Finite source from geodetic data
The rupture distribution along the seismic source is derived from the analysis of displacement maps (InSAR) obtained through the processing of Sentinel-1, European Space Agency, radar images. InSAR data produced by the INGV GeoSAR Lab with sarscape (sarmap).

Focal Plane FP1

This source model, composed by 3 segments and derived from 2 InSAR dataset(s) all including less than a day after the event, is characterized by a predominantly ESE-WNW oriented source (strike 287°), dipping towards the NNE at 40° degrees and a mainly inverse rupture with a right-lateral component (rake 121°). Slip peak is approximately 2.4 m at a depth of 2.7 km. The energy released by all segments is 6.51e+18 Nm, corresponding to an M 6.5 earthquake. InSAR data, model and ancillary information can be found in the data_and_model.zip file, available for download. Data and models are also affected by an M 6.2 event occurred in the same area 31 minutes before (6:41 UTC)
Expected surface displacement scenario
This section shows maps of the predicted surface displacement based on a finite fault derived from focal mechanisms. Images contain maps of simulated displacement; they only provide qualitative indications about the expected displacement. Use the pull-down menu to select a scenario from those available. Finite fault dimensions and mean slip are based on the scaling factore in Leonard (2010), doi 10.1785/0120090189. Scenarios are available only for a limited period after the event
