| Résumé : |
|
We have devised a laboratory experiment to investigate the frictional and acoustic patterns of a salt slider with cumulated slip. We record a continuous change of the frictional behavior of the slider from stick-slip to the stable sliding regime, similar to the transition from earthquake to slow slip event along subduction zone. The Acoustic Emission associated with the movements of the slider evolves with cumulative displacement and interface ageing. It follows a trend from strong impulsive events, similar to earthquake seismic signals, to a collection of smaller amplitude and longer duration signals, similar to NVT. Our results favor the hypothesis of a common origin to SSE and NVT, which would be found in the slip with friction of a deformable interface. |
