Forecasting the time, nature, and impact of future eruptions is difficult at volcanoes such as Mount Etna, in Italy, where occur from summit on flanks, affecting areas distant each other. Nonetheless, identification quantification risk new are fundamental for mitigating potential human casualties material damage. Here, we present results application a methodology to define flexible high‐resolution lava invasion susceptibility maps based reliable computational model simulating flows Etna...
Abstract. On 15–16 December 1999, heavy rainfall severely stroke Campania region (southern Italy), triggering numerous debris flows on the slopes of San Martino Valle Caudina-Cervinara area. Soil slips originated within weathered volcaniclastic mantle soil cover overlying carbonate skeleton massif. Debris slides turned into fast flowing mixtures matrix and large blocks, downslope eroding increasing their original volume. At base slopes, impacted urban areas, causing victims severe...
GA SAKe is a linear, steady-state hydrological model. It employs Genetic Algorithms to predict the timing of triggering landslides, based on rainfall and previous activations. Calibration provides discrete kernels, that allow analyse even complex geohydrological conditions, with high level detail. Once validated, mobility function model allows landslide The release 2.0, here presented, introduces powerful computational engine, couple relevant modules: validation tool, unique non-linear...
This paper presents the latest developments of deterministic Macroscopic Cellular Automata model SCIARA for simulating lava flows. A Bingham-like rheology has been introduced first time as part Minimization Algorithm Differences, which is applied computing outflows from generic cell towards its neighbours. The hexagonal cellular space adopted in previous releases mitigating anisotropic flow direction problem replaced by a–Moore neighbourhood–square one, nevertheless producing an even better...
ABSTRACT The landslide inventory of the Picentino basin was realized at 1:25,000, with focus on main geomorphological features affecting slope stability. It is based different sets air-photos (scales 1:33,000–1:18,000, dated up to 1998), and field surveys. Among shallow landslides, channelized debris flows strongly prevail, originated as slides moderately steep slopes. Further sectors are affected by deeper movements greater extent. Items related tectonics, erosion processes, anthropized...
Landslides cause fatalities, widespread damages and economic losses. Quite frequently, they are triggered by rainfall. Many studies have investigated the relationships between rainfall characteristics landslide events. This paper reviews two main approaches, physical hydrological, for modelling such relationships. In approach, influence of on slope stability is commonly analysed in terms groundwater infiltration, pore pressure changes balance shear stresses resistances, therefore a...
A severe rainfall event occurred in southern Calabria between 29 October and 2 November 2015, causing two deaths serious damage to transport infrastructure. Widespread slope erosion thousands of shallow landslides were triggered on the slopes, combined with flooding debris along streams. Rains recorded by regional gauge network national radar monitoring system analysed means Kriging techniques. Ground effects surveyed field, mapped using post-event air photos taken coastal sector. Shallow...
Abstract. Lahars are erosive floods, mixtures of water and pyroclastic detritus, known for being the biggest environmental disaster causing a large number fatalities in volcanic areas. Safety measures have been recently adopted threatened territories by constructing retaining dams embankments key positions. More disastrous events could be generated difficulty maintaining these works efficiency changed risk conditions originating from their presence effects functioning. LLUNPIY/3r, version...
The individuation of areas that are more likely to be affected by new events in volcanic regions is fundamental relevance for the mitigation possible consequences, both terms loss human life and material properties. Here, we describe a methodology defining flexible high-detail lava-hazard maps technique validation results obtained. relies on: (i) an accurate analysis past behavior volcano; (ii) version SCIARA model lava-flow simulation (based on macroscopic cellular automata paradigm); (iii)...
Abstract The use of thematic volcanic hazard maps is essential for policy managers and administrators in land planning to determine the best form action during emergencies. In particular, are a key tool emergency management used describe threat expected at certain location event future eruptions. We applied latest version SCIARA lava flow cellular automata model using parallel computing through general purpose graphics processing units technology derive Mt Etna, Sicily. methodology relies on...
Cotopaxi volcano is one of the most studied and surveyed volcanos in world because repetition of the 1877 catastrophic lahar invasion, not implausible, threatening now more than 100,000 persons. A reliable forecasting tool very important for projecting security measures. LLUNPIY a Cellular Automata model simulating lahars terms complex system evolving on base local interaction. Here, extension applied to event primary lahars, after successful simulation some secondary...
