AB - This work extrapolates the application of coda-waves’ imaging, in order to determine lateral anomalies of attenuation
for surficial targets, and providing experimental elements that justify its use in an economic way with a relatively
good resolution. A numerical procedure for the spatial inversion of the attenuation, inside a small region, has been
established. The numerical effectiveness of the inversion was evaluated carrying out a field experiment, which
detects, based on attenuation contrasts, the presence of a tunnel built in the Colombian Eastern Cordillera. The
experimental work allows the validation of the proposed method, and the acquisition of associated information
about the geotechnical conditions at the experimental site.
