This paper shows an investigation on temporal and spatial variability of annual maxima of short duration rainfalls (1, 3, 6, 12 and 24 hours) ranging from 1916 to 2000, selected from the rainfall data set of Calabria (southern Italy). To detect changes in the extreme rainfall series the Mann-Kendall non-parametric test has been used at local scale, considering all the stations involved in the region. Moreover the variability of both parameters and quantiles of empirical intensity-duration-frequency relationships for short duration rainfalls has been explored for different time periods. Finally the monthly distribution of the occurrence process of annual maxima of short duration rainfalls has been statistically analysed.

The following work presents a trend analysis of precipitation observed in Calabria through the Mann-Kendall non-parametric test and a correlation study between rainfalls aggregated at different time scales and two global scale indexes. The results show a general negative trend in precipitation, with the exception of summer season, and links of NAO index with autumn and winter rainfalls, observed in the north-western part of Calabria, and of MO index with winter precipitation, revealing a more uniform distribution throughout the region. Moreover, the NAOI and the MOI, calculated both in autumn and winter periods, have been correlated with precipitation aggregated in enlarged periods, obtaining good correlations for both the indexes with particular reference to the decade 1990-1999. The correlations provide a possible link for water resources
availability when NAOI and MOI are known for the previous periods.

In the past decades, several studies were aimed at defining the relationships between neotectonics and seismicity, and between neotectonics and morphoevolution in Calabria (Southern Italy). More recently, also in cooperation with other colleagues of the CNR-IRPI, our group performed a "combined" analysis of deep-seated morphoevolution, neotectonics and seismicity, and soil-gas radon concentrations in the Crati Graben (Northern Calabria). Similar combined analyses have recently been extended along the NE border of the Sila Massif (again in Northern Calabria), and in the "Stretta di Catanzaro" area (Central Calabria). A more detailed analysis has also been per¬formed in the vicinity of the Acri (CS) village, in the Sila Massif, a study site located on the right flank of the Crati Graben. In the mentioned study areas deep-seated grav¬itational deformations and large-scale landslides, and tectonic structures have been mapped in scale 1/10,000, by means of air-photo interpretation and field examinations. Successively, geological features have been compared with values of soil gas radon concentration, which have been sampled and analysed for the same sectors through geostatistical methods. By cross-analysing the above mentioned geo-environmental items, new insights have been gained into geological hazards related to slope-stability, seismogenesis, and radon emission, and on their mutual relationships. In the present study, the main results of the cited analyses are described, with comparisons of the results obtained in the different study areas. In brief, we found that radon anomalies generally correspond to sectors of severe crustal deformation -i.e. where either neotectonic features or gravitational-tectonic processes, deep-seated gravitational deformations, or large-scale landslides are to be found. Highest radon values match well with active faults, and with macroseismic areas of the main historical earthquakes. On the contrary, large non-diastrophic deformations generally tend to conceal geomorphologic evidence of recent faults, as well as associated Radon anomalies.

Soil slips affect essentially the degraded or weathered covers of soil, and could be particularly
dangerous because of their kinematic mechanism and their spreading over wide areas during rainstorms. The
high incidence of soil slips in an area of Central Calabria (Southern Italy) prompted a research aimed at geotechnical
characterisation of fine-grained soils involved in this kind of instability. This paper illustrates the
geotechnical and the mineralogical characterization carried out on samples coming from three sites representative
of the wider study area, where sedimentary terrain (Plio-Pleistocene) crops out. Classification and direct
shear tests have been conducted on undisturbed specimens and artificially degraded specimens. The results
supply a reference frame of the soils physical-mechanical characteristics. Correlating the geotechnical analysis
with the mineralogical-geochemical investigations allows a wider characterization of the sediment properties.

