Ground movement can be measured from space by comparing satellite images acquired at different times using a technique known as InSAR. The InSAR Svalbard service provides baseline information on where and how the ground surface is moving, supporting geohazard management, land-use planning, and climate change adaptation, and helping assess impacts on infrastructure and human activities. While such services exist elsewhere, this is the first of its kind in the Arctic.

Monitoring long-term surface subsidence induced by ground ice thaw across the pan-Arctic is crucial to detect permafrost changes and assess impacts caused by recent atmospheric warming. Using Sentinel-1 satellite radar data, we successfully measured subsidence rates in Siberia’s Lena Delta and found that they vary remarkably among the three main geomorphological units. To enable continuous, large-scale monitoring, satellite data records must maintain coherence from one summer season to the next.

We mapped glacier outlines in Austria using recent, high resolution imagery. The resulting glacier inventory provides an update on glacier area in Austria in 2021-2023. More than 30% of glacier area was lost and 95 glaciers have disappeared since the mid-2000s. Glacier recession is accelerating and regular updates to glacier inventories are needed to understand downstream changes to the hydrological system, quantify glacier mass loss, and support planning and adaptation measures.

Climate change increases landslide risk in cold regions. We analyzed 12 years of GPS, borehole, water, and seismic data from two landslides in Arctic Norway, one with permafrost and one without. Both accelerate in spring and autumn due to water infiltration. One slip zone shows increasing snowmelt sensitivity while seismic data reveal seasonal stiffness changes. Results advance understanding of water-driven landslide dynamics in Arctic climates.

Ice-debris complexes (IDC) are common, but their evolution remains poorly understood. We investigated 4 IDCs and identified 3 major zones: a glacier, a glacier-affected, and a periglacial zone. Although glacier-affected and periglacial zones cover much smaller areas than glaciers, their ice volume losses are comparable. IDCs can evolve through multiple pathways, incl. gradual transformation of glacier into rock glaciers and the advance or embedding of glaciers onto pre-existing rock glaciers.

Juvfonne is a small ice patch and contains the oldest ice dated in Norway so far. Juvfonne prevails due to drifting snow and can fill up after years with surface lowering. However, the reduction in area and volume over the period 2010–2025 reveal that Juvfonne is vulnerable to the current warming. Ice thickness measurements conducted in September 2025 reveal a current maximum thickness of less than 9 meters and an interpolated mean thickness of < 3 meters.

We mapped monthly glacier flow speeds in the Kangri Karpo region from 2015 to 2024 by combining measurements from several satellites and a drone survey. The merged maps are more complete and detailed than maps from any single source, with fewer gaps caused by clouds or difficult terrain. The results show where glaciers move fastest, how their speed changes through the year, and which glaciers have been speeding up or slowing down over the past decade.

We investigated a hanging glacier in the Swiss Alps to resolve poorly known geometry, thermal conditions and response to climate forcing. Using up to five years of data from drone surveys, ground penetrating radar, temperature measurements and modelling, we show the glacier lost up to 7 m (20–45 % of the 2021 thickness), while the surrounding permafrost is degrading. The glacier is transitioning towards polythermal conditions, due to meltwater infiltration, increasing future instability risk.

The latest satellite technology with longer wavelength radar improves our ability to detect and monitor large alpine rock slope instabilities. This approach works better than current satellite systems in forested areas and on fast-moving slopes, giving experts more reliable data to understand these major hazards. Our results from three locations in Italy and Switzerland also provide important recommendations for the preparation of future satellite radar missions.

Dry Andean (debris-covered) glaciers and rock glaciers are essential to river runoff by contributing meltwaters in this extremely arid area. We quantify surface lowering for 19 glaciers and 3 debris-covered glaciers, and unchanged velocities for 47 rock glaciers in a ground-truthed and Pléiades satellite imagery based integrative glacier-permafrost study on catchment-scale for 2019-2025. For this period, our findings indicate glacial decline next to permafrost stability.

By analysing 30 years of satellite SAR (Synthetic Aperture Radar) data, we have found that the number of glacier surges over Svalbard has tripled since 2015. We show that this increase is unlikely to be explained solely by improvements in data quality or by random fluctuations in surge frequency, suggesting that this trend is caused by an external forcing mechanism. Given our incomplete understanding of surge initiation, the cause of the observed threefold increase remains however uncertain.

