A long -term field experimental work is at the base of this paper, wich refers of the mechanisms operating in many landsslides as well as of the artificial reproduction in laboratory of the phenomena observed in nature. Sophisticated test procedures allowed defining a base knoledge on the processes governing the landsliding. In other words, the occurrence in an intermittent clay mudslide of different thereshold piezometric values sufficient of making the landslide rapidly moving and the developing of counterbalancing viscous resisting forces capable to drammatically reduce the hight velocity peaks, wich may occur at the very initial movement srage, were ascertained by means of long-term monitoring. In contrast, only one threshold, clearly lower and corresponding to measured residual shear strenght, was identified to stop the movement. This finding induced the authors to delve inside the mechanism governing the phenomenon. Laboratory tests were carried out by means of modified shear apparatuses in order to reproduce as much as possible the in situ shear stress conditions. The results confirmed that a phenomenon of shear strenght regain is operative, both in situ and in laboratory.

On low depths, soils are exposed seasonally to frequent wetting-drying and freezing-thawing cycles; the degradation effects of these cycles are more pronounced in clayey soils. The number of cycles is due to periods of rainfall and variations in air temperature. Such processes can trigger shallow instability essentially controlled by the physical weathering of soils. An experimental study was carried out to investigate how the physical weathering, reproduced by laboratory wetting-drying and freezing-thawing cycles, affects the mechanical behaviour of natural clays in the superficial layers. For this purpose block samples of Pliocene clays were taken from a slope in Southern Calabria (Italy). They are overconsolidated stiff clays which can be classified as to high plasticity clays (CH). Different specimens were trimmed from the block samples and they were subjected to different numbers of wetting-drying-freezing-thawing cycles and then tested in oedometer and direct shear tests. Results of oedometer and direct shear tests seem to show that the physical weathering has caused a degradation of the bonding due to an insufficient ability to resist this cyclic process. The variations of peak shear strength are pronounced in the first month then they may be regarded as essentially constant. The wetting-drying-freezing-thawing cycles also cause a decrease in compression index and an increase of swelling index.

The present study presents an assessment of the erosion for two basins located on the Ionian side of southern Calabria (southern Italy). Two different approaches are considered to evaluate soil erosion_ a qualitative method, based on aerial photo interpretative analysis, and a quantitative method, based on the RUSLE model. The percentage of area affected overall by surface erosion proves to be greater using the quantitative approach (38.5%) compared to the qualitative (13.3%). The mean erosion estimated using RUSLE is about 3.5 mm year

To assess the spatial and time trend of salt contamination due to seawater intrusion for Apulian groundwater, a salinity threshold value dividing fresh groundwater from seawater contaminated groundwater is determined. The trend of 0.5 g/l salinity contour line in the period 1981-2003 is analysed. The salt contamination is also characterised whit respect to 17 time series of monthly chlorine concentration, a parameter which can highlight the seawater contamination effects. Data from 1968 to 2001 are considered and compared with rainfall and temperature time series. The increased saline contamination is closely related to droughty years and to the increasing discharge by wells.

The Apulian region is characterized by very low availability of surface water resources due to the its widespread karstic nature. Considerable groundwater resources are located in large carbonate coastal aquifers. Groundwater for domestic, irrigation and industrial use has been withdrawn in large and increasing quantities over the years, it still allows the development of local population. Groundwater is affected by two types of degradation risks_ quality and quantity degradation. Starting by the analysis of long hydrological time series, the dramatic decreasing trend of groundwater availability is characterised and the negative effect in terms of groundwater quality is highlighted.

The Tremiti Archipelago (Southern Adriatic Sea),
also called Insulae Diomedae from the name of the Greek
hero who first landed there, is an area of high landscape
and historical value. It is severely affected by significant
geomorphologic processes dominated by mass movements
along the coast that constitute the most important and unpredictable
natural hazard for the population and cultural heritage.
Coastal erosion is favoured by the peculiar geological
and structural setting, seismic activity, weathering, development
of karst processes, and wave action.
The present paper reports on descriptive and qualitative
evaluation of the factors controlling landslides and coastline
changes based on medium-term in situ observation, detailed
surface surveys at selected locations since 1995, and historic
and bibliographic data.
The Tremiti Archipelago is part of an active seismic area
characterised by a shear zone separating two segments of the
Adriatic microplate that have shown different behaviour and
roll back rates in the subduction underneath the Apennines
since middle Pleistocene.
Although coastal morphology can be basically considered
to be the result of wave action, the continual action of subaerial
processes contributes effectively to the mechanism of
shoreline degradation. Weathering mainly affects the marly
calcisiltites and calcilutites of the Cretaccio Fm. and the friable
and low cemented calcarenites and biomicrites of the
San Nicola Fm. The cliffs are characterised by different
types of failure such as lateral spreads, secondary topples,
rock falls and slides. At the Isle of San Nicola, landslides are
controlled by the contrast in competence, shear strength and
stiffness between the Pliocene re-crystallised dolomitic calcarenites
and calcisiltites and the Miocene marly calcilutites
and calcisiltites. At the Isles of San Domino and Caprara
rock falls are attributed to the undercutting of waves at the
base of the cliffs.

