The five most significant earthquakes from 2010 to 2019. (a) Map at national scale of the epicenters of the five most significant earthquakes (red stars), compared with location of the Mw ≥ 3 historical (yellow) and instrumental (orange) seismicity from FCAT-17 catalog (Manchuel et al., 2018). This catalog covers the period 463 to 2009 merging the SisFrance historical macroseismic database (Scotti et al., 2004) converted in Mw with calibrated intensity prediction equations (Baumont et al., 2018; Traversa et al., 2018), and the SiHex instrumental catalog (Cara et al., 2015). The major faults are represented in black lines (Chantraine et al., 1996). In subplots (b–f), focal mechanisms associated to the five most significant earthquakes are obtained either by polarity inversion of the first arrivals (red) or by full-waveform inversion (blue). The major faults (bold) and minor faults (thin) are represented with grey lines. (b) The ML 5.1 Lys-Haut-Layon earthquake on June 21, 2019. (c) The ML 5.1 La Rochelle earthquake on April 28, 2016. (d) The ML 4.9 Montendre earthquake on March 20, 2019. (e) The ML 5.4 Le Teil earthquake on November 11, 2019. Green star is the 1909 Lambesc earthquake. FMD is the Moyenne Durance Fault zone. (f) The ML 5.1 Barcelonnette earthquake on April 7, 2014. The red dashed line symbolizes the French-Italian border.
