Every time a massive earthquake term movement of tectonic plates are always emerging. Also the term is referred to when talking about the area of an active volcano. What and how to actually move the tectonic plates?
The devastating earthquake that triggered the tsunami in Aceh in 2004 or 2011 the same Fukushima tsunami triggered by the movement of tectonic plates. The movement of tectonic plates typically release enormous energy that trigger earthquakes in the surrounding area.
It is known that active seismic zones in the world with regard to the movement of the tectonic plates. Active seismic region in the form of a fault or faults are all located in the region or the periphery of the collision of tectonic plates. What causes earthquakes facts
Also the trigger plate tectonics is the area of active volcanoes around the world. Today we recognize the so-called Pacific Ring of Fire circular from North America, Japan, Indonesia, Hawaii and back toward South America. But what did and how it’s actually the movement of tectonic plates?
Plate tectonics theory was first introduced by meteorologists geophysical and polar researchers from Germany, Alfred Wegener in 1915. Wegener pubklikasi scientific work “The Origin of Continent and Oceans” which also explains the movement of tectonic plates. He based his theory on the appearance of the geographic continents in the world and paleontological findings which support the hypothesis. German scientists have theorized that the earth’s crust consists of plates which float on the molten mass over.
Wegener’s theory initially harassed and ridiculed many of the leading geoscience expert in his day. Because, at that time there is no technology that is able to explain the phenomenon that is difficult as it is. It was only in the 1950s, about 20 years after Wegener died provable theory of plate tectonics.
Suddenly, the mystery of the earthquake, volcanology activity and the Earth’s crust movements unfold as plate tectonic theory can explain the cause. Earthquake typically occur in subduction zones where two or more tectonic plates meet.
Plate movement is very slow, sometimes only one centimeter per year, but in a cumulation of hundreds or thousands of years, the energy of the movement can be very powerful if released immediately. This was a great earthquake triggers worldwide. Until now, geologists can not predict when an earthquake will occur.
With Wegener’s based on the theory of “continental drift” or movement of tectonic plates, it is evident that the Earth is a dynamic planet. The core is composed of hot molten rock, which floats on top crust thick layer only a few tens of meters to tens of kilometers.
Collision or separation of two or more tectonic plates, for billions or hundreds of millions of years ago formed the morphology of the planet. About 300 million years ago in the Carboniferous to Jurassic Earth there is only one giant continent called Pangea, which is a merger of two great continents Laurussia and Gondwana.
About 230 million years ago in the Triassic first supercontinent Pangea broke and about 150 million years ago formed the morphology of the continent as it is today. In the movement of tectonic plates over hundreds of millions this year also Himalayas that was once the basis of the ocean which is then lifted to a height of 4,000 meters. The Andes Mountains, and also the circuit Aalpina Pacific ring of fire also formed due to tectonic plate dynamics.
Geologists predict within the next 300 million years, due to tectonic plate movement, will form a new giant continent called Pangea Ultima.
