“…5b). This feature is ascribed to the progressive motion of the Adria microplate and its anticlockwise rotation with respect to the Eurasian plate (Anderson and Jackson, 1987;Bressan et al, 1998Bressan et al, , 2003Mantovani et al, 1996). The area is characterized by a compressional stress regime, derived from focal mechanisms (Bressan et al, 2003;Perniola et al, 2004;Slejko et al, 1999;Viganò et al, 2008) and by overthrusts with a southward movement towards the Adria plate.…”

We have studied the stress pattern of Italy using a dataset with 590 data records from the World Stress Map database release 2008 and 106 new data records to test the hypothesis the mean orientation of maximum horizontal stress is different at different depth sections. For this, we split the dataset into a shallow (0-6 km) and a deep (6-40 km) depth section. For the data analysis we used a new statistical tool that calculates the mean orientation on a 0.2° grid. The tool takes into account the distance to each grid point, number and quality of the data records within the search radius, and the radial distribution. The result is a smoothed Italian stress map that displays both; the mean orientation and the wave-length of the stress pattern. The stress pattern does not vary in depth except for two areas (Sardinia and southern Apulia). Therefore stress data from different depths can be used to estimate the mean orientation and the wave-length of the stress pattern in Italy. Furthermore, the smoothed Italian stress map reveals that most of Italy has short wave-length stress patterns (<150 km). This indicates that the stress field is not controlled by first-order stress sources of plate tectonics, i.e. the convergence of Africa with respect to Eurasia, but that second-order stress sources such as topography, density, strength contrasts, and major faults systems are of great importance. In four regions (western part of the Alps, northern Tuscany, northern Adriatic Sea, Calabria and eastern part of Sicily) the wave-length is <100 km. High values of the circular variance of the mean orientation observed here are driven by third-order local stress sources, such as basins or local neotectonic structures.

“…The geochemical affinity of these rocks and the occurrence of deep seismicity (up to 550 km; Milano et al 1994) below the Southern Tyrrhenian Sea led many authors to interpret the Aeolian Islands as a volcanic arc related to the active subduction beneath the Calabrian Arc (e.g. Barberi et al 1973;Beccaluva et al 1985;Ferrari and Manetti 1993;Mantovani et al 1996). However, some authors suggest that subduction ceased about 1 Ma, since when a general uplift coupled with extensional tectonics has affected both the Calabrian Arc and the Aeolian Fig.…”

Volcanic geomorphology and tectonics of the Aeolian archipelago (Southern Italy) based on integrated DEM data

The geomorphological and morphometric analysis of the sea floor topography surrounding the Aeolian Islands, South Tyrrhenian Sea, Italy, provides insights into the relationships between the volcanological evolution of the islands and their tectonic features. We constructed geomorphological maps of the submarine portions of the seven large edifices constituting the islands on the basis of a DEM with a 5 m resolution step. These maps include constructional and destructional landforms such as submarine volcanic vents located west of Lipari and north of Alicudi, and hummocky surfaces recognised north of Lipari and Salina. The latter landforms, together with the occurrence of large scars affecting the main edifices on land, suggest that sector collapses affected some islands. Geomorphological data indicate that the location of subaerial and submarine vents is strongly controlled by local tectonic structures striking WNW-ESE (Alicudi-Filicudi sector), NNW-SSE (Salina-Lipari-Vulcano sector) and NE-SW (Panarea-Stromboli sector). The islands can be divided Editorial responsibility: C. Kilburn into two groups on the basis of some morphometric parameters: a first group with a pancake-like shape, Dp/D (abrasion platform diameter/basal diameter) higher than 0.40 and H/D (total height/basal diameter) lower than 0.13, and a second group with a conical shape, characterised by Dp/D lower than 0.34 and H/D higher than 0.14. These ratios and other morphometric parameters reflect the different volcanological and structural evolution of the Aeolian Islands. The pancake-like shaped complexes have been created, in addition to their submarine stage, by extrusive and highly explosive activity, whereas the cone-shaped edifices have been characterised by effusive or moderate explosive activity.

“…The plus signs correspond to Larderello-Travale and Mt Amiata geothermal areas, where heat flow reaches 1,000 and 600 mW/m 2 respectively (from Baldi et al 1995, modified). The traces of the CROP18 and CROP03 (partially) crustal seismic reflection profiles are also given region (Mantovani et al 1995(Mantovani et al , 1997a(Mantovani et al , b, 2002Gueguen et al 1998;Doglioni et al 1998Doglioni et al , 1999aMauffret et al 1999;Zech, 1999). So far, very few review papers have been published in recent years in order to discuss this new idea.…”
