Mid-term review results of the ESA STSE Pathfinder CHARMING project (Constraining Seismic Hazard Models with InSAR and GPS)

Abstract

We probe the feasibility of integrating GPS and Synthetic Aperture Radar deformation rates within the seismic hazard models of the central Apennines (Italy), exploiting data from over 100 GPS stations and the ~20- year long ERS and ENVISAT SAR image archive. We then use a kinematic finite element model to derive the long-term strain rates, as well as earthquake recurrence relations. In turn these are input to state-of-the-art probabilistic seismic hazard models, the output of which is validated statistically using data from the Italian national accelerometric and macroseismic intensity databases.Published23-273T.
