Comparison and integration of active and passive 3D surface wave measures around the Scrovegni Chapel

We performed surface-wave analysis of passive and active dense 3D data, acquired around the Scrovegni Chapel (Italy) for archaeological prospection. First, virtual source cross-correlation gathers were retrieved from ambient noise records. Active gathers and virtual source gathers were then processed separately, but using the same processing scheme, including travel time extraction and surface-wave tomography. Phase velocity maps obtained from passive and active data were compared for the same frequency. A strategy for future joint (active and passive) analysis is finally suggested.
