Active and Passive 3d Seismic Survey Around the Scrovegni Chapel Using Autonomous Nodes

A dense 3D seismic survey, including both active and passive surface wave measures, has been performed around the Scrovegni Chapel in Padua (Italy), in order to provide a deeper understanding of the archaeological setting of the area. In particular, ambient noise has been characterized both in terms of amplitude and direction of propagation. A cross-correlation analysis of 22 hours of continuous recording allowed to reconstruct the virtual source gathers, which are symmetric and comparable to active gathers despite the directional character of noise, typical of an urban environment. These preliminary results demonstrate the potential of this dataset to bring new insights about the area.
