According to data from the United States Geological Survey (USGS) and Türkiye’s Disaster and Emergency Management Authority (AFAD), the quake was felt at differing intensities in each district.
The epicentre of the earthquake, which registered a magnitude of 6.2, was located offshore near Silivri. The seismic waves were strongest in Istanbul’s western districts, gradually diminishing in intensity toward the eastern parts of the city.
