Geodynamics of the Calabrian Arc, Geodesy, Tectonics, Strain Rate.
Description:
The tectonics and geodynamics of the Calabria region are presented in this study. These
are inferred by precise computation of Global Navigation Satellite Systems (GNSS) permanent
station velocities in a stable Eurasian reference framework. This allowed
computation of the coordinates, variance and covariance matrixes, and horizontal and
vertical velocities of the 36 permanent sites analyzed, together with the strain rates, and
using different techniques. Interesting geodynamic phenomena are presented, including
compressional, and deformational fields in the Tyrrhenian coastal sites of Calabria,
extensional trends of the Ionian coastal sites, and sliding movement of the Crotone Basin.
Conversely, on the northern Tyrrhenian side of the network near the Cilento Park area, the
usual extensional tectonic perpendicular to the Apennine chain is observed. The largescale
pattern of the GNSS height velocities is shown, which is characterized by general
interesting geodynamic vertical effects that appear to be due to geophysical movement and
anthropic activity. Finally, the strain-rate fields computed through three different techniques
are compared.
