remains of stucco ...
propose three articles in succession by the Republic over the last two days. perplexes me the fact that the three phenomena that have invested in the two regions must be connected by the bridge. Also interesting is the fact that the A3 was closed for 60 miles and the stretch that actually connects to the area where it should be based on the Calabrian pylon of the bridge over the Strait - nice coincidence!
The finding becomes dramatic when you consider that the first of landslides is high risk area PAI-geological (and indeed !!!!) and the darkened, especially in the area of \u200b\u200bTropea, for the modernization of the Salerno - Reggio Calabria (A3) was made the request for change in the PAI. I remain
stucco face of so much indifference and starvation, and I'd like to know if and how they respond technicians of public bodies that deal with these crazy concessions. Obviously
reflections and comments do not stop this, but for now the anger is so great and the clarity is not as much.
Bad weather, a landslide on the A3 CosenzaDue dead and 5 wounded. One is very serious
Geologists: "Our alarms regularly ignored"
Cosenza - buried by mud in their car on the highway. E 'with two dead and five wounded, in a very serious, the budget of a landslide that has invaded in the night both carriageways of the motorway A3 Salerno-Reggio Calabria motorway between junctions of Rogliano Altilia and Grimaldi. A mass of mud and debris come off for rain from a hill that has buried a van moving south on which they traveled seven people, the coach of a football team and six players. Two boys managed to escape while two others were pulled alive after several hours of work. For two other people but there was nothing to do. One of the victims called Nicolino Palisade, 59 years old from Cotronei (Crotone). If she was released from mud and debris from the northbound carriageway, the teams of firefighters and Anas are continuing work to also traveled the other lane. At the time, according to what has been learned by the staff of Anas that is in place, there are other means and people dragged from the mud. The man is hospitalized in serious condition with two other people in the department of neurosurgery hospital in Catanzaro. Two other wounded are in the hospital in Lamezia Terme, but their conditions are not severe. Also in Cosentino two people were injured while on board of their cars, they were crossing a bridge over the river crater that has suddenly collapsed because of river dell'esondazione Crati. Have taken place on the firefighters who rescue the two drivers to support them in the hospital Cosenza. Their conditions are not of concern. Alarms ignored. "We have repeatedly warned of the devastation of Calabria, but no one has ever heard. And here's what happens," says the president of the geologists of Calabria, Paul Cappadona. "What happened last night is the third world. In Calabria there is a devastated land, but every time I try to raise the institutions we come up against the glass ceiling." The case is also addressed by President of the Region Agazio Loiero. The motorway Salerno-Reggio Calabria is a domestic case, he said, "and in fact, I have raised no more than two months ago. But right now there are dead. There are families ... So, I do not want you to be an issue that can play in any instrumental way. Before any discussion, you understand just what happened. Certainly, there will be time to do other considerations ".
Bad weather causes a landslide Tropeastrage avoided by a whisker
Among the new settlements and precautionary measures closed 60 km of A3 Salerno-Reggio CalabriaSmottamento also on the power rail-Battipaglia, broken links
A landslide in Calabria Vibo
- A few days after landslide that killed two people on the Salerno-Reggio Calabria , the bad weather of recent days threatened to cause another tragedy in Calabria. huge landslide broke away last night from the ridge overlooking Tropea, famous tourist town on the Tyrrhenian coast, ending below the provincial and then to the sea. The crash occurred around 4. At that time, also given time, there were no vehicles in transit. Place on the fire and bulldozers that are trying to clear the debris that came close to the hotel collapsed "Nettuno". Invaded the avenue leading to the permanent position of the State Police, closed to traffic. Other minor landslides are reported across the Vibo Valentia province. Today, meanwhile, in Catanzaro, the funeral will be held the second victim of the disaster on Sunday A3, in Cosenza. Meanwhile on the same highway remain many hardships, amplified by new settlements of the ground. There are now some sixty kilometers closed to traffic due to landslides or rock falls. In addition to the North-Falerna stretch Coseley, yesterday afternoon, the prefect of Reggio Calabria Francesco Musolino has ordered the closure of the tract Scilla-Villa San Giovanni. Today will begin geological surveys on the area and at the time, sources said the prefecture, it is impossible to make predictions on the reopening. The result is that on the road 18 at the time the only viable option to the Calabrian north-south links, there are traffic jams and inconvenience. Another