An earthquake struck Turkey's eastern Erzincan Province at 1:57:23 a.m. on 27 December 1939 local time with a moment magnitude (Mw ) of 7.8 and maximum Mercalli intensity of XII (Extreme). It is tied with the 2023 Turkey–Syria earthquakes as the most-powerful earthquake in Turkey to be recorded by instruments. However, smaller than estimates of the 1668 North Anatolia earthquake.[4] 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.[5][6] The earthquake was the most severe natural loss of life in Turkey in the 20th century, with 32,968 dead,[6] and some 100,000 injured.[7]
