File Name: causes and effects of landslides .zip
The term landslide or, less frequently, landslip    refers to several forms of mass wasting that may include a wide range of ground movements, such as rockfalls , deep-seated slope failures, mudflows , and debris flows. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event such as a heavy rainfall , an earthquake , a slope cut to build a road, and many others , although this is not always identifiable.

Slope instability along transportation routes and in mountain valleys poses dangers and is a source of considerable economic losses. Large numbers of fatalities can be expected from very rapid and extremely rapid landslides which move faster than a person can run.

Landslides can cause seismic disturbances; landslides can also result from seismic disturbances, and earthquake-induced slides have caused loss of life in many countries. Slides can cause disastrous flooding, particularly when landslide dams across streams are breached, and flooding may trigger slides. Slope movement in general is a major process of the geologic environment that places constraints on engineering development. In order to understand and foresee both the causes and effects of slope movement, studies must be made on a regional scale, at individual sites, and in the laboratory.
What is a landslide? A landslide is defined as the movement of a mass of rock, debris, or earth down a slope due to gravity. The materials may move by falling, toppling, sliding, spreading, or flowing. What causes a landslide? Almost every landslide has multiple causes.
This work is based on a structuralexploration of the landslide areas mainly by seismicmethods. Information about the status of deformationis obtained by comparison of the actual topographywith a reconstruction of the original topography, byGPS, and by SAR interferometry. Geologic andgeomorphological evidence, as well as relevantinformation from other geo-scientific disciplines, isconsidered. The Finite Element Method is used to modelthe initial phase of a mass movement. Later on thismodeling will be extended to the quasi-stationarycreep phase and the transition from creeping to rapidsliding. Four large landslides within the crystalline rocks ofthe Eastern Alps have been investigated since

Geographers are commonly called upon to diagnose the causes of natural disasters and provide guidance for policy makers. Causes were sought on a 7. Individual landslides were surveyed along with a suite of potential environmental indicators. These results show that the numbers of landslides on the roadbed were not unusual, so research switched to exploring factors that may have enhanced their volumes. Local opinion considers that the major causes were human impacts, especially recent urban development, or geological weaknesses. However, results show that human impacts such as building construction, deforestation, and the collapse of agricultural terraces were associated with smaller landslides, while geological factors showed no significant correlations with landslide volume.

It can be rapid, very slow, or in between. It can involve large or small areas and volumes of material. The principal types of movement are falling, sliding, and flowing, but combinations of these are common. As human impact on the land increases, we both cause more landslides and are increasingly affected by natural ones. In some parts of Pennsylvania, landslides are a significant hazard. Southwestern Pennsylvania has by far the highest concentration of landslides. Outside that region, high susceptibility areas are mostly smaller and have more varied geology and topography.

Ему не было нужды выискивать Беккера в толпе, выходящей из церкви: жертва в ловушке, все сложилось на редкость удачно. Нужно только выбрать момент, чтобы сделать это тихо. Его глушитель, самый лучший из тех, какие только можно было купить, издавал легкий, похожий на покашливание, звук. Все будет прекрасно.
С ужасом девушка увидела, что сумка застряла в двери. Она наклонилась и что было сил потянула ее, стараясь высвободить застрявшую часть. Затуманенные глаза Беккера не отрываясь смотрели на торчащий из двери кусок ткани.
Он присмотрелся внимательнее. Офицер выключил свет, и комната погрузилась в темноту. - Подождите, - сказал Беккер. - Включите на секунду.
