◇Anchor> I heard that the scale of the fault that caused the first earthquake reached 200 km. Because it is so large, it is said that it woke up the sleeping fault around it.
◆Reporter> In the case of the East Anatolia fault, two tectonic plates and three tectonic plates meet. That’s the Arabian version and the Anatolian version. Because the Turkiye region is on top of the Anatolian plate. and the African version. This is where the energy continues to build up as the three tectonic plates collide. Where energy continues to build up, there should be a strong earthquake, but in the meantime, it has slowed down. There are no examples of strong earthquakes. That’s why seismologists say this area is dangerous. It was predicted that a big earthquake would happen at any time.
If so, it is a story that a lot of underground energy continued to accumulate around it, not just the East Anatolia fault. But this time, a strong earthquake of magnitude 7.8 occurred on the East Anatolia fault. Then, that energy radiates out in all directions. However, another fault that we did not know about has already accumulated energy, and an earthquake could occur at any time. A fault that could cause a magnitude 7.5 earthquake occurred. You can look at it like this.
◇Anchor> Then, it would be important to predict where the next earthquake might occur, but looking at cases where earthquakes have occurred in the past, it is said that strong earthquakes occurred while moving west. So, next time it could be Istanbul. There is also such a prospect. How do you see it?
◆Reporter> Originally, there were many earthquakes in the North Anatolia fault zone. At that time, there were five earthquakes of magnitude 7 or greater in the last 24 years. The earthquake usually occurred in the North Anatolia fault zone, not the East Anatolia fault zone where the earthquake occurred this time. Also see the cycle. You can see that this side is where much stronger energies are continuously accumulated. Most of what you see now is almost linear, isn’t there an earthquake?
◇Anchor> Are you moving west?
◆Reporter> North Anatolia fault. So, it can be seen that the energy ejected from one fault continues to move while having an effect, so in the case of Turkiye seismologists, it can fly about once more in the North Anatolia fault zone. And predictions continued that the East Anatolia fault zone, which had been quiet for a while, was also dangerous. So this time, the East Anatolia fault zone has been resolved. But still, another aftershock remains to be seen. The Northern Anatolia fault zone also happened once in 2000 in the case of an earthquake that caused the most recent damage. It happened once in 1999.
However, as it continued to move westward, the accumulated energies were erupting. If so, it is highly likely that another earthquake could occur in the North Anatolia fault zone. So, usually, the places that Turkiye seismologists have been paying attention to are the Northern Anatolian fault zone near Istanbul, and the coastal cities of the East Anatolia fault zone. I was pointing out these two things.
