Introduction
Glacier dynamics regulates the advection of ice towards lower elevations with higher temperature and melt rates, and thus controls the supply of fresh water to populations for mountain glaciers (Huss et al., 2014) and to oceans for ice sheets (Ritz et al., 2015). Compared to viscous flow, glacier fracturing, basal sliding and subglacial hydrology are processes that remain poorly known since they remain challenging to (...)

Introduction
The mechanisms at the origin of huge landslides and the external factors modifying their internal dynamics are various and complex, although it is widely acknowledged that earthquakes and rainfall represent the main triggers. Séchilienne is an emblematic rocky landslide which still gathers prickly questions raised for 25 years after administrative, scientific and political managements. This landslide is heavily (...)

Introduction
Freshwater resources and their management will remain an important socio-economic issue of the 21st century. In the context of drinking water production for large cities, there is a need to refine our understanding of the hydrogeological behavior of exploited fields in order to ensure their sustainability and to limit their vulnerabilities to potential pollution. In this context, spatio-temporal monitoring of the (...)

Introduction
Krafla, a quiescent Icelandic volcano whose last eruptive activity occurred in 1975-1984, is now largely exploited for geothermal energy production. In 2009, drilling revealed the presence of a buried shallow (2.1 km) magma body, which was unexpected based on the available geophysical data. This observation gives the unique opportunity to explore the potential and limits of (...)
