Data collection was performed using seismic nodes and six-component seismic stations: five stations Reftek recorders provided by INGV - Sezione Roma 1 (Italy) and six Certimus seismic stations from Cerema, as part of a collaboration between the Istituto Nazionale di Geofisica e Vulcanologia and Cerema.

Five concentric arrays, with radii of 50, 100, 200, 300, and 400 meters, were installed, each consisting of five stations. These arrays were active for a few days, centered around the SAN0 seismic station, which recorded the second shock of the Emilia Romagna seismic sequence in 2012. The Certimus seismic stations, co-located with nodes, were placed at the 400-meter radius and at the center, while INGV stations, also co-located with nodes, were installed on the 200-meter circle. Nodes alone were used for the remaining circles. Additionally, 46 single-station recordings were performed.

The project proposal “SISFelice: Towards the Identification of the Physical Mechanisms Driving Nonlinear Soil Behavior Using Accelerometric Data: Site Characterization of San Felice” (PI: Julie Régnier) aims to study the impact of nonlinear soil behavior on site response during earthquakes. Within the framework of Joya El Hitti’s PhD, our research seeks to differentiate the physical mechanisms behind nonlinear soil behavior for more accurate earthquake predictions based on seismological observations.

In this project, we plan to utilize earthquake recordings from the 2012 Emilia Romagna earthquake sequence at SAN0, San Felice sul Panaro, a site known for liquefaction. Despite nearby geotechnical tests, there remains a gap in characterizing the variability of site response and shear wave velocity profiles. Our project aims to address this by conducting single-station H/V measurements to assess spatial variability in site response and characterize the shear wave velocity profile down to bedrock.
