  author={Agn{\`e}s Helmstetter and Barbara Nicolas and Pierre Comon and Michel Gay},
While basal icequakes associated with glacier motion have been detected under Antarctica for several decades, there remains very little evidence of stick-slip motion for Alpine glaciers. Here we analyzed 2357 basal icequakes that were recorded at Glacier d’Argentière (Mont-Blanc Massif) between February and November of 2012, and that are likely to be associated with basal sliding. These events have been classified into 18 multiplets, based on their waveforms. The strong similarity of the… CONTINUE READING
