That's because, based on the earlier understanding of how the Alps formed, the collision of the plates, the formation of the trench and the height of the mountain range are all linked.Furthermore, seismicity observed during the past 40 years within the Swiss Alps and their northern foreland clearly documents extension across the mountain ranges rather than the compression expected for the bulldozing Adria model.The behaviour of the Eurasian plate provides a possible new explanation. "In turn, this creates strong upward forces that lift the Alps out of the ground," Kissling explains.

Supposedly, their weight subsequently pushed the underlying continental plate downwards, resulting in the formation of a sedimentary basin in the north adjacent to the mountains -- the Swiss Molasse Plateau. "Our model is the first earthquake simulator for the Swiss Central Alps," says Dal Zilio. The most influential Alpine geologists did not easily recover from the impact, since the new global theory discarded the geosyncline model and other traditional views. This leads the researchers to believe that the formation of the Central Alps and the sinking of the trench are not connected as previously assumed.They argue that if the Alps and the trench indeed had formed from the impact of two plates pressing together, there would be clear indications that the Alps were steadily growing. The new simulations therefore improve the assessment of earthquake risk in Switzerland.Strength of tectonic plates may explain shape of the Tibetan Plateau,Bismuth Crystal “Artificially grown bismuth crystal”,Incredible moment Anak Krakatau erupts, Oct 2018,Otman Bozdagh Mud Volcano Eruption “Sep23, 2018”,SAGA GIS – System for Automated Geoscientific Analyses,ParaView “Open Source Visualization For Geoscience”,Understanding Earth’s ‘deep-carbon cycle’,Japan’s geologic history in question after discovery of metamorphic rock microdiamonds,Unearthing evidence for the origins of plate tectonics,Ancient mountains recorded in Antarctic sandstones reveal potential links to global events,Ancient mountain formation and monsoons helped create a modern biodiversity hotspot,Mechanism underlying size-sorting of rubble on asteroid Itokawa revealed,Australia’s new armoured dinosaur revealed.International study sheds new light on the transformation of the Earth’s...125-million-year-old ‘baby’ found inside fossil,Earth’s most abundant mineral finally gets an official name.

The resulting suction effect is very strong, he explains. Dal Zilio simulated the subduction zone under the Alps: the plate tectonic processes, which took place over millions of years, and the associated earthquakes. There are a few handfuls of major plates … (2020, September 17). “All of our previous observations agree with this model,” he says.The model is based on physical laws. For over 200 years the Alps have been visited by geologists. Over time, while the mountains grew higher the basin floor sank deeper and deeper with the rest of the plate.A few years ago, however, new geophysical and geological data led ETH geophysicist Edi Kissling and Fritz Schlunegger, a sediment specialist from the University of Bern, to express doubts about this theory. The Alps formed when two large tectonic plates slowly collided, pushing up the ground over tens of millions of years, creating some of the highest peaks in Europe. A new proposal attempting to solve the long-debated issue of the polarity of subduction in the Corsica-Northern Apennine system is presented.

By about 30 Ma ago, this process of subduction is so far advanced that all oceanic lithosphere has been consumed and the continental part of the Eurasian plate enters the subduction zone.This denotes the begin of the so-called continent-continent collision with the Adriatic microplate and the European upper, lighter crust separates from the heavier, underlying lithospheric mantle. Questions?ETH Zurich. This forces the subducting lithosphere to retreat northwards, causing the Eurasian plate to exert a suction effect on the relatively small Adriatic plate.Kissling likens the action to a sinking ship.

In the beginning, orthodox plate tectonic reconstructions of the Alps and western Tethys were mostly provided by “exotic” supporters, only slightly or not influenced by the Alpine inheritance. In the 18th century Swiss naturalist Johann Jakob … "So, the mechanism that sets the plates in motion is not in fact a pushing effect but a pulling one," he says, concluding that the driving force behind it is simply the pull of gravity on the subducting plate.In addition, the model simulates the occurrence of earthquakes, or seismicity, in the Central Alps, the Swiss Plateau and below the Po Valley.
“Our model is dynamic, which gives it a huge advantage,” he says, explaining that previous models took a rather rigid or mechanical approach that did not take into account changes in plate behaviour. Dal Zilio simulated the subduction zone under the Alps: the plate tectonic processes, which took place over millions of years, and the associated earthquakes. For most of this time, they wondered how mountain ranges like the Alps formed.
