Article
Full-text available
Large rock falls and rockslides represent a risk for human communities in mountainous areas as they can cause fatalities and destruction of settlements and infrastructures. Assessing the associated hazard requires constraining the time frequency of such events. Since large rockslides are not common, estimating their frequency requires recording the...
Chapter
Recent observations and geodetic measurements in the European Alps show that changes are occurring on rock glacier dynamics, ranging from moderate velocity variations to strong acceleration or even total collapse. These changes can be related to the ground temperature and to climate warming. In most cases, rock glaciers do not represent any serious...
Article
Full-text available
Alpine mountains are affected by significant geomorphological processes whose evolution is partly conditioned by permafrost warming: rockfalls of various volumes, destabilisation of rock glaciers, and cryokarst. These phenomena, because of their intensity, may generate risks for territories. This paper provides a synthesis of the knowledge about th...
Conference Paper
Full-text available
A 100 m deep borehole in mountain permafrost has been equipped with both a thermistor chain and a fiber optic cable for Distributed Temperature Sensing. The device permits to assess the resolution and accuracy of DTS measurements through the comparison of parallel DTS profiles and with classical sensors. First results show that a resolution in the...
Article
Full-text available
Rock glaciers-ice-rich creeping landforms typical of permafrost mountain ranges-can develop an anomalous landslide-like behaviour called destabilisation. This behaviour is characterised by failure mechanisms (including cracks and crevasses) and increases in displacement rates by one to two orders of magnitude. Existing studies of this phenomenon ha...
Article
In the current context of climate change, high Alpine rock slopes and surface deposits are affected by a series of geomorphological processes whose evolution is partly conditioned by permafrost warming and thawing. This degradation directly impacts infrastructure in high mountain areas (e.g., huts or ropeway transport systems). In this study, we ai...
Article
Life on Earth vitally depends on the availability of water. Human pressure on freshwater resources is increasing, as is human exposure to weather-related extremes (droughts, storms, floods) caused by climate change. Understanding these changes is pivotal for developing mitigation and adaptation strategies. The Global Climate Observing System (GCOS)...
Chapter
The Joux Valley is located in the Jura Mountains at the border between France and Switzerland. It has a cold damp climate and during the last glaciation, it was covered by a large ice cap, whose decay resulted in a particular esker morphology. The geological structure is characterised by simple concentric folds and conformal structural relief. The...
Chapter
The Diablerets Massif is a striking structural landscape, rising over 2000 m above the valley bottom of Les Diablerets. The massif makes it possible to observe the complex folded structure of a tectonic nappe, as well as the sharp topographical contrast between the resistant limestone rock walls and the surrounding softer rocks. The area is still g...
Chapter
The present time is a significant stage in the adjustment of mountain slopes to climate change and specifically atmospheric warming. This review examines the state of understanding of the responses of mid-latitude alpine landscapes to recent cryospheric change and summarizes the variety and complexity of documented landscape responses involving gla...
Conference Paper
Full-text available
Only few chronological constraints on Late Glacial and early Holocene glacier fluctuations in the westernmost Alps have been published. Pre-Little Ice Age (LIA) moraines of two palaeoglaciers in theÉcrins massif were mapped and then assigned to ice-marginal positions to establish a morphostratigraphy. Thirty-nine 10Be cosmic ray exposure (CRE) ages...
Article
On August 14th 2015 a large debris flow initiated by the occurrence of two slope failures at the front of the Lou rock glacier flooded part of the town of Lanslevillard, France. The present study aims to understand the meteorological and geomorphological context that led to these failures. Investigations were conducted by combining meteorological d...

The Ecrins massif, in the French Alps, is very suitable for TCR dating, due to its granitic and gneissic composition. Nevetheles, only very few data are available so far on the Lateglacial glacier retreat, mainly because of the sparcity of well preserved Lateglacial moraine sequences. For the present study, four moraine sequences were dated by mea...
Article
Only a few chronological constraints on Lateglacial and Early Holocene glacier variability in the westernmost Alps have hitherto been obtained. In this paper, moraines of two palaeoglaciers in the southern Ecrins massif were mapped. The chronology of the stabilization of selected moraines was established through the use of 10 Be cosmic ray exposure...
Article
Full-text available
The past four decades have seen extensive development of the winter sport industry in the French Alps and several hundred ropeway transport systems have been installed in areas where mountain permafrost may be present. Due to current climatic change and the ensuing permafrost degradation, the vulnerability of these infrastructures to destabilizatio...
Article
Full-text available
In the Val Thorens ski resort (Savoie, France), more than 79 infrastructure elements related to ropeway transport systems are located on permafrost. During the last decade, three of them (two top stations and a pylon located around 3,000 m a.s.l.) experienced destabilization which required important adjustment and stabilization work. This study inv...
Article
Full-text available
Permafrost warming has the potential to amplify global climate change, because when frozen sediments thaw it unlocks soil organic carbon. Yet to date, no globally consistent assessment of permafrost temperature change has been compiled. Here we use a global data set of permafrost temperature time series from the Global Terrestrial Network for Perma...
Article
Full-text available
In this study, we propose a methodology to estimate the spatial distribution of destabilizing rock glaciers, with a focus on the French Alps. We mapped geomorphological features that can be typically found in cases of rock glacier destabilization (e.g. crevasses and scarps) using orthoimages taken from 2000 to 2013. A destabilization rating was ass...

Article
Full-text available
Understanding wet avalanche intensity and the role of past environmental changes on wet avalanche occurrence is a main concern especially in the context of a warming climate and accelerated environmental mutations. Avalanches are closely related to fast cryosphere changes and may cause major threats to human society. Here, we used the sedimentary a...
Conference Paper
Full-text available
The monitoring of surface flow velocities at active rock glaciers has a long tradition in the European Alps with first surveys in the 1920s. Since the 1990s annual to seasonal flow velocity monitoring activities have been substantially expanded and partly institutionalized. In this article, we present and compare annual rock glacier surface flow ve...

Knowing the extent of degrading permafrost is a key issue in the context of emerging risks linked to climate change. In the present study we propose a methodology to estimate the spatial distribution of this phenomenon, focusing on the French Alps. At first, using recent orthoimages (2000 to 2013) covering the study region, we mapped the geomorphol...

Article
In the Mediterranean French Alps, the Bérard rock glacier suddenly collapsed during the summer of 2006; this was a rarely documented event in the world, exceptional for the amount of disturbed material (estimated at 250 000-500 000 m3). Located near the lower limit of permafrost, the Bérard rock glacier collapse might exemplify the possible consequ...

Holocene glaciers have contributed to an abundance of unstable sediments in mountainous environments. In permafrost environments, these sediments can contain ground ice and are subject to rapid geomorphic activity and evolution under condition of a warming climate. To understand the influence of ground ice distribution on this activity since the Li...
