“…The kinematic pattern inferred from geological evidence has been clearly confirmed by the results of space geodetic observations, which are described in other papers [31] [53]. The kinematic pattern resulting from such data (Figure 4) indicates that the outer sector of the Apennine chain moves considerably faster (4 -6 mm/y) than the inner Tyrrhenian side of that belt (1 -2 mm/y).…”

It is argued that in some zones of the Northern Apennines, in particular the Rimini-Ancona thrust system, the Romagna Apennines and the Alta Valtiberina trough, the probability of major earthquakes is now higher than in other Apennine zones. This hypothesis is suggested by the comparison of the present short-term kinematics of the Romagna-Marche-Umbria wedge in the Northern Apennines, deduced by the distribution of major shocks in the last tens of years, with the previous repeated behavior of the same wedge, evidenced by the distribution of major earthquakes in the last seven centuries. The seismotectonics of the Apennine region here considered is closely connected with the larger context that involves the progressive migration (from south to north) of seismicity along the peri-Adriatic zones. The information provided by this study can be used to better manage the resources for prevention in Italy.

“…The GPS observations obtained from several continuous operating networks in the study area have been considered in order to recognize the present horizontal kinematic field in the Central and Northern Apennines [10]. In particular, the phase and pseudo-code data of 450 continuous stations operating over the period January 1, 2001-December 31, 2014 have been analysed with the GAMIT software version 10.5 [124] adopting a distributed procedure [125].…”

“…In a number of works [3]- [10], we have discussed the geodynamic context that may generate seismic activity in the axial and outer sectors of the Apennine belt. The proposed interpretation, sketched in Figure 2, provides that such activity is mostly produced by the relative motion among the outer sector of the belt, that stressed by the Adria plate is undergoing lateral escape and uplift, and the inner less mobile zones.…”

Major seismic activity in the Northern Apennines concentrates in few zones, distributed in a peculiar way. It is argued that such context may be plausibly explained as an effect of belt-parallel shortening, which has caused oroclinal bending of the longitudinal ridges formed during the Late Miocene to Lower Pliocene evolutionary phase. The main effects of this process, developed since the upper Pliocene, have mainly affected the outer sectors of the belt. The major seismic sources have generated in the zones where different oroclinal bendings of adjacent ridges have produced extensional/transtensional deformation. In the inner side of the Northern Apennines, belt parallel shortening has occurred at a lower rate. The main effects have resulted from the shortening of the Albano-Chianti-Rapolano-Cetona ridge. In particular, the proposed tectonic setting may account for the moderate seismic activity that occurs in the Firenze, Elsa, Pesa, Siena and Radicofani basins.

“…The relationship between vertical movements and seismicity has been established long ago (Yokoyama and Nazzaro, 2002;Dambara, 1966;Yurkevich, 1964) and is confirmed by modern technologies, in particular, InSAR, (Jung and Hong, 2017;Lu et al, 2003;Cheloni et al, 2017). Based on GNSS measurements at 33 points, significant differences were defined in the coseismic and post-seismic vertical displacement of the earthquake in Italy on April 6, 2009 (Cenni et al, 2012), and the coseismic displacement of the earthquake on August 24, 2016 in central Italy (Cheloni et al ., 2016), consistent with seismic and geological data. Establishing such a correlation can allow the development of a mechanism to forecast generalized seismic activity.…”

Based on experimental studies using the "integral velocity index of the vertical displacement of the territory" and criterion of generalized seismicity, a close functional relationship was found between two parameters of different physical nature: seismic activity and altitude displacements of the Earth's surface in Europe. The mathematical correlation between the generalized parameters of the velocity altitude displacements on the territory and seismic activity is established according to seismic and GNSS stations for the period from 2000-2011 for the areas in Europe with close correlation between seismicity and velocity of vertical movements of the Earth's surface.