landslide caused by heavy rains in recent days has spread to the tracks between stations Romagnano (Salerno) and Wall Bella (Potenza), forcing rail line to stop the power-Battipaglia. Trenitalia has scheduled a bus replacement plan for up to 15 hours for the connections between Taranto, Potenza, Salerno and Battipaglia. Meanwhile, railroad engineer of the state are working to clear the track with debris. Also in this case was, however, avoided the worst. Last night, the regional train 12439 Salerno-Power reported it damaged in collision with a rock, but fortunately there have been bruised between the eight passengers were aboard. Big problems they are causing the bad weather in Naples where Coroglio descent was closed to traffic in both directions and a family was evacuated as a precaution after the collapse of the top of the ridge from the lateral side of the hill of Posillipo occurred last night. Meanwhile in Sicily are still trying to identify the responsibilities of tragedy yesterday when a landslide killed two workers in Caltanissetta. Now is the confirmation that the Office of the City engineer had ordered the building blocks of Via Mario Gori to secure the perimeter wall of the complex collapsed Saturday afternoon. The ordinance dates back to October 29 last year, following an inspection conducted following the technical reports on injuries of the wall. Hence the order to consolidate the wall with operations to be performed immediately, while the City had said the unavailability of the rear of the building Because of the state of grave danger all'incolumitĂ the private and the public.
Landslide kills two workers in the petrochemical CaltanissettaTerza victim of Gela
Mayor: "The Civil Defence knew, lacked the funds" The prosecutor opened an investigation to determine responsibility in the collapse
The site of the landslide
CALTANISSETTA - A part of the mountain is in Caltanissetta overwhelming landslide that two workers were performing work on a funnel Mario Gori, in the district Redeemer. Rescuers have pulled out bodies buried under earth and mud. The third worker who was working with two companions was saved because he left the hand just before the collapse. The victims of the landslide in nissen are Holy Notarrigo, 37, owner of the company that was doing the work of Caltanissetta, and Happy Baldi, 19, originally from a town in the province. The body of Notarrigo was extracted immediately from the mud, while the Baldi has been found by rescuers after nearly an hour of digging. The prosecutor of Caltanissetta opened an investigation into the landslide, against persons unknown at the time, to establish responsibility in the collapse. The landslide, which occurred in a condominium on the hill Sant'Anna, was caused by heavy rains in recent days. The area had already been the scene of landslides and the alarm was high, so that a dozen families were driven from their homes. The situation was worrying, as confirmed the city's mayor, Salvatore Messana, who announced that he will declare a day of mourning. "It 's really a tragedy what happened. One thing is sure - said the mayor - the hydrogeological situation of Caltanissetta is serious. I have long urged the Civil Defence to take action on the hill but was not Sant'Anna done anything because I was told that lacked the necessary funds to the work of consolidation '. " The work had been commissioned by the condominium after the Commune, to avoid danger, had issued an order prohibiting the transit. In the yard were operating bulldozers and other mechanical means. The vibrations, according to one hypothesis, may have facilitated the posting of a rocky hill, already made unstable by the rains of recent days. According to a first reconstruction of the accident, the two were working on behalf of the apartment building on Via Mario Gori, and a small crane were trying to dig a canal to bring water into the storm sewer. For several weeks, ever since it started to rain so incessant, the area has experienced several failures of the soil with water infiltration, so the building had decided to make the channeling of water to avoid damage to the building. Just the two workers began digging, the concrete retaining wall collapsed and swept them. Messana The mayor stressed that "are several areas of cities affected by hydrogeological and hours are 60 families housed in hotels after hydrogeological problems occurring in the area of \u200b\u200bSt Anne and St Barbara because of the phenomenon of volcanoes.

Why Does Running Make Your Periods Change
The instability in Nicaragua (Alessandro Davì)
In a time when we should increase awareness of public opinion on the issue of the hydrogeological and the idea of \u200b\u200bslope instability This blog seems adequate and appropriate. Even because we are living on this side or we build structures, often recklessly, even if sometimes touted as the projects of primary importance for the industrial and economic development in a specific region.
Although my studies have approached questions of different types do not deny that the geomorphology in general I have always had a strong interest, interest ancestral brings me back to my childhood and my love for geography.
