These earthquakes, which are said to be “unique” by earthquake experts, affected a very wide geography. According to the data, 10 of our provinces have been affected by the earthquakes in question. well how’s that be possible?
Everyone has a great surprise and a lot of question marks about what happened on February 6th. Although this chain of earthquakes affects almost half of the country, It was felt even in Egypt, It shows how wide the impact area of the earthquake is.
In fact, an animation showing how the spreading seismic waves reached America was shared the other day. This brings to mind the question of how these earthquakes affect large areas.
According to the Danish Geological Institute, the tremors in our country reached as far as Greenland.
Kahramanmaraş and Greenland are too genius to normally be mentioned in the same sentence. two unrelated geographies. Greenland is one of the landmasses closest to the North Pole.

In order to understand the answer to our question, we need to briefly and concisely address how earthquakes occur.
Under the earth’s crust, in pieces “plate” There are continents called continents. Between these plates, there are fractures that we call “fault lines”.
Earthquakes, on the other hand, are oscillations that occur when the energy accumulated in the fractures we call “fault lines” under the plates is suddenly released. This energy release is usually by rubbing against each other or fault lines overload so it happens.
Almost every major landmass and continent on Earth has its own plate. Equally gigantic fault lines between these gigantic plates. occurs. As the plates rub against each other over time, minor fault lines arises.
An earthquake can shake more than one region depending on the accumulated energy.
Let’s remember the small fault lines we talked about earlier. These small fault lines, as you will notice, cover a large part of our country, as well as between continents. they are connected to massive fault lines. For this reason, it is possible for an earthquake to trigger another earthquake in the same country or to shake an entire region at the same time.

Is there another example of this extraordinary situation in which two major earthquakes were experienced in succession in history?
In addition, depending on whether these faults are long or short, respectively more and less destructive earthquakes may occur. Because shorter fault lines are narrower, there is not much room for energy to escape. Longer fault lines can even allow more energy to escape, and if they are long enough, it can even reach the huge fault lines we just mentioned.
Therefore, the energy released in an earthquake in Kahramanmaraş and its surroundings, depending on its power, and these fault lines. using it like a highway It could affect half of our country and some neighboring countries, and the vibrations could reach as far as Greenland.
In addition, the power released in some earthquakes also varies according to whether the energy release is close to or far from the surface of the earth’s crust.
near the surface While earthquakes are more destructive, the effect and damage potential of the earthquake decreases with distance from the surface.
The reason for this is that earthquakes close to the surface prevent them. fewer obstacles and therefore less absorption of energy. For this reason, most of this energy is loaded on the surface of the earth’s crust and near-surface faults.
6 February 2023 earthquakes 10 provinces in totalin terms of population, according to the data about 13 million Impressed. While these earthquakes occurred at a depth of 7 kilometers to the surface, the 1999 Gölcük earthquake occurred at a depth of 17 kilometers to the surface. According to this data, we can conclude that the 6 February 2023 earthquakes have a more destructive power.
