Reason behind small earthquakes in different places recently

After Kahramanmaraş, many of our provinces were rocked by new earthquakes. Some of these provinces were Malatya, Hatay and Osmaniye, which were badly damaged in the previous earthquakes.
After Kahramanmaraş, many of our provinces were rocked by new earthquakes. Some of these provinces were Malatya, Hatay and Osmaniye, which were badly damaged in the previous earthquakes. However, the earthquake spread and Regions such as the Mediterranean and the Aegean began to shake.
Even now, if we look at the recent earthquakes, these small earthquakes, especially in the Aegean Sea and the Mediterranean Sea, as well as in our provinces in the earthquake zone, started to scare us all. So a great devastation We just left it behind.
Some of the non-destructive earthquakes we are currently experiencing, which can reach 4-5 magnitudes, are the effects of the Kahramanmaraş earthquakes.
In fact, not only did they increase in number, they also spread almost all over Turkey. He informs us all with his research on earthquakes and his posts on Twitter. Earthquake researcher Baturhan ÖğütWe asked the reasons for these earthquakes that we experienced. According to the information we received from him; The reason for these earthquakes seen in different regions of our country is the major earthquakes we experience. pressure exerted on fracture branches.
After the earthquakes in Pazarcık and Elbistan, The P wave reached the northern hemisphere within seconds. Because pressure on other fault lines and this caused earthquakes in several regions.
You can watch the seismic wave movements after the Kahramanmaraş earthquake here:
So what is this “P wave”?
Different types of waves can be seen in earthquakes. The first of these, which we just mentioned; faster moving, able to pass through anything liquid and solid, and generally non-destructive “P” waves.
At the same time, these waves are the first to reach the earth in the event of an earthquake. Because of their fast motion and ability to pass through solid and liquid objects, they can move much farther from the earthquake zone. Therefore, although the destructive effect of P waves is small, they can exert pressure on fractures and plates. Therefore small earthquakes caused by P waves in different regions can happen.
Compared to P waves Move 40% slower However, another type of wave with a more destructive effect is “S” waves. Compared to other types of waves more destructive has effects. While P waves move horizontally; P waves moves upright.
We witnessed a similar situation in the earthquake of 99, one of the greatest devastations in our history.

After the 99 earthquake, the P wave exerted pressure on the subduction zone between the Nazca Plate and the South American Plate thousands of miles away, and then Earthquakes have occurred in several regions.
To summarize it simply; P waves propagating after a large earthquake can cause interplate motion or pressure on fractures. This is like even if it is far from the earthquake zone It can cause earthquakes in different regions.
Again, according to the earthquake researcher Öğüt, the earthquakes caused by these waves up to 1 year it may take. Because the beam of stones between the faults, by exceeding the strength resistance due to pressure can cause earthquakes for some time. In fact, there have always been earthquakes in our country and unfortunately they will continue to happen.
