Seismologist professor at the Center for Geological Research (GFZ), based in Potsdam, Germany. Dr. Marco Bohnhoff drew attention to the importance of every step to be taken regarding an earthquake in a megacity like Istanbul. According to Bohnhoff closely examines the mobility of faults in Turkey for a long time, generally speaking, a very difficult task to prepare a big city like the Istanbul earthquake. Bohnhoff said: “What has been done will never be completely perfect. What can be done to protect people is to strengthen the structure of buildings. This is what is being done right now. In a city with more than 1 , 2 million buildings, this is not an easy task. A lot of research on this topic. And increasing efforts to prepare the city for an earthquake, “he said.
“ISTANBUL SHOULD BE PREPARED FOR AN EARTHQUAKE ON 7”
If the 5.8 magnitude Istanbul earthquake that took place on September 26, 2019 was a harbinger of a possible severe earthquake expected in Marmara, it was widely discussed. According to Bohnhoff, this earthquake did not have a triggering effect.
According to the report by Deniz Barış Narlı of Deutsche Welle Turkish, the German seismologist said: “This earthquake occurred at the very edge of the fault segment that was completely compressed. As far as we know from our studies so far, this earthquake did not increase the seismic risk. . However, on the other hand, it did not reduce energy here. For this reason, we must be prepared for an earthquake of magnitude between 7 and 7.4 around Istanbul, “he said.
Bohnhoff said that it is very difficult to predict and warn an earthquake in the Marmara region through major earthquakes, as the fault is very close to the city. We are closely following the small earthquakes that can precede big earthquakes. There are efforts in this regard. These can be used as a signal for the future of a major earthquake. But now it is too early to implement this as an advanced prediction system. “
earthquake with the Turkish authorities, expressing that they are working on a system that could alert Bohnhoff in advance, “the Turkish authorities in this regard, we are testing our and our partners. Such a system with an optimistic vision – that we are talking about of an earthquake forecasting operating system – next “It can be tested and implemented in years. But this is a very complex task and if we look at examples of this in the world, there are very few such systems in place. “
