GNGTS 2019 - Atti del 38° Convegno Nazionale

16 GNGTS 2019 S essione 1.1 fringe the Adriatic foreland has been suggested for the Northern Apennines, facing the Po Plain foreland (Castellarin et al. , 1985; Masetti et al. , 2012; Livati et al. , 2018) and the Albanides, facing the Southern Adriatic foreland (Argnani, 2013). The Mesozoic paleogeography of the central-northern Adriatic is still less well defined and the structural trends, in particular, are poorly constrained. It will be explored whether the hints offered by the mid-lower crustal earthquakes of the Adriatic domain can help contraining the large-scale Mesozoic structural trends. Furthermore, an interference between seismicity related to the Apennine fold-and-thrust belt and the deeper foreland seismicity can be hypothesized. Acknowledgements. The data concerning location, hypocentral depth, magnitude, and focal mechanism of the earthquakes mentioned in the text are taken from the INGV website http://cnt.rm.ingv.it/event/ , unless otherwise indicated.
