  abstract = {{T}he massive worldwide deglaciation leads to more frequent slope instabilities in mountainous terrains. {T}he physical processes leading to such destabilizations are poorly constrained due to little monitoring of dynamic parameters at the local scale. {H}ere we study a very large slow-moving landslide (similar to 0.8 km(2)), on the flank of {T}ungnakvislarjokull glacier in {I}celand. {B}ased on a combination of remote sensing images, we monitor the landslide and glacier kinematics over 75 years, with a focus over the period 1999-2019 when rapid glacier wastage has been observed. {T}he landslide accelerates from 2 to 45 m/yr in the 6 years following a sudden increase in glacier mass loss. {T}his acceleration coincides with intense quake activity ({M}l < 2.8), recorded by a regional seismic network. {W}e show that this seismicity is caused by the landslide sliding on a rough surface. {T}he evolution of the quake magnitudes suggests a progressive segmentation of the landslide mass during its acceleration.},
