“…Although it is generally agreed that the earthquake was the result of normal faulting in the Messina Straits, there are uncertainties over the specific location and throw of the causative fault. Several models of seismic source have been proposed (Schick, 1977;Valensise and Pantosti, 1982;Mulargia and Boschi, 1983;Bottari et al, 1986;Capuano et al, 1988;De Natale and Pingue, 1991;Amoruso et al, 2002), but to date, none of them has been able to fully explain the tsunami observations associated with the event (Pino et al, 2009). Some uncertainties affect also the origin and reconstruction of the 1908 tsunami; its source area was reconstructed by Billi et al (2008) using runup information and the delay between the earthquake and tsunami arrivals along the Calabrian and Sicilian coasts (Omori, 1909;Platania, 1909;Baratta, 1910).…”

“…The CA subduction complex, in fact, is part of the most active seismic belt of the central Mediterranean region; it faces the highly populated regions of southern Italy, which were struck repeatedly by large magnitude earthquakes in the recent past (Bottari et al, 1989;Jacques et al, 2001;Galli and Bosi, 2003;Gutscher et al, 2006;Jenny et al, 2006), often associated with destructive tsunamis (Piatanesi and Tinti, 1998;Tinti et al, 2004). For several major earthquakes in the region, like the 1908 (Mulargia and Boschi, 1983;Bottari et al, 1986;Capuano et al, 1988;De Natale and Pingue, 1991;Amoruso et al, 2002;Pino et al, 2009) and 1693 (Bianca et al, 1999;Sirovich and Pettenati, 1999;Monaco and Tortorici, 2000;Gutscher et al, 2006), it has Polonia et al (2011).

Abstract. The Calabrian Arc (CA) subduction complex is located at the toe of the Eurasian Plate in the Ionian Sea, where sediments resting on the lower plate have been scraped off and piled up in the accretionary wedge due to the African/Eurasian plate convergence and back arc extension. The CA has been struck repeatedly by destructive historical earthquakes, but knowledge of active faults and source parameters is relatively poor, particularly for seismogenic structures extending offshore. We analysed the fine structure of major tectonic features likely to have been sources of past earthquakes: (i) the NNW-SSE trending Malta STEP (Slab Transfer Edge Propagator) fault system, representing a lateral tear of the subduction system; (ii) the out-of-sequence thrusts (splay faults) at the rear of the salt-bearing Messinian accretionary wedge; and (iii) the Messina Straits fault system, part of the wide deformation zone separating the western and eastern lobes of the accretionary wedge.Our findings have implications for seismic hazard in southern Italy, as we compile an inventory of first order active faults that may have produced past seismic events such as the 1908, 1693 and 1169 earthquakes. These faults are likely to be source regions for future large magnitude events as they are long, deep and bound sectors of the margin characterized by different deformation and coupling rates on the plate interface.

“…A verification of reliability of such a modelling for the analytical determination of the epicenter and principal attenuation directions (TERAMO et al, 1995a;1996) can easily be carried out, through a comparison of results which is obtained from specific calculations of those taken from literature (BARATTA, 1909(BARATTA, , 1910BOSCHI et al, 1999;BOTTARI et al, 1979BOTTARI et al, ,1986CAMASSI and STUCCI 1997;SCHICK, 1977). In particular, it has been verified that both the epicenter and the attenuation directions are not Figure 1 Messina earthquake on 28-12-1908: 2nd -level filtered macroseismic plane.…”

A procedure is proposed for the reconfiguration of the macroseismic planes relative to earthquakes that, being characterized by a reduced number of points of observed intensity due to a lack of information, or having the epicenter very close to the coastline, are characterized by an incomplete distribution of observed intensity levels. The design of a plurality of virtual areas, through which a distribution of intensity consistent with an anisotropic model of attenuation is depicted, allows a reliable determination of macroseismic parameters of the same seismic event.

“…The application of the proposed methodology entails, preliminary, the construction of the macroseismic planes of the analysed events and the subsequent characterisation, for each of them, of the minimum and maximum plane systems (Bottari et al, 1986): comparison between the epicentre deduced as baricentre of the maximum intensity area and as centre of the plane vectors system E~ for two modellings of macroseismic field and plane; comparison between the attenuation directions deduced using the modellings of macroseismic field and plane. E~ = {Gi, vi) of vi vectors applied in the Gi baricentre of the homonymous areolas (Figure 4a) or of the single isoseismal area (Figure 4b).…”

A vectorial modelling of observed macroseismic intensity aimed at the analytical determination of the epicentre is proposed here. The methodology is based on the determination of a plane system of vectors which characterises the macroseismic intensity distribution. The epicentre of each seismic event considered is determined as the centre of this vector system by an analytical expression which is independent from all possible directions of seismic energy propagation. The analysis of the intensity distribution is carried out by a new model called a macroseismic plane, different from the one known as macroseismic field, formed by a set of small areas built around the observed intensity points; hence its name.With the proposed methodology, some earthquakes in southern Italy and eastern Sicily are analysed calculating their epicentres, also for distributions of observed intensity which are particularly complex.
