摘要: Abstract Two small geodetic subnetworks were established in 2010 and 2014, respectively, along the southeastern edge of unstable eastern flank Mt. Etna volcano. These networks have been monitored since late 2014 with GNSS techniques by GEOmatic_laboratory Earth Science Section University Catania. The resulting horizontal velocity field allowed us to observe a westward decay rate different azimuthal pattern motion between two networks. We suggest that both features are due active deformation Nizzeti faults. also observed deforming region is not entirely confined Tremestieri-San Gregorio-Acitrezza fault zones, but it extends southwards. Areal upgrades as well scheduling measurements at least on monthly basis will improve our knowledge current investigated area.
