> Abstract: Ambient noise and diffuse signals can be used to  
> construct the
> seismic Earth response between two stations. We discuss the  
> fundamental
> properties of wave fields which justify this approach. We present
> examples of applications to the imaging of the crust in California and
> in the Alps. We demonstrate that this technique can be useful to  
> monitor
> weak changes in physical properties in the Earth. We show an  
> application
> to an active volcano.

> Note: Dr. Campillo’s fields of interest are in general seismology,  
> waves
> in complex media: scattering and attenuation; earthquake source  
> imaging.
> He will be available for discussion after the meeting.  Anyone wishing
> to have a discussion with him is asked to contact Michael Longuet-
> Higgins, tel: 858-534-3936 or <mlonguet at ucsd.edu>
