An earthquake struck Turkey's eastern Erzincan Province at 1:57:23 a.m. on 27 December 1939 local time with a moment magnitude of 7.8Mw and a maximum Mercalli intensity of XII (Extreme). It is the joint second most-powerful earthquake recorded in Turkey, tied with the 2023 Turkey–Syria earthquake. Only the 1668 North Anatolia earthquake was more powerful. This was one of the largest in a sequence of violent shocks to affect Turkey along the North Anatolian Fault between 1939 and 1999. Surface rupturing, with a horizontal displacement of up to 3.7 meters, occurred in a 360 km long segment of the North Anatolian Fault Zone.
