Seismic 3D-tomography with statistical constraints on pillars of the Coliseum, Rome

In this work we present the results obtained on some pillars of the Coliseum in Rome using the statistical technique of 3D-tomographic inversio. This approach makes it possible to insert into inversion process statistical a priori knowledge about the velocity field. The key aspect of the method is tha ability to describe the fo0rm of the field without fixing any deterministic constraints; this is obtained by means of Markov (or Gibbs) statistics, the nproper choice of parameters making it possibleto describe a great variety of different fields, so the resulting method is quite general. Using the algorithm we obtained a great improvment in resolution compared to traditiona methods without introducing any artefatcs into the reconstruction, as we will show from the results obtainedon some pillars of the Co0liseum
