On 6 February 2023, at 04:17 TRT (01:17 UTC), a Mw 7.8 earthquake struck southern and central Turkey and northern and western Syria. The epicenter was 37 km (23 mi) west–northwest of Gaziantep. The earthquake had a maximum Mercalli intensity of XII (Extreme) around the epicenter and in Antakya. It was followed by a Mw 7.7 earthquake at 13:24. This earthquake was centered 95 km (59 mi) north-northeast from the first. There was widespread damage and tens of thousands of fatalities.

The Mw 7.8 earthquake is the largest in Turkey since the 1939 Erzincan earthquake of the same magnitude, and jointly the second-largest in the country, after larger estimates for the 1668 North Anatolia earthquake. It is also one of the strongest earthquakes ever recorded in the Levant. It was felt as far as Egypt and the Black Sea coast of Turkey. There were more than 30,000 aftershocks in the three months that followed. The seismic sequence was the result of shallow strike-slip faulting along segments of the Dead Sea Transform, East Anatolian and Sürgü–Çardak faults. (Full article...)
