FReDNet: a Continuous GPS Geodetic Network
Monitoring Crustal Deformation in NE Italy
Main goals:
•
•
•
•
to determine the distribution of deformation;
to estimate interseismic strain accumulation
on active faults;
to monitor hazardous faults;
geodetic data management and processing.
Centro Ricerche Sismologiche (CRS) of the Istituto Nazionale
di Oceanografia e di Geofisica Sperimentale – OGS
in collaboration with:
UC Berkeley Seismological Laboratory.
