Abstract

Relationships between drainage network and landslides distribution have been investigated by classical and quantitative
geomorphological analysis in an intramontane valley (i.e. the upper valley of the Sinni River) of the southern
Italian Apennines in order to assess the influence of fluvial erosion on mass movements processes. The 70 km2-
wide test-area is mainly characterized by crystalline-metamorphic rocks affected by very low grade metamorphism
and underwent high uplift rates during Quaternary times. We recognized and mapped 537 landslides through the
stereoscopic interpretation of one set of about 20 panchromatic aerial photographs 1_33000 scale. Landslides were
classified according to both type of movement and relative age. Relative age of landslides was determined according
to morphologic appearance (freshness) of the slope failures and also using cross-cut geomorphological
relationships. We recognized 3 classes of landslides called_ (i) "very old" (possible first-failure landslides), showing
to be mostly linked to a different climatic and gemorphological setting than the present one; (ii) "old", slope
failures not so fresh but neither obliterated by fluvial erosion or by subsequent mass movements; these mass movements
developed mostly in slopes already affected by large, deep seated and very old landslides; (iii) "recent",
landslides occurred not so far with respect to the age of the aerial photographs (1991), or mapped through a field
reconnaissance survey made in March-April 2009. Generally, these landslides are shallow and triggered by intense
and prolonged rainfall. We detected and mapped 37 new landslides after a long rainfall period during the
winter 2008-2009. In order to evaluate the role of the fluvial processes on landslides distribution, a quantitative
geomorphological analysis of the drainage network has been performed. In particular, the degree of planimetric
organization of the fluvial network has been evaluated by the analysis of several morphometric indices, which
assume high values in area strongly perturbed by tectonics and/or mass wasting processes. We argued that the
medium-high hierarchical anomaly density values can be mostly due to the presence of landslides disturbing the
regular development of the fluvial network. Moreover, denudation rates related to recent/active geomorphological
system have been obtained by estimating the amount of suspended sediment yield of channels on the grounds of
empirical relationships based on the hierarchic arrangement of the fluvial network. In the study area, denudation
rates are settled on value of about 0,2 mm/y, whereas the Quaternary uplift rates are between 0.93 - 1.57 mm/y.
We argue that the high uplift rate of recent times is a disturbing element within the recent morphogenesis. On the
basis of the discussed data, large mass movements in the study area are mainly triggered by Quaternary tectonics,
with litho-structural and morpho-climatic factors that assumed a minor role.

Abstract

In Italy, landslides are frequent and widespread geomorphological phenomena triggered primarily by intense or
prolonged rainfall. Using a variety of information sources, we have compiled a national catalogue of 1200 rainfall
events that have resulted in documented landslides in Italy, between 1841 and 2010. The catalogue represents
the single largest collection of information on rainfall-induced landslides in Italy. We exploit the catalogue to
determine empirical intensity-duration (ID) rainfall thresholds for the possible occurrence of slope failures in
Italy (national ID thresholds). For the purpose, we use two independent and complementary statistical methods_
(i) a Bayesian inference method, and (ii) a Frequentist method. The national ID thresholds are currently used
in an operational landslide warning system to forecast rainfall-induced landslides in Italy. The Italian national
Department for Civil Protection uses the system routinely in an attempt to mitigate landslide risk in Italy.
From the available national catalogue, we select three regional subsets of rainfall events with landslides in central
Italy, including_ (i) 175 events in the Marche region, (ii) 140 events in the Umbria region, and (iii) 84 events
in the Abruzzo region. First, for each region, we use the selected subsets of rainfall events with landslides to
determine separate regional ID thresholds. Next, using 1_500,000 scale regional lithological maps, we determine
the main lithological types in the areas where the rainfall induced landslides were reported. Lastly, we use the
rainfall and lithological information to investigate the role of lithology on rainfall thresholds for the possible initiation
of landslides in central Italy.We further attempt to generalize the obtained results at the national scale, in Italy.

Abstract

We used remote sensing data to define new rainfall thresholds for the possible occurrence of landslides in Marche and Umbria regions, central Italy. Remote sensing data are provided by NASA and the estimated rainfall is cumulated every three hours in a regular grid of 0.25° × 0.25°. We exploited a catalogue of temporal and spatial information on landslides triggered by rainfall in the study area in the period 2002-2010. For each slope failure in the catalogue, we calculated the cumulated rainfall E (mm) and the duration D (h) of each rainfall event that triggered one or more landslide, using both remote sensing data and measurements obtained from a rain-gauge network. The rain-gauge network in the study area includes 123 stations and the rainfall is cumulated every hour. Finally, we obtained two data sets of empirical rainfall conditions (D, E) that triggered landslides and we defined the corresponding rainfall thresholds for remote sensing data and for rain gauge data. We used a Frequentist method and assumed that the threshold curve is a power law E = ? × D^?, where ? is a scaling constant (the intercept) and ? is the shape parameter that defines the slope of the power law curve. This method allows to define rainfall threshold corresponding to different exceedance probabilities. We observed that the threshold for remote sensing data is permanently lower than the threshold obtained with rain-gauge measurements. Finally, we found a relationship between the two thresholds. This is important because it permits the use of sensing precipitation data to obtain rainfall thresholds for the possible occurrence of landslides in those areas where rain gauge measurements are insufficient, or inexistent.

