In this study, multi-frequency Synthetic Aperture Radar Interferometry (InSAR) data are used to constrain the ground deformation due to the August 21st, 2017, Ischia earthquake. InSAR results are the input data to infer the source model of the seismic event. C-band Sentinel-1 and Xband COSMO-SkyMed© InSAR results show a displacement pattern in the epicentral area, with a maximum value of ~3.5 cm with a dominant vertical component. Preliminary analytical and numerical models suggest that the retrieved InSAR ground displacements are due to the combination of two different phenomena: the tectonic dislocation caused by the slip on the fault plane and the surficial displacements caused by the dynamic triggering of shallow landslides.

Abstract
In this study, multi-frequency Synthetic Aperture Radar Interferometry (InSAR) data are used to constrain the ground deformation due to the August 21st, 2017, Ischia earthquake. InSAR results are the input data to infer the source model of the seismic event. C-band Sentinel-1 and Xband COSMO-SkyMed© InSAR results show a displacement pattern in the epicentral area, with a maximum value of ~3.5 cm with a dominant vertical component. Preliminary analytical and numerical models suggest that the retrieved InSAR ground displacements are due to the combination of two different phenomena: the tectonic dislocation caused by the slip on the fault plane and the surficial displacements caused by the dynamic triggering of shallow landslides.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