Many mountain glaciers around the world flow into lakes – exactly how many however, has never been mapped. Across a large team of experts we have now identified all glaciers that end in lakes. Only about 1% do so, but they are generally larger than those which end on land. This is important to understand, as lakes can influence the behaviour of glacier ice, including how fast it disappears. This new dataset allows us to better model glaciers at a global scale, accounting for the effect of lakes.

Snow stored in winter snowpacks supplies water to rivers that millions of people depend on. As warming reduces snow amounts, we studied whether melting snow still matters for river flow. Using long records from river basins on four continents, and cause and effect analysis, we found that in some basins melting snow can become more important for river flow even when less snow is available.

In permafrost environments, the ground surface moves due to the formation and melt of ice in the ground. This study compares ground surface displacements measured from satellite images against field data of ground ice contents. We find good agreement between the detected seasonal subsidence and observed ground ice melt. Our results show the potential of satellite remote sensing for mapping ground ice variability, but also indicate that ice in excess of the pore space must be considered.

A deadly landslide struck Wrangell Island, Alaska, in November 2023, traveling over a kilometer and claiming six lives. Our study shows it was likely triggered by moderate rainfall combined with rapid snowmelt and drainage from a ridgetop wetland, which saturated deep soil deposits on a steep hillslope. The landslide grew unusually large as it entrained abundant soil. Findings highlight the role of storm patterns, geology, and hydrology in driving future landslide hazards in SE Alaska.

We created the first comprehensive inventory of Peru's rock glaciers: 2338 landforms in the Andes and filling the information gap in this mountainous region. Using satellite imagery, we mapped their distribution, finding most of them in southern Peru, above 4800 m a.s.l. and conditioned mainly by low temperature and precipitation. This dataset helps scientists to follow the evolution of permafrost and local planners to manage water resources and risks in the mountains.

This study establishes a methodology for the study of slow-moving rock glaciers in marginal permafrost and provides the basic knowledge for understanding rock glaciers in South East Europe. By using a combination of different methods (remote sensing, geophysical survey, thermal measurements), we found out that, on the transitional rock glaciers, low ground ice content (i.e. below 20 %) produces horizontal displacements of up to 3 cm per year.

Our study, focused on South Tyrol (NE Italy), develops an updated and comprehensive activity classification system for all rock glaciers in the current regional inventory. Using multisource products, we integrate climatic, morphological, and differential interferometric synthetic aperture radar (DInSAR) data in replicable routines and multivariate statistical methods, producing a comprehensive classification based on the updated Rock Glacier Inventories and Kinematic (RGIK) 2023 guidelines. Results leave only 3.5 % of the features non-classified, as opposed to 13–18.5 % in previous studies.

Rock glaciers are landforms generated by the creep of frozen ground (permafrost) in cold-climate mountains. Mapping rock glaciers contributes to documenting the distribution and the dynamics of mountain permafrost. We compiled inventories documenting the location, the characteristics, and the extent of rock glaciers in 12 mountain regions around the world. In each region, a team of operators performed the work following common rules and agreed on final solutions when discrepancies were identified.

This study presents a robust methodological approach to detect and analyse rock glacier kinematics using Landsat 7/Landsat 8 imagery. In the semiarid Andes, 382 landforms were monitored, showing an average velocity of 0.37 ± 0.07 m yr⁻¹ over 24 years, with rock glaciers moving 23 % faster. Results demonstrate the feasibility of using medium-resolution optical imagery, combined with radar interferometry, to monitor rock glacier kinematics with widely available satellite datasets.

Ribbed moraines are a common, but poorly understood landform within formerly glaciated regions. There are many competing theories for their formation. As such, this paper addresses some of these theories by taking modelled ice conditions and physical characteristics of the landscapes in which they form and, then comparing them to the location of ribbed moraines. Using this we can identify conditions where ribbed moraines are more often present, and therefore we identify the most likely theories.

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.

We reconstruct the evolution of terminus position, ice thickness, and surface flow velocity of the reference Abramov glacier (Kyrgyzstan) from 1968 to present. We describe a front pulsation in the early 2000s and the multi-annual present-day buildup of a new pulsation. Such dynamic instabilities can challenge the representativity of Abramov as a reference glacier. For our work we used satellite‑based optical remote sensing from multiple platforms, including recently declassified archives.

