Article
We present a regional inventory of rock glaciers (n = 1514) and protalus ramparts (228) for the Lombardy region, central Italian Alps. To identify and classify the landforms we inspect three sequential air-orthophoto mosaics and a 2 m-DSM, and conduct confirmatory field work. The inventory forms an empirical basis to analyze: (i) the relative contr...

The variability of glacier response to atmospheric temperature rise in different topo-climatic settings is still a matter of debate. To address this question in the Central Italian Alps, we compile a post-LIA (Little Ice Age) multitemporal glacier inventory (1860–1954–1990–2003–2007) along a latitudinal transect that originates north of the contine...
Article
The Plator rock glacier is the first such landform identified in the Italian Alps that shows destabilised behaviour. Analysis of six sets of sequential orthophotographs from 1981 to 2012 reveals an exceptional advance of the rock glacier front (92.1 m) and a horizontal velocity up to 4m a-1 in different zones. The spatial variability of kinematics...
Article
Across the northern European Alps, a long tradition of Quaternary studies has constrained post-LGM (Last Glacial Maximum) landscape history. The same picture remains largely unknown for the southern portion of the orogen. In this work, starting from existing ¹⁰Be exposure dating of three boulders in Val Viola, Central Italian Alps, we present the f...
Article
This paper aims to evaluate sources of uncertainty and variability associated with rock glacier inventories compiled from remotely sensed imagery. To this end, we ran three mapping exercises in Kaiserbergtal, Austria. To evaluate interactions between mapping style and imagery resolution, we asked six operators to map and assess the degree of activi...

Una stagione di accumulo eccezionalmente secca, aggravata da un mese di maggio dalle temperature elevatissime, ha provocato una scarsità di neve senza precedenti sui ghiacciai lombardi
Article
Full-text available
La recessione dei ghiacciai è ormai un fenomeno tanto noto quanto evidente. In particolare nell’ultimo trentennio, i ghiacciai alpini stanno subendo un incisivo e rapido ridimensionamento dovuto principalmente all’innalzamento delle temperature. Se da un punto di vista scientifico monitorare le variazioni glaciali consente di documentare e quantifi...

Permafrost distribution in the European Alps has been modelled at regional scale but, given its high spatial variability, in situ measurements remain crucial to calibrate the model outputs and to monitor the permafrost evolution. Ground surface temperature (GST) is defined as the near surface temperature of the ground and is typically measured few...
Presentation
Full-text available
Terrestrial time-lapse images have been mainly used to improve glacier monitoring by measuring glacier flow, snow and ice albedo, mass and energy balance and to investigate calving and surging processes. Accelerated videos of time-lapse image series are extremely powerful tools to visualize the effects of climate change on glaciers. After the pione...

The interplay of tectonic and climatic forcing in the development of Alpine deep-seated gravitational slope deformations (DSGSD) is still poorly understood. We investigate a giant DSGSD affecting the Piz Dora slope (Val Müstair, Switzerland) by geological, structural and geomorphological analyses, spaceborne SAR interferometry and numerical modelli...

In latter years, because of the climate change and the related transition from cold to warm based ice in high elevation glaciers, avalanches due to the collapses of hanging glaciers have raised importance and interest. In this work, we present the case study of Palòn de la Mare, a mountain glacier with a secondary hanging snout, which frequently br...

In this report, winter mass balances of eight glaciers in the Lombardy region (Central Italian Alps) are presented for the season 2017/2018. Data were provided by the Glaciological Service of Lombardy (Servizio Glaciologico Lombardo, SGL) network. The 2017/18 point winter balances in the Lombardy region are the most negative since 2007 in terms of...
Article
To improve current understanding of ongoing deglaciation dynamics in relation to climatic forcing, it is critical to build long-term series of climate and glacier changes. This task is typically hampered by availability and resolution of Quaternary glacier paleo-reconstructions. To explore opportunities and challenges, we present a case study from...
Article
In order to assess the climate–glacier relationship in the Southern European Alps, two small glaciers in Lombardy, Suretta Sud and Lupo, have been chosen for investigation. GPS profiling in 2016 allowed the determination of elevation changes since 2007 and thus the determination of the glacier mass balance using the geodetic method. Older maps have...
Article
Rock avalanches are large flow-like movements of fragmented rock that can cause extensive and rapid topographic changes, for which very few quantitative data are available. This paper analyses the geomorphological and hydrological impact of the 3 million m3 Thurwieser rock avalanche (2004, Italian Central Alps) by using Terrestrial Laser Scanner, a...

We present an integrated approach that aims to: (i) document the spatial distribution of mass-wasting activity and sediment production in the Saldur River basin (97 km2); (ii) detect causal linkages between mass-wasting intensity and the potential spatial distribution of discontinuous permafrost; (iii) identify source-to-sink colluvial sedimentary...
Conference Paper
While it is widely recognized that deglaciation and permafrost degradation can induce generalized instability in steep mountain terrain, beyond the documentation of single catastrophic mass-wasting events, there appears to be little empirical work on how the colluvial sediment cascade functions under conditions of increasing atmospheric temperature...

The Lombardy Alps, with a surface of 2148 km2 above 2000 m a.s.l. (9% of the total) represents an important portion of the southern side of the orogen. For encompassing a variety of tectonic and climatic regimes, they represent an interesting area to examine environmental controls on periglacial processes. Today, technological developments in remot...