La modellizzazione spazio-temporale di processi complessi, come quelli idrologici, è di assoluto rilievo in molte scienze ambientali. In particolare, la valutazione della variabilità spaziale e temporale delle precipitazioni riveste estrema importanza soprattutto in aree caratterizzate da una morfologia accentuata. Nel presente lavoro è stato applicato un approccio geostatistico multivariato ad una base di dati costituita dalle medie dei totali annui di precipitazione, calcolate per 8 periodi di 10 anni ciascuno, nei quali sono state suddivise le serie storiche delle precipitazioni registrate in Calabria. L'analisi variografica ha consentito di quantificare la variabilità delle precipitazioni medie annuali dei diversi decenni, evidenziando che circa il 94% della variabilità della media dei totali annui di precipitazione è strutturata. Inoltre, tutta la variabilità tra le medie dei singoli decenni è stata sintetizzata in due indici uno a corto range ed uno a lungo range.

Abstract
A method for mapping lava-flow hazard on the SE flank of Mt. Etna (Sicily, Southern ...
A method for mapping lava-flow hazard on the SE flank of Mt. Etna (Sicily, Southern Italy) by applying the Cellular Automata model SCIARA-fv is described, together with employed techniques of calibration and validation through a parallel Genetic Algorithm. The study area is partly urbanised; it has repeatedly been affected by lava flows from flank eruptions in historical time, and shows evidence of a dominant SSE-trending fracture system. Moreover, a dormant deep-seated gravitational deformation, associated with a larger volcano-tectonic phenomenon, affects the whole south-eastern flank of the volcano. The Etnean 2001 Mt. Calcarazzi lava-flow event has been selected for model calibration, while validation has been performed by considering the 2002 Linguaglossa and the 1991-93 Valle del Bove events -- suitable data for back analysis being available for these recent eruptions. Quantitative evaluation of the simulations, with respect to the real events, has been performed by means of a couple of fitness functions, which consider either the areas affected by the lava flows, or areas and eruption duration. Sensitivity analyses are in progress for thoroughly evaluating the role of parameters, topographic input data, and mesh geometry on model performance; though, preliminary results have already given encouraging responses on model robustness. In order to evaluate lava-flow hazard in the study area, a regular grid of n.340 possible vents, uniformly covering the study area and located at 500 m intervals, has been hypothesised. For each vent, a statisticallysignificant number of simulations has been planned, by adopting combinations of durations, lava volumes, and effusion-rate functions, selected by considering available volcanological data. Performed simulations have been stored in a GIS environment for successive analyses and map elaboration. Probabilities of activation, empirically based on past behaviour of the volcano, can be assigned to each vent of the grid, by considering its elevation, location with respect to the volcanic edifice, and proximity to its main weakness zones. Similarly, different probabilities can be assigned to the simulated event types (combinations of durations and lava volumes, and to the effusion-rate functions considered). In such a way, an implicit assumption is made that the volcanic style will not dramatically change in the near future. Depending on adopted criteria for probability evaluation, different maps of lava-flow hazard can be compiled, by taking into account both the overlapping of the simulated lava flows and their assumed probabilities, and by finally ranking computed values into few relative classes.
The adopted methodology allows to rapidly exploring changes in lava-flow hazard as a function of varying probabilities of occurrence, by simply re-processing the database of the simulations stored in the GIS. For Civil Protection purposes, in case of expected imminent opening of a vent in a given sector of the volcano, reprocessing may help in real-time forecasting the presumable affected areas, and thus in better managing the eruptive crisis. Moreover, further simulations can be added to the GIS data base at any time new different event types were recognised to be of interest. In this paper, three examples of maps of lava-flow hazard for the SEflank of Mt. Etna are presented_ the first has been realised without assigning any probability to the performed simulations, by simply counting the frequencies of lava flows affecting each site; in the second map, information on past eruptions is taken into account, and probabilities are empirically attributed to each simulation based on location of vents and types of eruption; in the third one, a stronger role is ascribed to the main SSE-trending weakness zone, which crosses the study area between Nicolosi and Trecastagni, associated with the right flank of the above-cited deep-seated deformation. Despite being only preliminary (as based on a sub-set of the overall planned simulations), the maps clearly depict the most hazardous sectors of the volcano, which have been identified by applying the coupled modelling-GIS method here described.

