Major earthquakes on Monday morning, February 6, 2023, in southern Turkey and northern Syria, caused a lot of casualties and killed
thousands of people in the central area
Rescue forces are searching for the debris of buildings to find survivors who are facing severe winter cold, as well as power outages and
in the Syrian border area
damage in Syria, as well as in Iraq, Lebanon, Palestine, Egypt and Cyprus, and even parts of western Iran
Just nine hours after this earthquake, the second earthquake with a magnitude of 7.5 occurred on a different fault trend - with the
Anatolian fault system.Historical earthquakes along the eastern Anatolian Fault EAFZ system are notable on November 29, 1114, with a
magnitude of 7.8, March 28, 1513, with a magnitude of 7.4, and March 2, 1893, with a magnitude of 2
the southwestern end of this fault system, which ended on the morning of February 6.TectonicsThree main tectonic plates (Arabian, Anatolia /

This includes the transition of the Anatolian block to the west, at a speed of approximately 25 mm per year compared to Eurasia, in order to

The westernmost earthquake on August 17, 1999, was the M7.6 Izmit earthquake near the Sea of Marmara, which killed about 17,000
people.Earthquake seismicityThere are three main fault zones in Turkyie called the Eastern Anatolian Fault (EAF), North Anatolian Fault
A severe earthquake in 2003 in Bingol (MW = 6.3) occurred in the eastern intersection of EAF and NAF systems and towards the west, the
Anatolian plates in northern Turkiye
The extension of this fault on the floor of the Marmara Sea in the south of Istanbul, with a slip of about 18 mm per year and the occurrence

This EAFZ fault system is characterized by subdivisions with northeast-south-west and east-west directions, which are parallel to the
In two large earthquakes on February 6, 2023, first, an earthquake occurred in a northeast-southwest direction and then the second
of the Arabian-Anatolian plates leads to rapid changes in the velocity of the plate along the boundary, which is manifested by reducing the

In the first earthquake, the southwestern part of EAFZ was broken for 180 km; from the surface to a depth of about 20 km (in a total
accumulated energy
The second earthquake occurred 9 hours later at 13:24 local time along the east-west fault, the end of which reaches the rupture zone in the
morning of February 6, 2023, with a magnitude of 7.5.Therefore, this second earthquake, which was located 100 km from the epicenter of the
first earthquake, was not an aftershock and was the second independent earthquake.Will the next one be a strong earthquake in Istanbul? One
of February 6, 2023, there has been a big debate in public opinion and in the Turkish media about whether the next important earthquake will
be in Istanbul
Of course, if the two earthquakes of February 6, were to affect the faults in the Istanbul area, it should be said that it is unlikely that
the Marmara Sea, which passes through the city of Istanbul, has been very long
Three large historical earthquakes occurred in the North Anatolian fault zone in 474, 989, and 1766 with an estimated magnitude of about 7
It seems that with the situation in Turkiye after the earthquakes of February 6, 2023, this country, like most other middle east countries,
is unfortunately not ready for severe earthquakes near densely populated urban areas.
