Prof. Dr. Ahmet Ercan stated that the earthquake that occurred in the morning off the coast of Büyükçekmece, Istanbul, is an aftershock of 6.2, expressing that there is no cause for concern. Ercan, who warned about the differing magnitudes reported by AFAD and Kandilli, said, "They should come together as soon as possible to agree on the seismic velocity structure of the Earth's crust and use the same model."

İstanbul woke up to an earthquake again. An earthquake occurred off the coast of Büyükçekmece at 07:18. Although the magnitude of the earthquake was not large, it caused fear among Istanbul residents who are waiting for the Marmara earthquake.
"THERE IS NO REASON TO BE CONCERNED"
Geophysicist Prof. Dr. Övgün Ahmet Ercan, in his assessment of the earthquake, stated, "An M4.1 earthquake occurred at a depth of 13 km off Kumburgaz at 07:18, which is an aftershock of M6.2. There is no reason to be concerned."
"STRESS FIELD CHANGES CONTINUE"
Earthquake expert Prof. Dr. Naci Görür commented on the earthquake, saying, "This morning, a 4.1 earthquake occurred at a depth of 13.6 km in the Kumburgaz Fault zone of KAF. Stress field changes continue in this zone. With love," he expressed.
WARNING FROM AHMET ERCAN
Prof. Dr. Ercan warned about the discrepancy between the earthquake magnitudes reported by AFAD Earthquake Department as 3.8 and Kandilli Observatory as 4.1. Ercan stated, "Kandilli Observatory and AFAD geophysicists should come together as soon as possible to agree on the seismic velocity structure of the Earth's crust and use the same model. Otherwise, having two separate reputable geophysical observatories in the same country providing different earthquake characteristics for the same earthquake is not suitable for contemporary geophysical science," he expressed.
