Periadriatic Fault System
The Periadriatic Seam (or fault) is a distinct geologic fault in Southern Europe, running ''S-shaped'' about from the Tyrrhenian Sea through the whole Southern Alps as far as Hungary. It forms the division between the Adriatic plate and the Eurasian plate. Tectonics and geology Within the Eastern Alps, the line marks the border between the Central Eastern Alps and the Southern Limestone Alps. In the Western Alps it forms the division between the southern Apulian foreland and the central crystalline zones of the Alps. Continental collision is still going on, with the Apulian and Eurasian plates still converging. The central zones of the Alps are rising too, causing vertical slip along the fault. The result is the set of major fault zones collectively named Periadriatic Seam. Movement along the Periadriatic Seam is the cause for the earthquake zone between Vienna and Friuli. The last destructive earthquake happened in Friuli in 1976. The uplift caused violent erosion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geologic Fault
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A '' fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can b ...

Earthquake
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Karawanks
The Karawanks or Karavankas or Karavanks (; , ) are a mountain range of the Southern Limestone Alps on the border between Slovenia to the south and Austria to the north. With a total length of in an east–west direction, the Karawanks chain is one of the longest ranges in Europe. It is traversed by important trade routes and has a great tourist significance. Geographically and geologically, it is divided into the higher Western Karawanks and the lower-lying Eastern Karawanks. It is traversed by the Periadriatic Seam, separating the Apulian tectonic plate from the Eurasian Plate. Near the summit of the Dreiländereck (1,508 m) is the tripoint of the three countries: Austria, Italy and Slovenia. Geography The Karawanks form the continuation of the Carnic Alps east of the Slizza stream near the tripoint of Austria, Slovenia and Italy at Arnoldstein. They are confined by the Drava Valley in the north (called ''Rosental/Rož'') and the Sava in the south, separating it from the ...

Pohorje
Pohorje (), also known as the Pohorje Massif or the Pohorje Mountains (, ''Bacherngebirge'' or often simply ''Bachern''), is a mostly wooded, medium-high mountain range south of the Drava River in northeastern Slovenia. According to the traditional AVE classification it belongs to the Southern Limestone Alps. Geologically, it forms part of the Central Alps and features silicate metamorphic and igneous rock. Pohorje is sparsely populated with dispersed villages. There are also some ski resorts. Geography Pohorje is an Alpine mountain ridge with domed summits south of the Drava. It roughly lies in the triangle formed by the towns of Maribor (to the east), Dravograd (to the west) and Slovenske Konjice (to the south). To the northwest, it is bounded by the Mislinja River, to the south by the Vitanje Lowlands (), to the east it descends to the Drava Plain () and to the southeast it descends to the Pohorje Foothills ().

Pannonian Basin
The Pannonian Basin, with the term Carpathian Basin being sometimes preferred in Hungarian literature, is a large sedimentary basin situated in southeastern Central Europe. After the Treaty of Trianon following World War I, the geomorphological term Pannonian Plain was also used for roughly the same region, referring to the lowlands in the area occupied by the Pannonian Sea during the Pliocene Epoch, however some consider the term "Pannonian Plain" not only unhistorical but also topologically erroneous. Terminology The term Pannonian Plain refers to the lowland parts of the Pannonian Basin as well as those of some adjoining regions like Lower Austria, Moravia, and Silesia (Czech Republic and Poland). The lands adjoining the plain proper are sometimes also called ''peri-Pannonian''. In English language, the terms "Pannonian Basin" and "Carpathian Basin" may sometimes be used synonymously, although the latter holds an irredentist Hungarian connotation. The name "Pannon ...

Tectonic Uplift
Tectonic uplift is the orogeny, geologic uplift of Earth#Surface, Earth's surface that is attributed to plate tectonics. While Isostasy, isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of Thrust tectonics, crustal thickening (such as Mountain formation, mountain building events), changes in the density distribution of the crust and underlying Mantle (geology), mantle, and flexural support due to the bending of rigid lithosphere. Tectonic uplift results in denudation (processes that wear away the earth's surface) by raising buried rocks closer to the surface. This process can redistribute large loads from an elevated region to a topographically lower area as well – thus promoting an isostatic response in the region of denudation (which can cause local bedrock uplift). The timing, magnitude, and rate of denudation can be estimated by geologists using pressure-temperature studies. Crustal thickening C ...

If an erosional hole is created in the nappe that is called a window. A klippe is a solitary outcrop of the nappe in the middle of autochthonous material. A tectonics, tectonic window, or fenster (lit. "window" in German language, German), is a geology, geologic structure formed by erosion or normal faulting on a thrust fault, thrust system. In such a system the rock mass ( fault (geology), hanging wall block) that has been transported by movement along the thrust is called a nappe. When erosion or normal faulting produces a hole in the nappe where the underlying autochthonous (i.e. un-transported) rocks crop out this is called a window. Klippen are also a feature near windows. The klippe is the remnant portion of a nappe after erosion has removed connecting portions of the nappe. This process results in an out ...

Hohe Tauern Window
The Tauern Window is a geological structure in the Austrian Central Eastern Alps. It is a window (in German ''fenster'') in the Austroalpine nappes where high-grade metamorphic rocks of the underlying Penninic nappes crop out. The structure is caused by a large dome-like antiform in the nappe stacks of the Alps. The relatively hard rocks of the Tauern Window are more resistant to erosion, so the window has a high relief. The mountain chains thus formed are called the Hohe Tauern. Most of Austria's highest mountains are in the Hohe Tauern, among them the Großglockner (3798 m) and Großvenediger (3674 m).

Erosion
Erosion is the action of surface processes (such as Surface runoff, water flow or wind) that removes soil, Rock (geology), rock, or dissolved material from one location on the Earth's crust#Crust, Earth's crust and then sediment transport, transports it to another location where it is deposit (geology), deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by Solvation, dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and Wind wave, waves; glacier, glacial Plucking (glaciation), plucking, Abrasion (geology), abrasion, and scour; areal flooding; Aeolian processes, wind abrasion; groundwater processes; and Mass wastin ...