During my studies I had to get close to gravitational phenomena as (or related to) collapse, colamenti and (especially) lahar. Everything was channeled to one of my study on the phenomenon of instability in volcanic environment. And 'obviously no need to stress as eruptive activity (especially of Plinian type) can cause big changes beyond the purely regional geological, volcanological and petrographic specific interest. For example, the age-old question of whether we should consider the "lahar" a purely event-related volcanism (perhaps to a secondary volcanism) or a mechanism closely related to the geomorphology of the region under consideration. Fragmentation of magma during Plinian eruption can then play a key role in weaving and cohesion of the loose sediment: the Sarno landslide of 1988 was a classic case of such a harmful combination: pyroclastic material rich in SiO2, fine, tinted made unstable by rainwater and the activity man.
Many of you know that one of my field of inquiry was, of course for study and academic training, mainly Central America and Nicaragua. In addition, since Leonardo says in its article, the use of technologically advanced machinery and equipment, would also be interesting to compare the methodologies of research and experimental approach in a country relatively new technologies such as Italy and a country like Nicaragua which has strong motives in wanting to fill some gaps in knowledge concerning one of its most pressing problems as the hydrogeological. Recall that Nicaragua is a country of tropical rainfall with has a high range of values \u200b\u200bbetween the "half wet" and "half dry". Imagine the conditions of fixity and strength of its sides to the arrival of the first six months after torrential rains impressive total of drought.
Landslides on which I dwelt in Nicaragua (especially lahar) mainly concern the area of \u200b\u200bManagua and the area of \u200b\u200bSan Cristobal and Casitas volcano (in the north-west of the country). I attach to this article and some interesting pictures you will notice that some phenomena are extremely important posting.
The photo (1) was taken by myself during a trip to the aforementioned S. Cristobal (left) and Casitas (right) is remarkable that opened the gash on the right for a gravitational phenomena linked to the activity of Hurricane Mitch in 1998. The event can be defined as a debris avalanche that has gaping cold the slope, creating a discontinuity in the mantle of vegetation. The picture may not make the idea and grandeur of the phenomenon but, trust who has been there is something awesome to see.
The photo (2) shows the same event, but perhaps makes a better idea of \u200b\u200bthe material deposited in the foothills, this picture is derived from a publication INETER (Nicaraguan Institute Estudios Territoriales).
The photo (3), always taken by me, shows another volcano in Nicaragua: the Cerro Negro. We look like a landslide, probably synchronous Strombolian-type eruptive activity, has resulted in the accumulation of juvenile material (ash and slag) would make the slope unstable with subsequent landslide, although I would not call it a real lahar . From a purely particle size could be a dripping but there is no certainty that there was a simultaneous wetting of the deposit due to meteoric activity.
The photo (4) shows the situation at the foot of Cerro Los construction Martinez, a relief that washes the western outskirts of the city of Managua. It is obviously very interesting because it shows the urban situation (obviously messy and chaotic) at the foot of the slopes so unstable. Excessive deforestation and reconstruction reckless and disorderly in the city after the earthquake of 1972 (which destroyed almost) make it highly probable event trigger catastrophic gravitational especially interested in certain neighborhoods of crumbling suburbs. Managua is a city of 1,500,000 inhabitants.
Some Italian NGOs were tasked with developing a micro-zoning map of the city of Managua risk: it was developing a GIS in order to correlate each batch of the city with the main sources of risk (earthquakes, rainfall, landslides, floods, volcanic volcanic) and possibly develop a hazard map in order to carry out infrastructure improvements and preventive works. Great difficulties to the development of this project were caused by bureaucratic delays and inadequate geological knowledge of the area. Unfortunately I do not know the status of implementation of this project that could definitely be of any real and concrete.
It (5) obviously does not need to comment further and highlights the highly precarious situation of the suburbs addossatesi uncontrollably in highly unstable slopes.
In many publications and studies by researchers in many European, American and Japanese, not about methodologies for monitoring and control, but are treated only cartographic analysis and in the geomorphological GIS. This innovative study methodology could be 10 or 15 years ago, while today a development in GIS is considered an introductory stage to a more complete plan of instrumental control and monitoring via satellite.
The proposal that I make in this blog is to weave a plot against linked to different types of landslides on the basis of what we studied and observed, and not pausing only to the Alps to Sicily, but also from areas' intense volcanic activity as the Central American arc. Could carry out projects or discussions about the most advanced monitoring techniques that could take root in areas not yet accustomed to a certain type of study.
