Two earthquakes with a magnitude of 7.7 and 7.6 occurred at 04.17 in the Pazarcık district of Kahramanmaraş and at 13.24 in the Elbistan district, respectively. The earthquake, which occurred at a depth of 7 kilometers, was felt in many cities. Search and rescue efforts continue in the region, which has caused great destruction in 10 provinces. Experts evaluate the Kahramanmaraş earthquake, which is considered the biggest earthquake of the last 100 years.
The Second Great Earthquake Is An Extraordinary Event
Geophysicist Prof. Dr. Martin Mai evaluated the 7.7 and 7.6 magnitude earthquakes centered in Kahramanmaraş. prof. Dr. Emphasizing that the second major earthquake in Maraş was an extraordinary event, Mai said, “It’s a very bad coincidence,” and gave important warnings about the Marmara Fault. Addressing the expected Istanbul earthquake, Prof. Dr. Mai said, “This will happen eventually. The plates will move inch by inch and when enough pressure builds up this earthquake will happen. It is impossible to predict the exact time.” said.
prof. Dr. Mai’s messages are: The currently affected area will continue to deal with aftershocks. Unfortunately, Turkey is in a region where there is a lot of earthquake risk. Another region that worries us the most is the region in the Marmara Sea. He stated that Turkey is at risk of earthquakes and should be prepared. prof. Dr. Mai pointed out that the earthquakes in Turkey were one of the biggest in the last 100 years. At the same time, he reminded of the devastating earthquakes in the world, he said that such a disaster is seen every 10 years. Reminding the 2011 earthquake in Japan, Prof. Dr. Mai emphasized that such an event can be seen once every 10 years.
Comparison of Earthquakes in Japan and Turkey is Inaccurate
prof. Dr. Mai; While earthquakes in Japan generally occur at the bottom of the ocean, earthquakes in Turkey are non-sea earthquakes that occur as a result of the breaking of Anatolian plateaus. The earthquake mechanism and structure of these two different geographical regions are different, which affects the effects and destruction potential of earthquakes. For this reason, he stated that it would not be correct to compare the earthquakes between Japan and Turkey. Also, the laws in the construction industry in Japan are more up-to-date and sensitive than the construction laws in Turkey, which makes buildings safer during earthquakes.
An earthquake can happen anywhere at any time, but the Istanbul earthquake will happen eventually. The layers of the earth’s crust will move slowly and an earthquake will occur when the necessary pressure is established. It is impossible to know exactly when an earthquake will occur. The earthquake resistance of buildings in Istanbul should be checked and updates should be made when necessary. Earthquake simulations can also help the public and structures learn about how to prepare for an earthquake. In addition, training and information should be given about what to do in the event of an earthquake. A mass exercise is held in Japan on September 1 each year. Annual drills are a very good method to educate the public.
Anatolian Plate Moved At Least Three Meters
Carlo Doglioni, President of the Italian National Institute of Geophysics and Volcanology (INGV), spoke to the Italian newspaper Corriere della Sera about the earthquake. The scientist stated that the Anatolian plate moved at least three meters northeast-southwest relative to the Arabian plate. Pointing out that this movement took place in only 30-40 seconds, the Italian scientist emphasized that seismic activity has been very high in this region throughout history and said, “Turkey has moved.”
We Said An Earthquake Is Coming
Professor Naci Görür, as a member of the Academy of Sciences and a geoscientist, we drew attention to possible earthquakes in the Kahramanmaraş region after the Elazig earthquake in 2020 and the Zonguldak earthquake in 2022. After the Pazarcık earthquake, Görür wrote on his social media account, “As geoscientists, we’ve been saying that this earthquake is coming, and our language has grown feathers. No one even reacted to what you were saying,” he shared.
Görür said on social media after the 4.2 earthquake that occurred in Osmaniye on February 3, 2023, “The earthquake is on the Eastern Anatolian Fault Zone. We are concerned about the Çelikhan-Erkenek-Maraş section of this zone. The 2020 Elazig earthquake loaded this section from the NE end. This earthquake also forced it from the SW end, albeit small. At this end, the last earthquake was the 1998 Adana Earthquake.
Two Major Earthquakes Are Not a Very Common Situation
Assoc. Dr. Bülent Özmen, Gazi University Disaster Management Specialist: “It is not very common for two large earthquakes to occur occasionally on the Eastern Anatolia fault line. We experienced a very rare “earthquake storm” when this earthquake happened. There are 550 active fault lines in Turkey and it is not known when which one will break. This earthquake affected the faults on the right and left of the Pötürge segment. It triggered faults in the direction of Hatay and Elazig, but not any other faults. In other words, the North Anatolian fault line in and around Istanbul does not pose a risk for this earthquake to trigger those faults.”