This study highlights the importance of a multi-method and multi-disciplinary approach to better understand the influence of the internal structure of the Gruben glacier-forefield-connected rock glacier and adjacent debris-covered glacier on their driving thermo-mechanical processes and associated surface dynamics. We were able to discriminate glacial from periglacial processes as their spatio-temporal patterns of surface dynamics and geophysical signatures are (mostly) different.

Satellites have made it possible to observe glacier elevation changes from all around the world. In the present study, we compared the results produced from two different types of satellite data between different research groups and against validation measurements from aeroplanes. We found a large spread between individual results but showed that the group ensemble can be used to reliably estimate glacier elevation changes and related errors from satellite data.

In this paper, we use machine learning to automatically outline landforms based on their characteristics. We test several methods to identify the most accurate and then proceed to develop the most accurate to improve its accuracy further. We manage to outline landforms with 65 %–75 % accuracy, at a resolution of 10 m, thanks to high-quality/high-resolution elevation data. We find that it is possible to run this method at a country scale to quickly produce landform inventories for future studies.

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.

Permafrost (permanently frozen ground) is widespread in the mountains of Norway and Iceland. Several boreholes were drilled after 1999 for long-term permafrost monitoring. We document a strong warming of permafrost, including the development of unfrozen bodies in the permafrost. Warming and degradation of mountain permafrost may lead to more natural hazards.

Because glaciers are crucial freshwater sources in the lowlands surrounding High Mountain Asia, constraining short-term glacier mass changes is essential. We investigate the potential of state-of-the-art satellite elevation data to measure glacier mass changes in two selected regions. The results demonstrate the ability of our dataset to characterize glacier changes of different magnitudes, allowing for an increase in the number of inaccessible glaciers that can be readily monitored.

This study looked at under the ground on Svalbard, an archipelago close to the North Pole. We found something very surprising – there is water under the all year around frozen soil. This was not known before. This water could be used for drinking if we manage it carefully. This is important because getting clean drinking water is very difficult in Svalbard, and other Arctic places. Also, because the climate is getting warmer, there might be even more water underground in the future.

The South Col Glacier is a small body of ice and snow located on the southern ridge of Mt. Everest. A recent study proposed that South Col Glacier is rapidly losing mass. In this study, we examined the glacier thickness change for the period 1984–2017 and found no thickness change. To reconcile these results, we investigate wind erosion and surface energy and mass balance and find that melt is unlikely a dominant process, contrary to previous findings.

We assess spatio-temporal permafrost variations in selected rock walls in Norway over the last 120 years. Ground temperature is modelled using the two-dimensional ground heat flux model CryoGrid 2D along nine profiles. Permafrost probably occurs at most sites. All simulations show increasing ground temperature from the 1980s. Our simulations show that rock wall permafrost with a temperature of −1 °C at 20 m depth could thaw at this depth within 50 years.

The Vinschgau Shear Zone (VSZ) is one of the largest and most significant shear zones developed within the Late Cretaceous thrust stack in the Austroalpine domain of the eastern Alps. 40Ar / 39Ar geochronology constrains the activity of the VSZ between 97 and 80 Ma. The decreasing vorticity towards the core of the shear zone, coupled with the younging of mylonites, points to a shear thinning behavior. The deepest units of the Eo-Alpine orogenic wedge were exhumed along the VSZ.

The CryoGrid community model is a new tool for simulating ground temperatures and the water and ice balance in cold regions. It is a modular design, which makes it possible to test different schemes to simulate, for example, permafrost ground in an efficient way. The model contains tools to simulate frozen and unfrozen ground, snow, glaciers, and other massive ice bodies, as well as water bodies.

We present a novel data-driven modelling approach to determine season-specific critical precipitation conditions for landslide occurrence. It is shown that the amount of precipitation required to trigger a landslide in South Tyrol varies from season to season. In summer, a higher amount of preparatory precipitation is required to trigger a landslide, probably due to denser vegetation and higher temperatures. We derive dynamic thresholds that directly relate to hit rates and false-alarm rates.

