The velocity vectors, reported in Figure two, converge towards Mt. Epomeo with values ranging with CGNSS velocities (see scatter plot in Figure four). The comparison highlights a very good from a maximum of four.27 mm/yr, inside the SW, to a minimum index of 0.83. in the northern agreement among the two datasets having a correlation of 1.42 mm/yr, Because Ischia portion with the island.

We adopt a two-step apand southern sectors of Ischia. by proach [37] consisting of a non-linear inversion to define the source parameters (north, east, depth, length, width, dip, strike, and homogeneous closuring along the plane) by signifies of a non-linear, least-squares inversion algorithm determined by the Levemberg arquardt strategy. Values of 30 GPa and 0.25 are assumed for the shear modulus and Poisson’s ratio in the half-space, respectively. Because of the complicated geological, hydrothermal, and volcanic structural options of Ischia, the deformation source may be assumed to be a horizontal closuring layer [21,23,25] whose unknown parameters would be the depth, the closuringRemote Sens. 2021, 13,information. In particular, we employed the CGNSS data as well as the leveling information reported in [11]. Levelling campaigns start out from an initial reference point which is assumed to be steady (velocity equal to zero). Nonetheless, the CGNSS stations close towards the leveling reference point measure downwards displacements of about -3 mm/yr. Hence, we calibrated the two datasets, adding towards the leveling data a rigid offset of -3.08 mm/yr. To verify the dataset agreement, we 7 of 12 compared the leveling velocities at measure points close to the CGNSS benchmarks with CGNSS velocities (see scatter plot in Figure 4). The comparison highlights a great agreement amongst the two datasets using a correlation index of 0.83. Because Ischia undergoes localized landslide phenomena primarily step, we defined the.
