It emerges as a doubling of the seismic energy around the source within a spot of width a wavelength, that is several tens of meters in our case. The characteristic time for its onset is the scattering mean free time, that quantifies the internal heterogeneity.4 pagesMesoscale and Nanoscale PhysicsDisordered Systems and Neural Networkstext
