The deadly earthquakes in Italy (2009, Mw 6.1 L’Aquila; 2016 Mw 6.0 Amatrice and Mw 6.5 Norcia) and the recent seismicity crises in Mayotte, Le Teil and Strasbourg have reminded us that seismicity is a non-negligible natural hazard for our country. Moreover, new technical and theoretical advances have recently challenged the classical understanding of the link between seismicity and crustal deformation in France [Masson et al. 2019; Henrion et al. 2020] and elsewhere [Craig and Calais 2014]. ...