Region The Most Dangerous Fault of the Country
Founding President of Gazi University Earthquake Research Center Prof. Dr. Süleyman Pampal stated that the Pazarcık earthquake was larger than the 1999 Gölcük earthquake. Pampal stated that the earthquake lasted about 1 and a half minutes and was more destructive and longer lasting. The Pazarcık region is the site of an earthquake that occurred in 526, which is known as a “cosmic catastrophe” by the historian, where there is information that approximately 200 to 300 thousand people lost their lives. Pampal stated that this region is the most dangerous fault in the country and has undergone a break starting from the North and moving towards the south.
Earthquake acceleration values are an indicator that measures the strength and destructive effect of an earthquake. Acceleration values are measured relative to the acceleration of gravity and usually reflect the grounding and heaving of the ground during an earthquake. The 2G acceleration value means that the earthquake is 2 times the gravitational acceleration, and this indicates that the earthquake is abnormally large. The expected acceleration values in the regulation show that this earthquake far exceeds and its destructive effect is rarely too high.
An Earthquake Of This Size Was Expected
Professor at Izmir Dokuz Eylul University. Dr. Hasan Sözbilir gave the following information; The first earthquake with a magnitude of 7.9 occurred in Erzincan in 1939 and 33 thousand people lost their lives in 52 seconds. The earthquake occurred on the southern branches of the East Anatolian Fault, as a result of the rupture of the fault segments between Malatya and Hatay. The East Anatolian Fault is Turkey’s second largest fault, and parts of the fault accumulating stress have been broken for nearly 500 years in the region of today’s earthquake. Since the earthquake generation interval of the faults is 400-500 years, an earthquake of this magnitude was expected in the scientific sense.
There Is A Seismic Migration From Eastern Anatolia Towards South
Karadeniz Technical University (KTU) faculty member Prof. Dr. Osman Bektas; He states that these earthquakes cause destructive effects on the surface and also have the potential to trigger the distribution of energy underground. This trigger may delay or advance the earthquake on some faults. There has been a seismic migration from Eastern Anatolia to the south since the 1960s and there are 3 main faults controlling the seismicity in the country: the North Anatolian, Eastern Anatolian and Southeastern Anatolian Faults. The seismicity on these faults, which started in Varto in the 1960s, passes from the North Anatolian Fault to the East Anatolian Fault, from there to the Thrust Fault and again to the East Anatolian Fault.
A Fracture About 150 Kilometers Long Occurred
Kocaeli University Geophysical Engineering Department Head Prof. Dr. Fadime Sertçelik explained; “Earthquakes left a significant impact on a large area. Along with the main shock, a 150-kilometer-long fracture occurred on the East Anatolian Fault and aftershocks continue for about 300 kilometers. Apart from where the first major fracture occurred, other faults in the area likely acted as well. The place where the earthquake took place is quite interesting, because it is located at a point where the roads meet. The place where this earthquake occurred is the Ölüdeniz Fault in the region where the two branches separated in Maraş intersect.
Aftershocks Can Last At Least 2 Years
Kocaeli University Geophysics Engineering Department lecturer Prof. Dr. Honor Peace; No geoscientist expected that such an earthquake could occur. An earthquake with a moment magnitude of 7.7 is usually caused by the rupture of two faults. prof. Dr. Barış also draws attention to the fact that aftershocks of an earthquake greater than 7 will last at least 2 years. It is an important advantage that there are 3 aftershocks greater than 6 in the first moments. prof. Dr. Barış, one of the other events that surprised us so far is that the largest aftershock of all the major earthquakes that have occurred in the last 123 years in Turkey was 6.3, but the largest aftershock of this earthquake was 6.6.
Mobility and Interaction in the Region Will Continue
Earthquake Engineering Specialist from Altınbaş University Prof. Dr. According to Zeki Hasgür, the earthquake that occurred in Elazig in 2020 occurred in the left, strike-slip fault system called the East Anatolian Fault. This fault extends from the Iskenderun Bay to the south and extends to the Dead Sea in the south. We were expecting significant earthquakes on it. Although Elazig is close to the junction areas of the North Anatolian Fault, I stated in my assessment that there would be an earthquake in the south, in Hatay and Iskenderun regions, 2 years ago after the Izmir Earthquake. There have been small earthquakes in this region in the past, but there was no major earthquake in Iskenderun and Hatay. Therefore, the movement and interaction in this region will continue.
