  1. Hypocentral location, moment magnitude and fault plane solution (strike, ϕ, dip, δ and rake, λ, for the principal and auxiliary planes) of the main earthquakes of the Emilia seismic sequence3. For the events marked by an asterisk, locations are taken from the INGV catalog (http://iside.rm.ingv.it) and focal mechanisms are an average of the all 22 known focal mechanisms3. The last two columns list the dominant (ϕD) and secondary (ϕS) rupture directions, respectively, estimated from the PGVs inversion. The uncertainties on ϕD and ϕS have been evaluated measuring the Half Width at Half Maximum of the best-model Pdfs shown in Figure S2.
