DEFORMAZIONI SIN E POST SOVRASCORRIMENTI NEI MONTI DEL'UCCELLINA (TOSCANA MERIDIONALE)

A. CAMPETTI, R. CAROSI, F.A. DECANDIA, P. ELTER, A. LAZZAROTTO, C. MONTOMOLI, P.C. PERTUSATI & B. POLVEROSI
The fondamenta! setting of the Monti dell'Uccellina area is made up by the superposition of some tectonic units be­longing to the original internal margin of the italo-dinaric plate, overthrusted by some more internal units (Canetolo Unit). A poliphase tectonic history, characterized by two main tectonic events has been pointed out by geologica! and struc­tural studies. While D 1 phase is responsible of the main over­thrusting of tectonic units and of their successive rethrusting with a...

GEOLOGIA DEI MONTI SIBILLINI NORD-ORIENTALI

M. CHIOCCHINI, G. DEIANA, A. MICARELLI, A. MORETTI & U. PIERUCCINI
In this paper the authors illustrate the geology of the north-eastern part of the Sibillini Mountains (Ap­pennino umbro-marchigiano), on the basis of a geologi­ca! survey (in the scale 1:25.000) extending from the upperValleyof the Fiastrone River (to the North) to the Tenna Valley (to the South). The outcropping units are those typical of the um­bro-marchigiana facies. Some of them, however (calcari a Posidonia, calcari diasprini umbro-marchiginai, scaglia rosata, schlier) present special peculiarities in their litho­logy...

MOVEMENT MEASUREMENTS OF LANDSLIDES TRIGGERED BY ACTIVE FAULTS IN THE WESTERN CARPATHIANS

L. PETRO, J. VLCKO, E. POLASCINOVA & B. KOSTAK
In this paper we describe the monitoring of movements of landslides located along an active faults in the Western Carpathians (Slovakia). The monitoring on selected sites has been covered by national projects of the Ministry of the Environment since 1980, partially from the Ministry of Education (VEGA grant project No. 1/9159/02) since 2002, as well as by COST Action 625 since 2000. Two types of devices were applied for movement measurements: the TM-71 mechanical-optical extensometer...

EVOLUZIONE TETTONICO-SEDIMENTARIA E STRUTTURAZIONE DEL SETTORE DI PIATTAFORMA CARBONATICA LAZIALE-ABRUZZESE NELL'ALTA VALLE DEL F. VELINO

F. CAPOTORTI, F. FUMANTI & G. MARIOTTI
The north-western corner of the Latium-Abruzzi car­bonate platform, facing North and West respectively the Gran Sasso and the Sabina transitional to basin areas, has been studied by stratigraphic and structural points of view. Geological evolution of the area, from upper Triassic to late Pliocene, has been drawn, taking in mind to explain the various influences of tectonics and eustacy on sedimen­tation. We suggest that (trans-)tensive tectonics caused the sinking of sectors of the investigated area...

F. BORRACCINI, M. DE DONATIS, D. DI BUCCI, S. MAZZOLI, A. MEGNA, O. NESCI, S. SANTINI, D. SAVELLI & M. TRAMONTANA
The Quatemary tectonics of the northem Marche sector of the outer Northem Apennines has been analysed. Orogenic struc­tures within the study area include late Miocene - Pliocene, main­ly NE verging thrusts and associated folds whose geometry is locally controlled by gliding on oblique and lateral ramp segments. Post-orogenic features consist mainl y of normal and oblique-slip faults resulting from WSW-ENE oriented extension. [...]

CARTA GEOMORFOLOGICA DELL'AREA COMPRESA TRA S. GINESIO E COLMURANO (MARCHE CENTRO-MERIDIONALE)

&
This brief report constitutes the explanation of a detailed geomorphological map (aimed to applicative purposes) of a hilly area of the Marches (Centrai ltaly). This area is mo­deled on the arenaceous-pelitic and pelitic-arenaceous layers (alternating to each other) of the Laga Formation, those lat­ter are characterized by sub-horizontal or modestely wavvy dispositions. In the paper the main features of the area are sketched and main geological and geomorphological characteristics are described; particular care was devoted...

INTRODUZIONE

U. CRESCENTI
On Monday, 13 th December 1982, at 10,40 p.m. a land­slide occurred on the western suburbs of the city of Ancona (centrai Italy), involving about 2,2 Km' of land along the Adriatic Sea coast, particularly the suburbs of Posatora, Palombella and Borghetto. The disaster damaged 280 buildings, most of them multiple-occupance blocks so that the tota! number of homes affectes was 865. Other types of building was damaged or destroyed: the Faculty of Medicine of...

