how is a earthquake formed

how is a earthquake formed ? Earthquakes occur in fractures called the fault of the Earth's crust. The tiles are broken under high pressure (stress, jamming or bending) because of the fragile feature of the rock. The gradual movement of the tensile plates occurs at different points of the Earth's crust. Earthquakes are elevated enough to cause a sudden movement of tension in a rocky area. This movement can create a new fault with the fracture of the rock at its weakest point or sliding along the existing fault of the rock. As a result, an extraordinary large-scale energy is revealed by the stress of tension. This energy creates a vibration earthquake in the surrounding rock masses. Earthquake-causing refraction or slippage to the point where the quake begins, the area that coincides directly above this point is called Earthquake Center.


Bending of rocks


To better understand the effects of tension on the rocks along a fault, hold the two ductility sideways and think that the fan passes through the point where these two "rocks" are worth each other. Slide a section of the rock into One Direction, the other in the opposite direction, or move the sponges slowly, rubbing them in opposite directions. You'll see that sponges don't move easily. The pressure will reach a certain point and change the shape by bending the sponges until it is suddenly slipped.


Shock waves


The vibrations of an earthquake pass through the depths of the Earth. Scientists have named them shock waves or seismic waves (the seismic word derives from the word "seismos", which means "trembling world" in Greek). Different types of shock waves emitted from the earthquake room create different vibrations in the rocks they pass through.

The main two types of shock waves are called primary and secondary. The primary or P waves compress the rocks they pass through and gerer. The secondary or S waves move the rocks up and down and both sides simultaneously. Other types of shock waves, called surface waves, have a different impact on their creative effects. These are not seen in every earthquake. However, when seen, they can cause damage to the earthquake center, even in very distant places.



Fault Belts

There are many faults in the Litosferde. They extend to different angles in the underground and may not reach the surface. Many of the faults are very old. Since they lost their activities over time, they have not shown any movement for millions of years. The most part of the fault movement is revealed at the highest level of stress accumulation or near the slab boundary. The movements on the fault can be gradual, as it could be instantaneous, which would lead to earthquakes. The areas where the tiles are moving are called the active fault belt.
