Preliminary HRGPS Results for the 2016 Amatrice earthquake

The HRGPS results shown in this presentations deal with the first preliminary high-rate time series obtained for the sites of Amatrice and Norcia.

The analysis was performed following Avallone et al., 2012, with PPP strategy (Zumberge et al., 1997) in kinematic mode by using Gipsy-Oasis II software (Bertiger et al., 2010). The kinematic analysis allows to obtain an estimation of the position every epoch of measurement. The analysis was performed by using the available rapid orbits delivered by JPL.

Amtrice shows about 15 cm peak-to-peak ground displacement on the North component and about 10 cm on Vertical one, whereas Norcia show a 15 cm peak-to-peak displacement in the SW direction.
