GNGTS 2023 - Atti del 41° Convegno Nazionale

Session 1.2 GNGTS 2023 following the 82-84 crisis (panels A,B). Envisat data (2002-2010) detect a few mm/yr of uplift representing the slow inflation phase started in 2003 (panels C,D), whereas the CSK data (2011-2021) highlight the fast inflation phase started in 2011 (panels E,F). The measurements are provided in the original Line-of-Sight (LoS) format, but the combination of ascending and descending data allow to retrieve both vertical (UP) and horizontal (EW) deformation components. Fig.2 shows the UP deformation retrieved in the area of maximum deformation located in Rione Terra, close the San Procolo Martire cathedral. Fig.1: InSAR LoS gound deformation velocity retrieved from: ERS 1-2 ascending (A) and descending (B) acquisitions [1992-2002]; Envisat ascending (C) and descending (D) acquisitions [2003-2010]; CSK ascending (E) and descending (F) acquisitions [2011-2021].
