DESCRIPTION:Jorge Morales\, CEA Cadarache\, France\nEdge localized modes (
 ELM) are periodic bursts of ejected plasma particles and energy. For ITER 
 the estimations are of several mega Joules of energy per square meter on t
 he plasma facing components. This phenomenon is very harmful and a detail 
 study of its dynamics for a better control/mitigation of this instability 
 is required. To this purpose calculations of the ELM instability have been
  carry out. An analytical expression of the ELM precursors rotation is der
 ived. Also\, nonlinearly\, the saturation of the instability and the eject
 ion of filaments is studied. The described ELM dynamics show to be robust 
 and our results are in qualitative agreement with experimental measurement
 s in several tokamaks (KSTAR\, ASDEX\, MAST and NSTX).
