Velocity Changes of Rock Glaciers and Induced Hazards
International audience Recent observations and geodetic measurements in the European Alps show thatchanges are occurring on rock glacier dynamics, ranging from moderate velocityvariations to strong acceleration or even total collapse. These changes can berelated to the ground temperature and to clim...