The paper presents a novel automatic early warning system to remotely monitor areas of archaeological and cultural interest from the risk of fire. Since these areas have been treasured and tended for very long periods of time, they are usually surrounded by old and valuable vegetation or situated close to forest regions, which exposes them to an increased risk of fire. The proposed system takes advantage of recent advances in multi-sensor surveillance technologies, using optical and infrared cameras, wireless sensor networks capable of monitoring different modalities (e.g. temperature and humidity) as well as local weather stations on the deployment site. The signals collected from these sensors are transmitted to a monitoring centre, which employs intelligent computer vision and pattern recognition algorithms as well as data fusion techniques to automatically analyze sensor information. The system is capable of generating automatic warning signals for local authorities whenever a dangerous situation arises, as well as estimating the propagation of the fire based on the fuel model of the area and other important parameters such as wind speed, slope, and aspect of the ground surface.

We exploited Differential Synthetic Aperture Radar Interferometry (DInSAR) to investigate the geographical and the temporal pattern of ground deformations in the Ivancich landslide area, Assisi, Italy, in the 18.4-year period April 1992 - September 2010. We used SAR data obtained by the European Remote Sensing (ERS-1/2) satellites in the period April 1992 - July 2007, and SAR data captured by the ASAR sensor on board the Envisat satellite in the period October 2003 - September 2010. We used the Small Baseline Subset (SBAS) technique to process the SAR data, obtaining full resolution measurements for multiple radar targets inside and outside the landslide area, and the history of deformation of the individual targets. The geographical pattern of the ground deformation was found consistent with independent topographic information. The deformation time series of the individual targets were compared to the rainfall history in the area. Results revealed the lack of an immediate effect of rainfall on the ground deformation, and confirmed the existence of a complex temporal interaction between the rainfall and the ground deformation histories in the landslide area. Availability of very long, spatially distributed time series of surface deformation has provided an unprecedented opportunity to investigate the history of the active landslide area.

Abstract
A coupled model has been developed to simulate, at watershed level, landslides and debris flows ...
A coupled model has been developed to simulate, at watershed level, landslides and debris flows induced by a severe typhoon (tropical cyclone) in Taiwan. The model comprises a landslide susceptibility model to predict
landslide occurrence, an empirical model to select debris-flow initiation points, and a debris flow model to simulate the transport and deposit of failed materials from the identified source areas. In raster format
with a 10 m spatial resolution, the model output includes unstable cells, debris-flow initiation cells, debrisflow velocities, runout paths, and deposition zones. The model was first tested and calibrated in a small area, where the damage by landslides had been investigated and recorded. It was then applied to a watershed, and the simulation results were validated by comparing them with a landslide/debris-flow inventory
map prepared from satellite images using a multiple change detection technique. Model test and validation results confirm the usefulness of the model in predicting the number and size of affected areas (landslides
and runouts combined), runout path, and volume of runout deposits. It is a common practice in Taiwan to separate landslide and debris-flow inventories and to study debris flows only in select drainage basins.
This study suggests that landslide and debris flow should be modeled as a sequential process for efficient watershed management.

Abstract
Rock fall from limestone cliffs at Timpanogos Cave National Monument in American Fork Canyon east ...
Rock fall from limestone cliffs at Timpanogos Cave National Monument in American Fork Canyon east of Provo, Utah, is a common occurrence. The cave is located in limestone cliffs high on the southern side of the canyon. One fatality in 1933 led to the construction of rock fall shelters at the cave entrance and exit in 1976. Numerous rock fall incidents, including a near miss in 2000 in the vicinity of the trail below the cave exit, have led to a decision to extend the shelter at the cave exit to protect visitors from these ongoing rock fall events initiating from cliffs immediately above the cave exit. Three-dimensional rock fall simulations from sources at the top of these cliffs have provided data from which to assess the spatial frequencies and velocities of rock falls from the cliffs and to constrain the design of protective measures to reduce the rock fall hazard. Results from the rock fall simulations are consistent with the spatial patterns of rock fall impacts that have been observed at the cave exit site. © 2011 Springer-Verlag.

Abstract

We evaluate rock fall hazard along the railway corridor to Jerusalem, Israel, in the Soreq and Refaim valleys. For the purpose, we use a combination of historical information on past rock fall events, field surveys aided by the interpretation of aerial photographs, and numerical rock fall modeling. Historical information indicates that on July 11, 1927 an m L 6.2 Dead-Sea transform earthquake caused rock falls in the studied area. The seismically induced rock falls damaged the railway tracks. Field observations revealed that the source area for the 1927 failures was located in the Aminadav formation, at the contact with the Moza formation. At the stratigraphic contact, rock blocks 100-101 m3 in size are formed as a result of tensile stresses and associated fracturing in the dolomite of the Aminadav formation, combined with continuous creep of the blocks on the marl of the underlying Moza formation. We use topographical, geological, and geomorphological information to calibrate a three-dimensional numerical simulation of rock falls in the studied area. We use the results of the numerical modeling, and additional independent information, to assess rock fall hazard and the associated risk in the Soreq and Refaim valleys. Results indicate that in the studied area, rock fall risk to the railway line to Jerusalem is due primarily to Dead-Sea transform earthquakes, with m L > 6. We identify nine sections of the railway line where rock fall risk exists, for a total length of 2.5 km. We further note that seismically induced rock falls can produce damage to the road network in the studied area, make it difficult or impossible for earthquake casualties to reach hospitals in Jerusalem. We conclude offering recommendations on how to mitigate the risk posed by earthquake-induced rock falls in the studied area.
