The informatic framework of the database follows that used for the Italian Database of Individual Seismogenic Sources (DISS). In this paper we present the architecture of the new Database of Active faults of the broader Aegean Area relative to Greece, the progress made up to present and the following activities yet to be accomplished.

In order to achieve this goal, we acquired several 1D velocity profiles characterized by an investigation depth of ca. 150 m from the field surface.

An E-W striking fault system, roughly corresponding to the geographic "Soglia Messapica", is also present. This area shows the effects of different phases of coastal evolution. During the Middle Pleistocene, north of the Soglia Messapica, thin coastal deposits accumulated and abrasion surfaces were cut whereas, to the south, marine sediments were deposited. During the last interglacial period, two thin transgressive beach deposits formed along with a dune belt and backdune deposits. From the geodynamic point of view, facies and elevation of marine and coastal deposits suggest that before 125 ka the region north of the Soglia Messapica was uplifting with a higher rate than the southern one. Afterwards, both areas north and south of the Soglia Messapica showed a similar tectonic behaviour, characterised by stability or, locally, by low subsidence rates. Mesostructural analysis on extensional joints indicates that at least three separate deformational events occurred during the Middle and Late Pleistocene. If matched against the uplift rate changes, this structural evolution may be interpreted as due to the shift toward the SE of the peripheral bulge related to the Ionian slab subduction process and to the set up of a different tectonic event in the Late Pleistocene. In the study area such event is essentially characterised by widespread stability, coupled with the development of joint sets which suggest a doming-like deformation mechanism.

Four days later (on October 30^th), the main-shock (<b><i>M</i></b>_w = 6.5) of the whole seismic sequence occurred in the same area. The central Apennines are characterized by northeast-verging thrust-propagation folds, involving Mesozoic- Tertiary sedimentary successions. During the 2016 sequence, coseismic deformation has been recorded at the rear of the Sibillini Thrust which separates the main mountain chain from the Marche-Abruzzi foothills (Fig. 1). This contractional str...

This is mainly due to the complexity of this natural phenomenon in both its genetic aspects and consequential ones.

Both instrumental and historic data are revised and, with few exceptions, this information substantiates that the local seismicity is characterised by a shallow seismogenic depth that can generate important destructions though distributed to limited areas.

These were caused by the liquefaction of a saturated sand layer(s) located at shallow depths (&lt; 15 m). The spatial distribution of these coseismic features follow the limits of the paleo-river beds which are widely present in the Padana Plain. In particular, the villages of Sant&#39;Agostino, San Carlo, Mirabello and Vigarano Mainarda which are situated along the paleo-river bed of the Reno River, were severely affected and considerable damage to both cultural and industrial warehouses occurred while residential buildings suffered less damage. These occupy the western and south western portion of the Province of Ferrara, North Italy (Fig. 1). The observed seismic activities are related to the buried active front of the Romagna and Ferrara thrust belt. In this area, this folded belt represents the advanced northern rim of the Apennines mountains. It is overlain by a thick succession of Pliocene and Quaternary sediments forming a wedge-like shape of sediments underlying the Po Plain. The superficial geology of the test sites is composed mainly of alluvial deposits that has been deposited in different environments comprising: channel and proximal and distal levee, inter-fluvial, meander and swamp (Fig. 1). These sediments form also the main hydrogeological units overlying the bedrock which can be found at depths ranging between several hundreds to few kilometres. This work focuses on the application of geoelectromagnetic methods including: Electrical Resistivity Tomography (ERT), Induce Polarisation (IP) and Ground Penetrating Radar (GPR) techniques. for the characterisation of the subsurface continuity of these ruptures and possibly the geometry of the liquefied sand layer. The geophysical survey was carried out in three sites where ground ruptures are well visible on the ground surface and at the same time being located in the vicinity to residential and industrial building as well as in free field (1, 2 and 3 in Fig. 1).
