Geologists and experts are providing varying assessments of seismic risks across different regions of Turkey. In the Marmara region, debate exists regarding fault line activity. Professor Naci Görür noted that recent small-scale activity on the Küçükkuyu Fault indicates tension in the southern branch of the North Anatolian Fault, though he maintains the primary risk remains with the northern branch. Conversely, Professor Şener Üşümezsoy challenged these views, arguing that certain structures are not active and suggesting a potential earthquake in the Marmara Sea would not exceed magnitude 6.5.

In Bursa, scientific discussions have identified a 94-kilometer fault system stretching across the Bursa plain. Experts warned that this system has the potential to generate an earthquake of up to magnitude 7. Researchers emphasized the importance of using historical records and geological data to improve modern urban planning and disaster management strategies.
