He also added , ''The earthquake is approaching in Istanbul, that's for sure. In the studies conducted, starting from the earthquakes in 1999 and with the possibility of occurring at any moment, within 30 years starting from 1999, the probability was stated to be 62 percent. Now, 23-24 years have passed. Therefore, in my opinion, the outlook for this possibility is becoming more pessimistic. Because every year, there is a 2.5 centimeter movement on the northern branch of the North Anatolian Fault due to stress buildup. Considering the stress that large earthquakes occurring in Turkey exert on the Anatolian fault zone, it is not possible for this process to last much longer."
