DESCRIPTION:Michel Campillo\, Professor at Université Joseph Fourier\, "I
 nstitut des Sciences de la Terre" Grenoble\, France\nWe use the ambient no
 ise to image the geological structures and to monitor slight changes in th
 e elastic properties of the crust. This recently developed technique takes
  advantage of the huge quantity of data provided by continuous digital sei
 smic networks. We discuss the principle of the method and show its applica
 tions for imaging at different scales. We present examples of temporal cha
 nges of seismic speeds associated with volcanic eruptions\, earthquakes an
 d transient deformation ('creep') at depth. We discuss the possible origin
 s of these changes.
