We use the ambient noise to image the geological structures and to monitor slight changes in the elastic properties of the crust. This recently developed technique takes advantage of the huge quantity of data provided by continuous digital seismic networks. We discuss the principle of the method and show its applications for imaging at different scales. We present examples of temporal changes of seismic speeds associated with volcanic eruptions, earthquakes and transient deformation ('creep') at depth. We discuss the possible origins of these changes.
