The high incidence of soil slips in an area of Calabria (Southern Italy) that is representative of a
typical geo-environmental context, suggested a research aimed to the geotechnical characterisation of finegrained
soils involved in this kind of instability. The paper shows the geotechnical investigation carried out
on samples coming from two test sites individuated in the study area named Stretta di Catanzaro . The results
give a first reference scheme about the physical-mechanical characteristics of the soils affected by shallow
and fast sliding-flow soil slip instabilities. In particular, they permit_ to characterise soils with stress
levels coherent with the thickness of the materials involved in shallow instabilities; to define the influence of
soil saturation on its shear strength; to investigate about the influence of degradation processes on shear
strength.

The recent activity ofthe "Serra di Buda" landslide near the town of Acri suggested to verify and
improve a methodology to characterise rainfalls which could trigger slope instabilities. The landslide, already
active in the past, involves weathered ami/or degraded gneissic and granitic rocks. An historical research allowed
to individuate many dates concerning slope instabilities induced by rainfalls near Acri. The study used different
hydrological analysis techniques to individuate pluviometrical scenarios of landslides with shallow, medium
deep and deep failure surface_ the first ten critic cases were individuated and compared with historical dates for
each hydrological analysis technique using daily rainfalls. The historical research has been completed by the
geomorphological characterisation of the landslides near Acri and repeating the comparisons. This study permits
to individuate the periods in which the historical research could be improved and the values of the parameters
able to characterise pluviometrical instability scenarios.

alabria region does not present relevant homogeneity for what regards the number and the characteristics of the pluviometrical events affecting it. Using about 200 historical series of daily rainfalls, for which at least 15 years of observations are available., an investigation has been carried out to point out the spatial distribution of rainfall events number and magnitudes. The applications relative to this approach, called POT (Peak Over Threshold) or PDS (Partial Duration Series), examine the generic historical series constituting the whole stochastic process. First, the maximum intensity has been assumed as the magnitude of the generic event, then other factors such as total rain and average intensity of the event itself have been assumed too. The analysis has been carried out on events exceeding, in some prefixed threshold, conditions for what regards the above-mentioned factor. Definitively, the events of the past presenting peculiar characteristics over variable threshold values have been calculated and analysed. The description of the spatial variability of the number and magnitude of pluviometrical events exceeding threshold values is proposed through maps traced with the "Kriging" method. The methodology we used permits to delineate the areas of the regional territory affected by major pluviometrical risk for what regards shallow slope instabilities; moreover the periods during the year in which the events, relative to exceeding threshold values, are more frequent have been pointed out.

One of the most frequent landslide triggering causes are rainfalls which can determine such variation in pore pressures to reduce the shear strength and to determine slope instabilities. To realize failure mechanisms, surveys, investigations and analysis are expensive indispensable conditions. Then hydrological models are very useful to define scenarios that could trigger landslides generally classifiable and connected to homogeneous geo-environmental contexts. Three classes of instabilities are considered_ shallow (SH), medium deep (MD) and deep (DD) landslides. The hydrological analysis has been carried out for three areas of Calabria (Italy) referring to geo-environmental contexts in which landslides, referable to the considered classes, are traceable. For SH the employed procedure consists of analysing the heaviest rainy events. The analysis of rainfalls cumulated at the daily scale on prolonged periods or an indirect analysis of the soil moisture content, through the AR(1) autoregressive model, are used to study MD. For the DD, temporal periods longer than one rainy season are considered. A monthly temporal scale is then adopted with reference to cumulated rainfall and to the AR(1) model. Results allow us to define possible triggering scenarios for the considered instability classes and in the ambit of the geo-environmental contexts chosen as references. The scenarios we found may allow us to calibrate the instability mechanisms referring to simplified geotechnical schemes individuated as representative of homogeneous geo-environmental contexts.

Over the last 10 years a number of studies of climate have shown that a number of variables, e.g. the air temperature, the chemical composition of the atmosphere, the rainfall and the mean sea level, have been experiencing important changes. Changes in climate, mainly due to human activities, if confirmed and inferred for the coming decades, may also cause relevant changes in biological, physical and socio-economic systems. This paper reports an investigation into the precipitation and temperature trends in the biggest Calabrian basin. The same data set has been used for the investigation of the evolution with time of the most commonly used aridity indexes. The results indicate a predominantly positive trend for maximum temperatures, as well as negative trends for minimum temperatures and rainfall depths, but no generalizations are made.