The man, over the centuries has used its best energies in achieving total knowledge of reality with which it interacts. Because of our intellectual and sensory limitations we can not know reality in its absolute essence, because we (or we assume) to make the laws more or less constant and universal through empirical studies, related to the phenomena that we can only observe. Ergo, the model will be for us always an approximation, but will never be the carrier for a full airing.

Welcome New Member Letter For Church
The laser scanning for monitoring man-made structures
generally use the laser scanner for many different applications and still on areas such as medium-scale landslides, landfills and quarries. The project under consideration is rather consisted in verifying the change of the crack of some houses as a mirror of the evolution of a widespread collapse in a town in Lombardy. Since the project is currently still in progress, I will confine myself to the description of volunteer activities and omit the names of places.
However, this town of Lombardy is characterized by a collapse to a circumscribed area of \u200b\u200bthe municipality particularly karstified. In these places has risen a not insignificant number of homes that, over time have begun to express widespread subsidence, inclinations of the walls (even those carriers) is also very deep cracks that often have eroded structures. For obvious reasons the council was unable to intervene directly on private properties and for this reason it was decided to implement a particular action on soil protection and avant-garde: the excavation a series of trenches along the roads of the country from which to depart a series of micro orizzonatli radial on which the houses could take the weight off. Far be it from me on assessments about the quality of the project (not my job) I was still asked if it was possible to make assessments (in fact non-partisan in conjunction with the geotechnical monitoring conducted by the firm in charge of piling) on \u200b\u200bthe move recorded from the homes during the excavations and in the aftermath of the regional planning. My monitoring proposal was to make three campaign tracking laser scanner from the ground.
The first campaign has in fact given the initial crack pattern (I think I may have devastating but accurate idea of \u200b\u200bthe house too!). Then, after six months I have made, on the same houses and the same points of taking a new set of scans. The quality and detail of the scans was a very dense number of points, in order to obtain a realistic picture of great detail and also those cracks millimeter. Following the scans I have since carried out the photos with the built-in laser fotocmera. The defenses of processing (carried out by the JRC 3D Reconstructor - http://www.gexcel.it/ ) consisted initially in the town of referencing in all scans and all images to create three-dimensional models are similar or totally overlapping for the two sets of scans. Then I made two types of test: the automatic inspection of the two meshes (triangulations of automated comparison of point clouds) to produce a guideline with regard to areas where the clouds of points were not perfectly overlapping. The problem, however, as a result of this development was born when the reliability dell'inspection is in fact an order of magnitude as the size of the change in open fractures that I expected. Result: it is true that in some cases the inspection marks a change in me, but that variation can be even within intrinsic error of measurement, or alternatively if the inspection marks nothing I can also not see anything related to the fact that changes in position are numerically inferior to the definition of the scan or the inspection itself. How to work then? In this sense, the literature, and also the excellent editing programs I have come to meet. It 's possible to create digital orthophotos of my scans orthometric just putting themselves in position, and in particular made the mesh (triangulation of the scan) and those with digital photos (thus obtaining a three-dimensional pictures) for both series may be obtained by the Broadcasting orthophotos of the first set and second set. Through the program Kubit ( http://www.gexcel.it/ ) was then possible to export each of the digital orthophotos and replace my object in different levels: level ortho first scan, second scan ortho level, the crack level 1 (derived from copying by hand in each of the slots of the first set of scans) and at the crack 2 (obtained in the same way.) After this operation, the result is a possible comparison of crack patterns of the two series of scans at all points where I proceeded to detect the cracks.
results. Areas of variation of the crack corresponding to those too superficially by automatic inspection in Recostructor (index of this good product quality information), in particular, it was possible to verify a substantial change of the crack in terms of number of cracks per unit area for extension of the cracks themselves. The major fissures in fact have increased their presence and longitudinal data, while smaller ones have generally retained their extension.
The data were then supported by those of fessurimetri.
Reflection. The fessurimetri are a very reliable and also permit the continuous monitoring of the cracks, the limit of the use of fessurimetri however, is that if a new slot opens to two centimeters from the old one and also with a size of 50 cm the fessurimetro does not realize it. Hence the validity of the laser scanner data in these conditions. Obviously the costs are different in terms of time and effort although still in a telemetry system for a number of cracks even half of those observed with the laser results with fessurimetri certainly more costly.
Thoughts?
