A: Map of historical (triangles) and instrumental seismicity (rounds), with their respective intensity and magnitudes. Grey round points correspond to historical seismicity sourced from the FCAT-17 (Manchuel et al., 2018) catalogue integrating the SisFrance earthquakes database [SisFrance, BRGM, EDF, IRSN (2023)], while other round points represent data from Instrumental Seismicity Catalogue covers from the Si-Hex project (Cara et al., 2015). B: Depth and focal mechanisms of the seism. Depth of seismicity is from SisFrance earthquakes database (https://www.sisfrance.net/), and the selected focal mechanism sourced from Mazzotti et al. (2021). Traces of potentially active faults were obtained through the BDFA Database (IRSN).