The paper deals with stability conditions of a landslide occurred in a town of Calabria, Southern
Italy, during the winter 1998-1999. The slope is constituted by outcropping gneissic and granitic rocks
that are strongly weathered and degraded. In depth the rock mass is characterised by wide zones of completely
degraded rock that are associated to tectonic sub-horizontal structures. The displacements produced by
the last activation caused cracks and strong deformations in the paving of an important national road, moreover
they caused the opening of large and deep fractures in the slope. The trigger cause is not directly correlated
to pluviometric events. Emergency monitoring of displacements allows to delineate some characteristics
of the post failure conditions and to individuate the slope instability s geometrical features. The cognitive outline
includes a geotechnical characterisation and it permits to define a preliminary geotechnical model and to
effectuate a sensitivity analysis of slope stability conditions.

The term soil slip is widely used in world literature to indicate fast landslide that involve soil
covers. Shallow landslides like soil slips happen in almost every Country in the World and affect different
geo-environmental contexts. Generally the extreme danger of soil slip is underlined and related to its extreme
rate and its high distribution density on the affected slopes. Calabria region (Southern Italy) results to be affected
by this kind of instability, they get triggered by particularly intense rainfall events involving almost all
the cropping rocks. This susceptibility, recently well underlined by soil slips triggered during the winter
2002-2003, becomes firmer in various events of the recent past (September 2000, October 1951 and 1953).
For this reason a study has been carried out to define, in an organic way, the geo-environmental characteristics
of some areas affected by soil slips in Calabria.

Multifractal theory was developed by a number of workers in
different fields of scientific research, together making a large contribution to
civilization. More recent developments have concerned hydrology, with
drainage basins and river networks analysed through several hydrological
variables. Generalized fractal dimensions are seldom reconstructed analytically,
as in a few theoretical cases, since in practical applications the numerical
estimation is the only possible way. Many algorithms have been created to
assess the fractal dimensions and the multifractal spectrum in general. Two
main classes can be distinguished_ the Fixed-Size Algorithms (FSA) and the
Fixed-Mass Algorithms (FMA). Different methods are briefly illustrated in
this paper and applications of FSA to natural river networks and hydrological
response are shown.

Negli ultimi anni analisi effettuate sugli andamenti temporali di alcune variabili climatiche hanno messo in risalto l'esistenza di sensibili variazioni globali del clima terrestre. Anche per l'Italia studi condotti da diversi autori, sia sulle precipitazioni sia sulle temperature, hanno confermato significative varia-zioni di dette variabili. In questa memoria si presenta un'analisi effettuata sui dati idrologici misurati in sta-zioni pluviometriche e termometriche ricadenti nel bacino del Fiume Crati (Calabria). Le elaborazioni hanno riguardato le altezze annue di pioggia, le temperature massime e minime estreme per ogni anno di osserva-zione e il numero di giorni piovosi. L'analisi dei trend climatici, svolta utilizzando consolidate tecniche stati-stiche, ha mostrato, per le temperature, una tendenza media all'incremento dello scostamento tra i valori mas-simi e minimi, e, per le precipitazioni, la generale tendenza negativa, sia per le altezze di pioggia annue sia per il numero di giorni piovosi. Se è vero che la tendenza all'estremizzazione delle temperature è da confer-marsi con lo studio di una quantità di dati più significativa, tuttavia il trend negativo delle precipitazioni, già riscontrato in precedenti studi, potrebbe costituire un segnale di modifica non trascurabile delle caratteristiche climatiche della Calabria.

La Calabria presenta accentuata disomogeneità rispetto al numero ed alle caratteristiche degli
eventi pluviometrici cui è soggetta. Utilizzando tutte le serie storiche delle precipitazioni a scala giornaliera
per le quali siano disponibile per il territorio regionale almeno 15 anni di osservazioni, è stata condotta una
indagine volta ad evidenziare la distribuzione spaziale del numero e della magnitudine degli eventi di pioggia.
Le applicazioni relative a questo approccio, denominato POT (peak over threshold) o PDS (partial duration
series), sono state proposte solo di recente ed in numero limitato ed esaminano la generica serie storica
costituente il processo stocastico nel suo complesso. Nello specifico sono stati assunti, quale magnitudine
del generico evento, diversi fattori ed in particolare la pioggia totale, l'intensità massima, l'intensità media e
la durata dell'evento. L'analisi è stata condotta sugli eventi che eccedono prefissate condizioni di soglia relativamente
a qualcuno dei fattori sopra menzionati. In definitiva, vengono conteggiati ed analizzati gli eventi
pluviometrici del passato che presentano una o più caratteristiche di eccezionalità in base al superamento di
valori di soglia variabili. La descrizione della variabilità spaziale del numero e delle magnitudini degli eventi
di pioggia eccedenti i valori di soglia è proposta mediante mappe costruite con il metodo "Kriging".
L'approccio proposto permette inoltre di evidenziare i periodi dell'anno in cui si collocano con maggiore
frequenza gli eventi per prefissati valori dei fattori di magnitudine.
