Seismic source parameters from InSAR data trough neural networks

Fabio Del Frate Fabrizio Rossi G. Schiavon Salvatore Stramondo

In the recent years InSAR (Synthetic Aperture Radar Interferometry) technique showed its wide potentialities to detect the surface displacement field due to an earthquake. Of great interest and usefulness in this context is the solution of the inverse problem that means to recover the source parameters from the knowledge of InSAR surface displacement field. In this work a novel approach for the solution of such a problem is presented.

Geodetic constraints to the source mechanism of the 2011–2013 unrest at Campi Flegrei (Italy) caldera

Geophysical Research Letters (2015)

Elisa Trasatti Marco Polcari Maurizio Bonafede Salvatore Stramondo

Abstract Campi Flegrei caldera (Italy) was affected by a new unrest phase during 2011–2013. We exploit two COSMO‐SkyMed data sets to map the deformation field, obtaining displacement rates reaching 9 cm/yr in 2012 in the caldera center. The resulting data set is fitted in a geophysical inversion framework using finite element forward models to account for the 3‐D heterogeneous medium. The best fit model is a north dipping mixed‐mode dislocation source lying at ~5 km depth. The driving mechanism is ascribable to magma input into the source of the large 1982–1984 unrest (since similar source characteristics were inferred) that generates initial inflation followed by additional shear slip accompanying the extension of crack tips. The history and the current state of the system indicate that Campi Flegrei is able to erupt again, and the advanced techniques adopted provide useful information for short‐term forecasting.

DInSAR techniques for studying the October 23, 2011, Van earthquake (Turkey), and its relationship with neighboring structures

Christian Bignami Carlo Alberto Brunori Marco Chini Valentina Cannelli C. Kyriakopoulos

In October 2011 a strong earthquake hit the Van province, Eastern Turkey. Few days later (November 9 ^th ) an aftershock occurred few km southward. Finally in November 1976 another mainshock took place north of Van along the Caldiran fault. We have investigated the possible relations between 2011 mainshock and aftershock and the link with the 1976 earthquake. In order to complete the work SAR interferometry has been applied to measure surface displacements, while the fault geometries of the mainshock have been retrieved using a Simulated Annealing approach. Moreover the CFF has been calculated to evaluate the role of 1976 earthquake in promoting the 2011 mainshock and, later on, the role of this latter respect to the aftershock in November 9 ^th , 2011.