Aggregate queries are useful in the context of sensor networkbased
systems as they retrieve knowledge from huge amounts of
summarized readings to be exploited for knowledge discovery
purposes. Actually, data representation and query models are
important limitations in managing sensor network data, since
streams produced by sensors are theoretically unbounded. In this
paper, we present a Grid framework, based on the data
compression paradigm, which allows us to provide approximate
answers to aggregate queries on summarized sensor network
data. We also present our experience in the context of a real-life
system focused on the management of environmental sensor
network data.

Abstract

susceptibility and hazard ...
A method for mapping mud flows and lava flows, and for evaluating related
susceptibility and hazard has recently been tested at different study areas of Southern Italy
(located in Campania, Calabria, and Sicily), which have repeatedly been affected by
damaging events in historical time. The approach is based on numerical models, GIStechniques,
geo-environmental and historical evaluations. Results have been obtained
through a statistical approach by simulating a large number of events on a cluster.
Employed cellular automata models have first been calibrated, either manually (by trial and
error) or by means of Genetic Algorithms, and then validated against past flow events that
occurred in the same study areas, or in similar geo-environmental settings. Simulations
have been quantitatively evaluated with respect to real cases by means of two distinct
functions of fitness based on 1) the affected areas for mudflows, and on 2) affected areas
and duration for lava flows. Aiming at susceptibility/hazard assessment, a grid of possible
sources has been hypothesised on the basis of historical/geological knowledge and statistics
of past events. For each source, a high number of simulations has been planned by adopting
combinations of sources' and materials' characteristics. Probabilities of activation,
empirically based on past events, have been assigned to each source of the grid by
considering its location and geological information. Different probabilities have also been
assigned to each "type of event" by taking into account their observed historical
frequencies. Two different types of maps were realized in a GIS_ 1) a susceptibility map,
realised by simply counting the frequencies of flows affecting each site; 2) a hazard map, in
which probabilities have been "empirically" attributed to each simulation based on location
of sources and types of event. Preliminary results (based on a subset of the overall planned
simulations) clearly depict the most susceptible and hazardous sectors.

Damaging Hydrogeological Events are defined as periods during which phenomena, such as landslides, floods and secondary floods, cause damage to people and the environment.
A Damaging Hydrogeological Event which heavily damaged Calabria (Southern Italy) between December 1972, and January 1973, has been used to test a procedure to be utilised in the zonation of a province according to damage susceptibility during DHEs. In particular, we analyzed the province of Catanzaro (2391 km2), an administrative district composed of 80 municipalities, with about 370,000 inhabitants.
Damage, defined in relation to the reimbursement requests sent to the Department of Public Works, has been quantified using a procedure based on a Local Damage Index. The latter, representing classified losses, has been obtained by multiplying the value of the damaged element and the percentage of damage affecting it.
Rainfall has been described by the Maximum Return Period of cumulative rainfall, for both short (1, 3, 5, 7, 10 consecutive days) and long duration (30, 60, 90, 180 consecutive days), recorded during the event.
Damage index and population density, presumed to represent the location of vulnerable elements, have been referred to Thiessen polygons associated to rain gauges working at the time of the event.
The procedure allowed us to carry out a preliminary classification of the polygons composing the province according to their susceptibility to damage during DHEs. In high susceptibility polygons, severe damage occurs during rainfall characterised by low return periods; in medium susceptibility polygons maximum return period rainfall and induced damage show equal levels of exceptionality; in low susceptibility polygons, high return period rainfall induces a low level of damage.
The east and west sectors of the province show the highest susceptibility, while polygons of the N-NE sector show the lowest susceptibility levels, on account of both the low population density and high average rainfall characterizing these mountainous areas.
The future analysis of further DHEs, using the tested procedure, can strengthen the obtained zonation. Afterwards, the results can prove useful in establishing civil defence plans, emergency management, and prioritizing hazard mitigation measures.

