Fault Plane solutions in the area
Finite source from geodetic data
Rupture distribution along the seismic source derived from the analysis of displacement maps obtained from Sentinel-1 (Copernicus Project) satellite images. Displacement data produced by INGV GeoSAR Lab with sarscape (sarmap).

Focal Plane FP1

This source model, derived from 5 InSAR dataset(s) including from 4 to 9 days after the event, is characterized by a single NW-SE oriented fault (strike 136°), dipping towards the SW at 43° degrees and a mainly reverse rupture with a right-lateral component (rake 109°). The strike angle has been fixed according to the focal mechanism. Slip peak is approximately 0.4 m at a depth of 7.2 km. The energy released is 4.98E+17 Nm, corresponding to an M 5.8 earthquake. InSAR data, model and ancillary information can be found in the data_and_model.zip file, available for download

Focal Plane FP2

This source model, derived from 5 InSAR dataset(s) including from 4 to 9 days after the event, is characterized by a single SSE-NNW oriented fault (strike 336°), dipping towards the ESE at 37° degrees and a mainly reverse rupture with a right-lateral component (rake 102°). The strike angle has been fixed according to the focal mechanism. Slip peak is approximately 0.5 m at a depth of 7.0 km. The energy released is 5.72E+17 Nm, corresponding to an M 5.8 earthquake.
