Riassunto analitico
The recent seismic events of Garfagnana (January 2013) and Lunigiana (June 2013) drew the attention of geological community on the seismotectonic problems regarding the internal segment of the northern Appenines and its seismic sources. Recent geological evolution of northern Apennines, as well as longer term ones, are characterized by contractional tenctonic activity in the foreland accompanied by extensional structures in internal domain (Elter et al., 1975; Meletti et al., 2000). This kynematic setting is still active today as documented by crustal deformation data given by GPS analysis (Bennett et al., 2012) and seismological data (INGV). Recent and active back-arc extensional tectonic of northern Appenines lead to the evolution of extensional basins in northern Tuscany and eastern Liguria; those basins bound the eastern, northern and western sides of the Alpi Apuane structural hight.
This work, based on a revision of geological, geomorphological, geodetic and seismological (instrumental and historical) data, will discuss some problems related to recent and active tectonic of the internal Apennines to the North of the Arno river with a particular attention to the fault system, related whit the 2013’ seismic events. Furthermore the multidisciplinary cross analysis allowed defining in a temporal term, also considering the actual tectonic regime (Muir Wood & Mallard, 1992; Tondi, 2000; Galadini et al., 2012), the activity of the main faults to the scale of the Northern Apennines internal domain. The structural and architectural characteristics, as well as the kynematics and the strain rate of the represented fault systems were however subject to documentation attempts.