From the antiquity, the hilly landscape around the city of Axum in northern Ethiopia has been terraced and extensively used for agriculture purposes. Impacts of the ard plough on protruding and/or buried boulder at a depth less than the tillage depth produce scratches on their sides or their top. The spatial relationship among plough marks and rock surface orientations gives information on the ploughing direction, whereas the relative height from the present ground surface to the top of the marks and information on the age of cultivation can be used to assess soil loss rates. Parameters to define plough mark orientation were defined and measured in the field on boulders with plough marks within a study terrace located in an archaeological area with an approx of 2040 year age. These parameters are height from the ground, dip, slope and frequency.
The measurements also show that the initial terrace slope was steeper than the present one confirming the effectiveness of the traditional terracing practice in soil conservation because of the low soil erosion rates assessed over a so large time interval. For the main time intervals of the Axumite history, corresponding to the rise and fall of the Axumite civilization and to variable conditions of human pressure on the land, the maximum erosion rates inferred are of the order of 3.4 Mg/ha/y.. This result is compared with erosion rates calculated with other methods reported in literature (e.g. PSIAC) and field measurement on terraces in the same region leading to values coinciding with those obtained by the plough marks method.

The work aims at identifying susceptible areas and pluviometric triggering scenarios at a regional scale in Calabria (Italy), with reference to
shallow landsliding events. The proposed methodology follows a statistical approach and uses a database linked to a GIS that has been created to
support the various steps of spatial data management and manipulation. The shallow landslide predisposing factors taken into account are derived
from (i) the 40-m digital terrain model of the region, an ~15,075 km2 extension; (ii) outcropping lithology; (iii) soils; and (iv) land use. More
precisely, a map of the slopes has been drawn from the digital terrain model. Two kinds of covers [prevalently coarse-grained (CG cover) or finegrained
(FG cover)] were identified, referring to the geotechnical characteristics of geomaterial covers and to the lithology map; soilscapes were
drawn from soil maps; and finally, the land use map was employed without any prior processing.
Subsequently, the inventory maps of some shallow landsliding events, totaling more than 30,000 instabilities of the past and detected by field
surveys and photo aerial restitution, were employed to calibrate the relative importance of these predisposing factors.
The use of single factors (first level analysis) therefore provides three different susceptibility maps. Second level analysis, however, enables
better location of areas susceptible to shallow landsliding events by crossing the single susceptibility maps.
On the basis of the susceptibility map obtained by the second level analysis, five different classes of susceptibility to shallow landsliding events
have been outlined over the regional territory_ 8.9% of the regional territory shows very high susceptibility, 14.3% high susceptibility, 15%
moderate susceptibility, 3.6% low susceptibility, and finally, about 58% very low susceptibility.
Finally, the maps of two significant shallow landsliding events of the past and their related rainfalls have been utilized to identify the relevant
pluviometric triggering scenarios. By using 205 daily rainfall series, different triggering pluviometric scenarios have been identified with reference
to CG and FG covers_ a value of 365 mm of the total rainfall of the event and/or 170 mm/d of the rainfall maximum intensity and a value of
325 mm of the total rainfall of the event and/or 158 mm/d of the rainfall maximum intensity are able to trigger shallow landsliding events for CG
and FG covers, respectively.
The results obtained from this study can help administrative authorities to plan future development activities and mitigation measures in
shallow landslide-prone areas. In addition, the proposed methodology can be useful in managing emergency situations at a regional scale for
shallow landsliding events triggered by intense rainfalls; through this approach, the susceptibility and the pluviometric triggering scenario maps
will be improved by means of finer calibration of the involved factors.

Daily runoff from 27 plots (5 m × 2 m) recorded during two rainy seasons in the Tigray highlands (Ethiopia) were analysed together with daily rainfall to calculate runoff curve numbers for hillslopes covered by semi-natural vegetation in varying stages of vegetation restoration. Curve number model parameters were derived using a least squares fitting procedure on the collected rainfall-runoff datasets. Curve numbers varied from 29 to 97. Land use type was an important explanatory factor for the variation in curve numbers, whereas hydrologic soil group was not. Curve numbers were negatively correlated with vegetation cover. Taking into account antecedent soil moisture conditions did not improve runoff prediction using the curve number method. As runoff prediction was less accurate in areas with low curve numbers, two separate regression functions relating curve numbers with vegetation cover were proposed for different land use types.