The panoramic cameras (PCs) on board Hexagon KH-9 satellite missions from 1971–1984 captured very high-resolution stereo imagery with up to 60 cm spatial resolution. This study explores the potential of this imagery for glacier mapping and change estimation. The high resolution of KH-9PC leads to higher-quality DEMs which better resolve the accumulation region of glaciers in comparison to the KH-9 mapping camera, and KH-9PC imagery can be useful in several Earth observation applications.

In this study, first we generated inventories which allowed us to systematically detect glacier change patterns in the Karakoram range. We found that, by the 2020s, there were approximately 10 500 glaciers in the Karakoram mountains covering an area of 22 510.73 km2, of which ~ 10.2 % is covered by debris. During the past 30 years (from 1990 to 2020), the total glacier cover area in Karakoram remained relatively stable, with a slight increase in area of 23.5 km2.

One of the reasons for lower ground temperatures in coarse, blocky terrain is a low or varying soil moisture content, which most permafrost modelling studies did not take into account. We used the CryoGrid community model to successfully simulate this effect and found markedly lower temperatures in well-drained, blocky deposits compared to other set-ups. The inclusion of this drainage effect is another step towards a better model representation of blocky mountain terrain in permafrost regions.

This study demonstrates how the threat of a very large outburst from a future lake can be feasibly assessed alongside that from current lakes to inform disaster risk management within a transboundary basin between Tibet and Nepal. Results show that engineering measures and early warning systems would need to be coupled with effective land use zoning and programmes to strengthen local response capacities in order to effectively reduce the risk associated with current and future outburst events.

In northern Norway we have observed several rock glaciers at sea level. Rock glaciers are landforms that only form under the influence of permafrost, which is frozen ground. Our investigations show that the rock glaciers are probably not active under the current climate but most likely were active in the recent past. This shows how the Arctic now changes due to climate changes and also how similar areas in currently colder climates will change in the future.

Rock glaciers are some of the most frequently occurring landforms containing ice in mountain environments. Here, we use field observations, analysis of aerial and satellite images, and dating methods to investigate the activity of the rock glacier of the Vallon de la Route in the French Alps. Our results suggest that the rock glacier is characterized by two major episodes of activity and that the rock glacier system promotes the maintenance of mountain erosion.

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.

We intensely investigated the Gruben site in the Swiss Alps, where glaciers and permafrost landforms closely interact, to better understand cold-climate environments. By the interpretation of air photos from 5 decades, we describe long-term developments of the existing landforms. In combination with high-resolution positioning measurements and ground surface temperatures, we were also able to link these to short-term changes and describe different landform responses to climate forcing.

The Arctic has large areas of small mounds that are caused by ice lifting up the soil. Snow blown by wind gathers in hollows next to these mounds, insulating them in winter. The hollows tend to be wetter, and thus the soil absorbs more heat in summer. The warm wet soil in the hollows decomposes, releasing methane. We have made a model of this, and we have tested how it behaves and whether it looks like sites in Scandinavia and Siberia. Sometimes we get more methane than a model without mounds.

This work uses satellite and aerial data to study glaciers and rock glacier changes in La Laguna catchment within the semi-arid Andes of Chile, where ice melt is an important factor in river flow. The results show the rate of ice loss of Tapado Glacier has been increasing since the 1950s, which possibly relates to a dryer, warmer climate over the previous decades. Several rock glaciers show high surface velocities and elevation changes between 2012 and 2020, indicating they may be ice-rich.

Surging glaciers show cyclical changes in flow behavior – between slow and fast flow – and can have drastic impacts on settlements in their vicinity.
One of the clusters of surging glaciers worldwide is High Mountain Asia (HMA).
We present an inventory of surging glaciers in HMA, identified from satellite imagery. We show that the number of surging glaciers was underestimated and that they represent 20 % of the area covered by glaciers in HMA, before discussing new physics for glacier surges.

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.

About 10 % of Himalayan glaciers flow directly into lakes. This study finds, using satellite imagery, that such glaciers show higher flow velocities than glaciers without ice–lake contact. In particular near the glacier tongue the impact of a lake on the glacier flow can be dramatic. The development of current and new meltwater bodies will influence the flow of an increasing number of Himalayan glaciers in the future, a scenario not currently considered in regional ice loss projections.

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.

Short summary
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.
