Friend Özakın, a researcher working in the field of artificial learning and theoretical physics, put an end to his professional career in the USA for more than 20 years and returned to Boğaziçi University, where he graduated, and started a new research on artificial learning and earthquakes. Özakın’s research, from his existence newsIt is about the follow-up of “ghost earthquakes”, which we are not even narrow, with artificial learning.

Friend Özakın gave the following information about the project:

“Earthquakes do not always happen as big as we can feel, there are many small earthquakes that people do not feel and earthquake detection systems often overlook. A small earthquake leaves a ghost-like trace of its own, a whisper in the background noise. On the other hand, it is interesting. that is, small earthquakes occur much more frequently, much more often than large earthquakes. “

“MANY SMALL EARTHQUAKES HAPPEN”

“The aim of our project is to capture earthquakes that we can call such ghost earthquakes using artificial learning techniques. Faults with large earthquakes such as the North Anatolian Fault Line actually have many small earthquakes. These small earthquakes contain clues about the movement, behavior, and perhaps future of the fault. “The more earthquakes we capture and examine with high precision, the more information we can get about the fault. And we can do this without waiting for larger, less frequent and more destructive earthquakes.”

“Another benefit of earthquake detection is that it gives us the chance to get information about the structures under the ground. As earthquake waves spread through the earth, they collect traces of the places they passed. Seismologists examine these traces and learn what structures are in various layers of the earth, like taking a tomography. Catching small earthquakes that occur also contributes to our access to this type of information. “

Kandilli There are some techniques used to catch small earthquakes at various earthquake monitoring centers around the world, including the observatory. But these techniques take a lot of time and effort. That’s why we want to go beyond that. Artificial learning techniques have demonstrated outstanding success in classic detection and classification problems in many areas. Our aim is to use this approach in earthquake detection. “

“Early warning systems can have various problems. A very high sensitivity is required to warn when earthquake waves are just beginning to arrive, but such a high sensitivity often brings false alarms with it. Artificial learning shows that early warning systems can solve such problems and improve the quality of the system. there are some indications. “

“With the progress of the project, this is one of the things we are thinking of working on. If the results continue to be good, if we can clearly show that we have caught earthquakes that have not been caught, and if we can produce new information for experts working in this field, this project will achieve its purpose.”

WHO IS A FRIEND ÖZAKIN?

Friend Özakın, a theoretical physicist and machine learning researcher, graduated from Boğaziçi University in 1997 with a double major in Physics and Mathematics. He received his PhD in Theoretical Physics from the California Institute of Technology. He then conducted research on machine learning in the Computer department, and on Quantum Information Processing Technologies at Georgia Tech Quantum Institute. He then worked in a private company in Silicon Valley. Last year, just before the pandemic, with the TÜBİTAK 2232 program TurkeyHe returned to and started his studies at Boğaziçi University, where he graduated.

Within the scope of the project, Prof. Dr. Hayrullah Karabulut, Dr. Lecturer Çağrı Diner and Assoc. Dr. Working in cooperation with Özgün Konca. In addition, from Boğaziçi University Kandilli Observatory and Earthquake Research Institute, Prof. Dr. Semih Ergintav and researcher Dr. Yaman Özakın also supports the project.
