No full textthe 2002 Molise, Italy, earthquake: geological and geomorphological data on the San Giuliano di Puglia area
No full textThe small village of San Giuliano di Puglia sustained the most severe damage from the Molise earthquake sequence of October the 31st, 2002. This study involved detailed geological and geomorphological mapping and is supported by a large set of geotechnical, geophysical and drill-hole data available from existing studies. These data were used to compile a seismic microzonation map of the San Giuliano di Puglia area as part of a study officially commissioned by the Department of Civil Defence

Plio-pleistocene tectonic evolution of the western margin of the S.Arcangelo basin (Southern Apennines)
No full textThe S. Arcangelo basin is located on the easternmost reaches of the Lucania Apennines. This basin, filled by Plio-Pleistocene clastic deposits, is interpreted as a piggy-back belonging to a series of Plio- Quaternary thrust-top basins which formed on the eastern portions of the thrust belt during the latest stages of the orogenic accretion.
A detailed analysis of the geometry and structural features of the western margin of the S. Arcangelo basin, as part of a wider- scale investigation involving the whole basin and its corresponding orogenic front, reveals a clear interaction between tectonics and dep- osition. Deposits of middle-late Pliocene age, exposed along the western margin of the basin (Caliandro unit), are presently tilted to the NE with an average dip of 50°. Variations in the geometry of suc- cessive lithostratigraphic intervals of this unit, point to a major pro- gressive angular unconformity that reflects the uplift and tilting of the basin’s margin. The uplift of this region, constrained in time by the age of the Caliandro unit, is the surface effect of the creation of a buried thrust belt in the Apulian carbonate units. A coeval foreland migration of the frontal allochthonous thrust sheets is documented by well data and indicates that the Apulian units have recorded from Late Pliocene a WSW-ENE shortening in the order of 20-25 km

No full textActive deformation in Southern Italy , Sicily and southern sardinia from GPS velocities of the Peri-Tyrrhenian Geodetic array (PTGA)
No full textCampaign measurement (1995-2000) of Global Positioning Sys- tem (GPS) site velocities in southern Italy, Central Mediterranean area, document differential displacements within the orogens rim- ming the Tyrrhenian Sea. Within the Southern Apennines, GPS velocities define two laterally juxtaposed belts of deformation, with transpression in the east and transtension in the west. In the east, ~8 mm/yr convergence between northern Murge-Gargano block and the International GPS System (IGS) site MATE is partitioned across ~east-west striking right-lateral faults, consistent with seismicity and with the offshore geological record. To the south, in northern Calabria, site velocities relative to MATE indicate transpression at ~5 mm/yr, not recorded by seismicity but consistent with the on-land and offshore geological record. In contrast, site velocities along the Tyrrhenian Sea coast to the west diverge from MATE at 2-3.5 mm/yr, and are consistent with the crustal extension documented by seismic- ity and fault slip studies. The transpressional belt is tracked south- ward across the Ionian Sea by oblique convergence of central Sicily sites (2-6 mm/yr) relative to the IGS site NOTO in the Hyblean block. North-western Sicily sites display clockwise rotation, a pattern reflected in the geological and paleomagnetic record. Ssignificant horizontal motion accompanies rotation in north-western Sicily and is probably accommodated by west-northwest – east-southeast and northeast-southwest-striking right- and left-oblique faults, respec- tively, consistent with a regional ~north-northwest – south-southeast trending shortening axis. The ~east-west striking belt of contractional earthquakes observed offshore northern Sicily is consistent with up to ~10 mm/yr geodetic convergence between Sicily and Sardinia. Southern Sardinia sites exhibits differential velocities relative to the IGS site CAGL, suggesting internal deformation which is not recorded by seismicity and might signal incipient fragmentation of the Sardinia margin in response to relative convergence with Sicily
