One of the most striking statements after the earthquake was Prof. Dr. Cenk Yaltırak did it and said that Turkey’s earthquake maps and scenarios are both wrong.
Cansu Camlibel from T24made an important interview within the scope of the current situation and future risks. This interview is from ITU Geological Engineering Department Professor Doctor Cenk Yaltırak was done with. Yaltırak’s most important statement is “The danger map on which the earthquake regulation is based is dangerous” it happened. Çamlıbel asked Yaltırak the following questions about this and got some pretty surprising answers: ”

-Then earthquake regulations are also problematic, right?
The hazard map on which the earthquake regulation is based is a dangerous map. Because that map puts apples, pears and plums in the same place and takes their average weight as a statistic. Then the probability of encountering a quince is once every 2500 years. Such a classification cannot be made.
– Since it is a very important issue, I would like to record it clearly by asking again. The earthquake hazard maps of the country are wrong, and the earthquake regulation based on them is also wrong. Are you saying this?
Yes. The maps are also wrong, the scenarios that work on the maps are also wrong.
– Today, we are again discussing the builders who built buildings and buried thousands of people without even complying with the regulations that you call dangerous. But what you said makes me think: Thinking that I live in a building that complies with the current earthquake regulations, we can become apprentices?
You are calculating all of them according to 1, 1.5 came to this, this was destroyed. What will you do?
– On your map, even if the buildings are side by side, we see that the acceleration can go differently for the two, right?
We see right. That’s why I say; earthquake hazard maps should cease to be probabilistic hazard maps. For example, there was an Erzincan earthquake on the North Anatolian fault. On the danger map, the Erzincan region is still red. But there will be no earthquakes there for 200 years. It’s over. In order for an earthquake greater than 7 to occur there again, the repetition period of that fault must be exceeded.
– Well, here is another topic that has been discussed a lot. Will this great fault movement there trigger or affect the fault system in Marmara?
It doesn’t matter. Let’s say there are 7 buckets in this room. There are also buckets in Ufuk Hoca’s room ahead in the corridor. Are you asking me if the buckets in Ufuk Hoca’s room overflow when the buckets here overflow? It doesn’t matter, that’s another place. You can’t go around the world like dominoes by connecting these faults.
As we always say, Turkey is a country of great earthquakes and different studies and analyzes need to be done on this subject. Istanbul-focused studies are of great importance, especially since there is an expectation, the detailed report prepared by IMM on this subject is directly here is in our article.
