WHERE ARE 7 MOST RISKY DISTRICTS FOR ISTANBUL EARTHQUAKES?
After the Kahramanmaraş and Hatay based earthquakes, the structures in Istanbul also became a subject of curiosity. So, does the site or apartment where you live comply with the earthquake regulations? Which districts of the megacity are at risk? Here are the details.
Turkey iResidence, “After the 2nd major earthquake that was centered in Kahramanmaraş, many people are wondering whether the house in Turkey they live in is durable. The house in Besiktas that is 200.000 USD can become down value to 20.000 USD in 1 day.”
Mar 2023 Prof. Dr. flash explains: Istanbul has capacity of two 7-magnitude earthquakes in 1 year.
So, are the buildings and sites where you live in compliance with the earthquake regulations? According to experts, the ‘risky structure detection report’ of the main structures and ‘earthquake regulations’ should be examined.
“There are about 1 million risky structures in Istanbul, especially when we look at the structures built before the year 2000,” experts who say that it is very important to carry out inspections of these structures every year.

SO WHICH DISTRICTS IN ISTANBUL ARE AT RISK IN THE EVENT OF A POSSIBLE EARTHQUAKE?
Districts such as Avcılar, Fatih, Zeytinburnu, Esenler, Küçükçekmece, Tuzla, Beylikdüzü are too risky. Therefore, an action plan for the structures is necessary.
In Istanbul, the reporting of earthquake risk determinations of the main structures by the municipalities and the supervision of these structures are of great importance.

RAPID SCREENING TEST FOR BUILDINGS IN ISTANBUL: THERE ARE 76 THOUSAND APPLICATIONS
On the other hand, rapid screening tests conducted by the Istanbul Metropolitan Municipality Earthquake Risk Management and Urban Improvement Department in buildings have also gained momentum. The Head of the Department, said, “As of today, we have received a total of 76 thousand applications. We will respond to all of these. Similar methods are being applied in many countries of the world,” he said.
Rapid screening tests conducted by Istanbul Metropolitan Municipality for 3 years have gained momentum after the Kahramanmaraş and Hatay based earthquakes. The rapid scanning method preferred by those who want to analyze the risk status of the buildings they live in in Istanbul was carried out today at the 6 storey, 12 apartment unit building in Bakırköy. Earthquake Risk Management and Urban Improvement Department teams made examinations through the column in the house they entered.
Head of the Earthquake Risk Management and Urban Improvement Department, who provided information about the studies carried out, We visited 107 thousand buildings during this period and asked for permission to inspect, but by this time 29 thousand buildings have been allowed for inspection. As of today, we have received a total of 76 thousand applications. We will respond to all of these. There has been a lot of sensitivity after the devastating earthquakes. We will evaluate these applications according to the order of application and examine all the buildings,” he said.

IT CANNOT BE APPLIED FOR BUILDINGS ABOVE 10 FLOORS
Head of the Department, “This method cannot be applied to buildings above 10 floors. structures after 2000 could not apply, at this point we also received applications, as of this week we will take these applications into consideration. An application can be made. the buildings built before the year 2000 constitute our fragile building stock and we will evaluate the applications by prioritizing these structures. There was also an intense demand for tenants. We have reviewed our system accordingly. We will also receive applications from tenants,” he said.

IF THE STRUCTURE IS IN THE RISK GROUP, WE PROVIDE INFORMATION
Reminding that it was understood that 318 thousand buildings did not have earthquake load-bearing capacity as a result of rapid scans, was said, “We have set our rental assistance at 4 thousand 500 to speed up the urban transformation processes of these buildings and ensure their rapid evacuation. Both owners and tenants in these buildings will be able to benefit from our rental support. our transactions related to the 318 thousand building had been going on for several months. We demolished the first one 3 days before the earthquake. We also made building-by-building notifications about other buildings. We organized a joint meeting with the district municipalities. We will complete these studies by rapidly expanding our team. With the rapid scanning method we are currently conducting, the building inspection is the stage before the risky structure is declared within the scope of the law No. 6306. After that, if the structure is in the risk group, we are already making this information to the residents of Istanbul.
COMPREHENSIVE ANALYSIS PROPOSAL FOR CLASS D AND E
Director of Istanbul Urbanism Workshop, said, “We have just completed a quick scan process with Istanbul Technical University in our building. We’ve collected the building’s data. First, we removed the plaster, determined the number of irons with our X-ray device. After the stripping operations, we took a piece of concrete down to the iron and measured the corrosion of the iron inside. Then we measured the hardness of the concrete with the schmidt hammer. Then we draw a general static relay of the building. After that, we will analyze all the data in our office and determine the earthquake safety rate of the building. There are 5 classes here as A, B, C, D, E class. High-risk buildings of class D and E. We recommend that the D and E class buildings be subjected to a comprehensive analysis. We see these as risky. we recommend that a comprehensive analysis be carried out in accordance with law No. 6306. If these buildings are risky as a result of this analysis, they should be strengthened or renovated,” he said.

THERE IS AN UNEASINESS IN EVERY HOUSEHOLD
A Turkish citizen, who lives as a tenant said, “People living on the beach side are experiencing the same anxiety in every household right now. Everyone wants to get out to a safer place. We are listening to the professors. Prices have also doubled. it’s a 40-year-old building. We applied to Istanbul Metropolitan Municipality 3-4 days ago, they returned quickly. We will also take quick action according to the risk report. I decided and applied individually. It is enough for one person from an apartment to apply. We are thinking of going to a safe place in Istanbul in case of risky exit, if rent or house prices in Istanbul go up at exorbitant prices, we will plan to change cities.
