound values measured with the Schmidt hammer and calibrated on surfaces of known age, defined in this study thanks to historical cartography and two mule tracks built in 300 and 1250 CE, which allowed us to reconstruct glacier fluctuations over the last 3 centuries in Val Scaradra and to define the time of deglaciation and rock glacier development in the Splügenpass region.

In mountain environments, active geomorphological processes have a strong influence on plant diversity because they act as renovators for habitats of pioneer species. In this paper, we propose criteria to assess the ecological value of dynamic mountain geomorphosites. We show that the interest of plant communities and the influence of geomorphological processes on plant communities are fundamental criteria for assessing ecological value in an exhaustive and objective way.

Soil erosion by wind and water is a commonly recognized phenomenon on agricultural land. Erosion in forests is studied less and generally considered to be limited because of the soil protection by vegetation. However, trees, when toppled because of old age or wind, loosen a considerable amount of soil when their roots are pulled from the ground. In addition, the holes left in the ground act as collectors for water and concentrated runoff, causing significant soil loss on forested slopes.

A spatiotemporal reconstruction of slope movements on the edge of Lake Lucerne near the municipality of Horw, canton of Lucerne is presented. The reconstruction was realized by analyzing growth reactions of beech (Fagus sylvatica L.) and fir (Abies alba Mill.) trees growing on this slope. Results show that the area has been moving at least since 1948. A significant concentration of events was observed between 1990 and 2000 as well as after 2006.

This article studies the ice flow in the Valais region during the last glaciation (Würm) in detail. The numerical modelling shows a discrepancy of the height of the ice cap compared to the geomorphological evidence based on trimlines. However, geomorphological evidence at the Simplon Pass indicating an ice flow from the Rhone valley into the valley of Toce was confirmed. Furthermore it is shown that for this confirmation a sufficient ice thickness is obligatory.

During the last 45 years, about 100 people lost their lives in avalanches in the European Alps each year. Avalanche fatalities in settlements and on transportation corridors have considerably decreased since the 1970s. In contrast, the number of avalanche fatalities during recreational activities away from avalanche-secured terrain doubled between the 1960s and 1980s and has remained relatively stable since, despite a continuing strong increase in winter backcountry recreational activities.

Long-term borehole temperature monitoring in mountain permafrost environments is challenging under the hostile conditions reigning there. On the basis of data measured in the SLF borehole network we show situations where ground temperature data should be interpreted with caution. A selection of recently observed problems are discussed, and advantages and possible drawbacks of various solutions including data correction, measurement redundancy or alternate instrumentation are presented.

The erosion of and depositions on channel bed surfaces are instrumental to understanding debris flow processes. We present different methods and highlight their pro and cons. Terrestrial and airborne laser scanning, erosion sensors, cross sections and geomorphological mapping are compared. Two of these approaches are tested and applied in a torrent. The results indicate that the methods are associated with variable temporal and spatial resolution as well as data quality and invested effort.

In the scientific literature, “protalus ramparts” can designate both a nivo-gravitational landform (also called “pronival ramparts”) and a permafrost-related landform. Thanks to a selection of eight major diagnostic criteria defined from observations carried out in the Swiss Alps, it was highlighted that the structure, ice content and creep dynamics of protalus ramparts are the same as many rock glaciers. Protalus rampart were therefore defined simply as a (small) active talus rock glacier.

Alpine and mountain slopes represent important pathways that link high-altitude grazing areas to meadows and rangelands at lower elevations. Given the acute gradients associated with such environments, we hypothesize that terracettes act as efficient runoff conveyance routes that facilitate the movement of runoff and associated material during erosion events. This hypothesis was partially disproved during a series of rainfall/runoff simulations on a well-developed terracette system, however.

Short summary
A glacial lake outburst flood hazard assessment by satellite Earth observation and numerical modelling was done for the lakes linked to the Thangothang Chhu glacier, Chomolhari area (Bhutan), combining detailed geomorphological mapping, landslide and rock glacier inventories, as well as surface displacements quantified by satellite InSAR. Outburst scenario modelling revealed that only a flood wave can have an impact on the two human settlements located downslope of the glacier.
