[(RECENT RESULTS :

- Body-Wave Imaging of Earth’s Mantle Discontinuities from Ambient Seismic Noise

Slowness-time stacks of the noise correlations (top) and the synthetic seismograms calculated using the AK135 standard Earth model (bottom). Note the wave arrivals at the same times as predicted by the AK135 model (Copyright SCIENCE/AAAS).

- Emergence fo body waves from seismic noise

Comparison of the acausal part of (left) RR cross correlations plotted as function of inter-station distances and (right) radial component earthquake data plotted as function of epicentral distances. All the signals are filtered between 0.5 and 1 Hz. PmP indicates the P waves Moho reflection and Rg the Rayleigh waves. (Poli et al., 2012, GJI )
