A number of seismic methods exist to image the lithosphere below a collection of receivers, using distant earthquakes. In the current practice, especially mode-conversions in teleseismic phases are utilized. Instead, body-wave seismic interferometry can be used. With seismic interferometry, reflections are extracted from the coda of distant seismicity. This allows the creation of reflection responses as if there were large seismic sources at receiver locations. These reflections can be further processed into sharp reflectivity images.

In this presentation, I will explain the basics of body-wave seismic interferometry. And, for a few arrays around the world, I will give examples of field-data applications, ranging from imaging the near surface (few hundred meters) to imaging the entire mantle.
