SeismoCitizen : A project combining seismology and human science approaches based on a deployment of a dense low cost seismic network hosted by citizens.

This poster presents the multidisciplinary project of citizen seismology, called SismoCitoyen, led by Eost, LISEC and SAGE. The project aims to build a real network of observation sites in urban and peri-urban areas, among private volunteers who also participate in a survey conducted by sociologists. Requiring no technical expertise, the equipment installed by Eost makes it possible to increase the mesh size of permanent institutional observation sites and thus improve seismicity detection and characterization, as well as the characterization of the associated seismic risk. They also aim to improve seismological imaging of the subsoil, in particular by passive methods based on seismic noise analysis. This type of experimentation is likely to increase and the modalities for integrating data into the Resif research infrastructure information system are being studied. The seismometer model used allows the host (or his relatives) to consult the recorded data online and in real time. This is where the "social sciences" component of the project comes in, which aims to observe and analyse the effects of citizen involvement in scientific research (via the hosting of a seismometer) on the perception and representations of seismology and micro-seismicity phenomena. LISEC and SAGE are conducting this study via two interviews, one during the installation of the seismometer and the other six to eight months later. The first operational phase of the project took place at the beginning of 2019 with the deployment of 25 stations in the Mulhouse region (Haut-Rhin). The SismoCitoyen project involves the BCSF-RENASS, a national observation service run by Eost, as well as IPGS, LISEC and SAGE. It is financially supported by the CNRS, the University of Strasbourg and the LabEx G-Eau-Thermie profonde.
