Title: | GPS observations of coseismic deformation following the 2016, august 24, Mw 6 Amatrice earthquake (Central italy): Data, analysis and preliminary fault model | Journal: | Annals of Geophysics | Series/Report no.: | fast trak 5/59(2016) | Issue Date: | 2016 | DOI: | 10.4401/ag-7269 | Abstract: | We used continuous Global Positioning System (GPS) measurements to infer the fault geometry and the amount of coseismic slip associated to the August 24, 2016 Mw 6 Amatrice earthquake. We realized a three-dimensional coseismic displacement field by combining different geodetic solutions generated by three independent analyses of the raw GPS observations. The coseismic deformation field described in this work aims at representing a “consensus” solution that minimizes the systematic biases potentially present in the individual geodetic solutions. Because of the limited number of stations available we modeled the measured coseismic displacements using a uniform slip model, deriving the geometry and kinematics of the causative fault, finding good agreement between our geodetically derived fault plane and other seismological and geological observations. |
