Özet

The study briefly describes the February 6, 2023 Kahramanmaras-Turkiye earthquake region's past and current seismotectonic characteristics and use several New Generation Attenuation (NGA) equations to discuss some big ground motion records that occurred on February 6, 2023. Over 500 different worldwide NGA equations in the literature are reviewed. Only seven of them are selected due to the lack of earthquake data obtained from the AFAD (The Disaster and Emergency Management Presidency of Turkey). The available data are epicentral distance, moment magnitude, focal depth and . The results showed that the most of records did not fit the NGAs and interestingly did not decrease as the epicentre increase. Such figure is not expected because the Peak Ground Acceleration (PGA) is expected to drop as the recording station is further from the fault plane. This study aims to discuss some possible reasons of why the records did not fit the NGA equations and briefly discuss the earthquake region.