UN NUOVO CRITERIO DI VALUTAZIONE DEL RISCHIO SISMICO A NEW APPROACH FOR SEISMIC HAZARD EVALUATION

F. IETTO, S. VIOLA & A. IETTO
In this work we present and discuss a new approach for Seismic Hazard. Evaluation which is based on the assessment of four parameters that characterize the geologica! behaviour of the sites and the vulnerability of the urban Systems. These parameters may be derived from: 1) Evaluation of seismogenetic faults (tectonic hazard); 2) Estimates of the potential for the liquefaction of granular non-cohesive sediments; 3) The assessment of landslide risk; 4) The vulnerability of the built-up...

IL MARGINE ORIENTALE BACINO PLIO-PLEISTOCENICO DI LUCCA-MONTECARLO-VINCI: EVOLUZIONE STRATIGRAFICA E TETTONICA

F. CAREDIO, D. ESU & G. TESTA
The Plio-Pleistocene Lucca - Montecarlo - Vinci basin is located in northern Tuscany between the northern Apen­nine (north) and the Arno river (south), and between the Monti Pisani (west) and Monte Albano (east), a NW-SE trending ridge separating the studied area from the Firenze - Prato Pistoia basin (Fig. 1). Detail geological mapping and strati­graphic and paleontologie analyses recently conducted in the eastern part of the basin provided useful data to the under­standing of the...

GEOMORFOLOGIA DEL COMPLESSO CARSICO GROTTA DEL MEZZOGIORNO (4MA-NA) -FRASASSI (1MA-AN) CON RIFERIMENTO AI MOTIVI NEOTETTONICI DELL'ANTICLINALE DI MONTE VALMONTAGNANA (APPENNINO MARCHIGIANO)

M. COLTORTI & S. GALDENZI
The caves under examination develop from m 100 to 260 above the talweg of Sentina stream that conditioned their genesis. The first tunnels are placed on a EW fracture of jurassic age re­established during the Early and Middle Pleistocene uplifting. They seem to testify subterraneous loss of water from a Paleao Sentina to a Paleo Esino river. Somewhat later the activation of a thick series of fractures and faults displaced this former net of galleries...

PROFILO GEOLOGICO TRA L'ARGENTARIO E M.TE CETONA (TOSCANA MERIDIONALE)

R. GELMINI
In the area between Monte Argentario and Monte Cetona the Apenninic belt was interested by a strong compressive phase, Miocenic in age, which developed overthtrusts in both the Paleozoic basement and its sedimentary cover. [...]

QUATERNARY TECTONICS IN THE EPICENTRAL AREA OF THE 1688 SANNIO EARTHQUAKE (BENEVENTO, ITALY): PRELIMINARY RESULTS

B. MASSA, D. DI BUCCI, S. MAZZOLI & A. ZUPPETTA
We present here a first part of a research on the active tectonics of the Sannio area, showing the results of geomorphological and mesostructural analyses carried out on Middle-Upper Pleistocene deposits of the Calore River valley (Southem Apennines). These results are then compared with a reinterpretation of seismological data available in the ]iterature for two seismic sequences, occurred in 1990 and 1997. [...]

RICERCHE GEOLOGICHE SUL GRAN SASSO D'ITALIA (ABRUZZO). V. EVOLUZIONE TETTONICO-SEDIMENTARIA DAL TRIAS SUPERIORE AL CRETACEO INFERIORE DELL'AREA COMPRESA TRA M- CAMICIA ED OFENA (F. 140 TERAMO)

The results of a stratigraphic-sedimentologic study concerning the Upper Triassic-Lower Cretaceous time interval in the eastern section of the Gran Sasso d'Italia area, are described. This in­vestigation, as well as previous ones carri ed aut by the Authors, provides a description of the sedimentary-tectonic evolution during Upper Triassic-Lower Cretaceous of most of the Gran Sasso d'Italia area. The first important event is the fragmentation of the carbonate "paleopiattaforma" by a tectonic exstensional phase occurred at...

VERIFICA DELLE COMPATIBILITA' GEOMETRICHE E CINEMATICHE DEL THRUST-BELT SABINO (APPENNINO CENTRALE)

S. CORRADO, D. COSENTINO, M. PAROTTO & P. VECCHIA
Two balanced cross sections across the E-verging com­pressive structures of the umbro-sabino sector of the Cen­trai Apennines thrust belt are presented in this paper, in order to provide a further geometrie and kinematic constraint to the Neogene evolution of the chain building. In detail, rela­tionships between variations of compressive structural styles and orogenic shortening along the b-axis are investigated in function of mechanical stratigraphy changings. [...]