Remarkably fast socio-economic development over the past few decades stressed the Region of Apulia's hydrogeology by originating different hazard sources. Massive groundwater withdrawal increased and aquifers were also increasingly bound to be a sort of ultimate receptacle for domestic and industrial wastewaters. The entire region underwent twofold human-origin pollution caused by saline seawater and chemical-physical intrusion.
The importance of impaired natural resources and situation severity called for an approach based on all scientific knowledge available, supplemented by up-to-date investigations on groundwater. The main objective was to identify quality trends availability degradation and groundwater resource risks, by using different GS integrated methodologies and developing management tools, the latter to be simple, quick, affordable and as low cost as possible. The proposed approach was based on groundwater vulnerability assessment and use of an automatic hydrogeology monitoring network, the analysis of rainfall, air temperature, river flow yield time series and, more importantly, piezometric level checks to quantify groundwater availability changes, salinity trend analysis to assess changing seawater intrusion effects, groundwater quality schematic mapping with available chemical- physical laboratory data and multi-parameter logging for fast groundwater quality classification. Each tool used is summarised with the main results ofapplications to Apulia's aquifers.

he predisposing factors and the determining factors of seawater intrusion in wide carbonate aquifers of Apulia ( Southern Italy) are characterized. Main predisposing factors prove the sedimentation environment, the tectonic-karstic evolution, the geometry of the aquifers in relation to the coastline, the depth of the aquifers, the existence of underground outflows and their chemical nature. The effect of salinity pollution and its trend was characterized using data from a regional monitoring network, considering logs time series, and also from well loggings. The intensive and widespread use has led to a progressive deterioration in water quality, particularly in the Salento area, right where the aquifer is most susceptible to seawater intrusion.

The town of Agrigento and the surrounding Valley of Temples represents a place of world importance because
of the historical, archaeological and artistic value of their monuments. Since ancient time the town planning expansion of
Agrigento has been controlled by the particular geological set up of the area and the repeated and extensive instability
phenomena The safeguard of this precious cultural heritage is seriously threatened by slope failures including falls, rock
topples and rock slides involving the calcarenitic outcrops. While rotational and translational slides occur when failures
develop in the clay and sandy-silt soils below the calcarenitic levels, involving wide areas. This paper explains the
geological and structural set up, the geotechnical aspects and man-made factors that exert major influence on this
phenomena, on the stability of the area and on the basal foundation of the temples, above all of the Juno Temple.

L'assetto neotettonico del bordo orientale del graben del Crati è
definito da faglie estensionali quaternarie ad andamento N-S, nel
settore meridionale, e WNW-ESE, in quello settentrionale.
Le faglie N-S sono organizzate in una gradinata, ribassante verso
occidente, che consente il sollevamento dell'horst cristallino-metamorfico
silano e culmina con le direttrici «Rogliano-Cèlico-Serra Castellara
» e «Dònnici-San Pietro in Guarano-Luzzi». Le faglie N-S
risultano più «fresche» morfologicamente procedendo da est verso
ovest ed evidenziano, alla mesoscala, una componente di trascorrenza
che evolve da fortemente sinistrorsa a debolmente destrorsa.
Le faglie WNW-ESE, meno fresche morfologicamente, individuano
l'horst (metamorfiti ofiolitifere) di San Lorenzo del Vallo, ed
evidenziano, alla mesoscala, cinematismi dapprima trascorrenti sinistri
e successivamente normali.
Nell'area sono inoltre particolarmente diffuse grandi frane e
deformazioni gravitative profonde - queste ultime maggiormente
concentrate ed estese nella zona di transizione tra i due sistemi di
faglia suddetti, ove ne attenuano l'evidenza morfologica e determinano
sensibili disomogeneità nei dati mesostrutturali.
Il settore più meridionale dell'area risulta particolarmente attivo
sismogenicamente, e per i caratteri della sismicità storica e strumentale,
e per le dislocazioni del suolo ed i recenti «ringiovanimenti»
delle scarpate di faglia osservati. La nostra analisi suggerisce inoltre
che il terremoto del 04.10.1870 è attribuibile alla faglia «Rogliano-
Cèlico-Serra Castellara», mentre quelli del 12.10.1835 e del 12.02.1854
alla faglia «Dònnici-San Pietro in Guarano-Luzzi».
