The 1953 Yenice–Gönen earthquake occurred at 21:06 local time (19:06 UTC on 18 March in the province of Çanakkale and Balıkesir in the Marmara Region at western Turkey. It had a magnitude 7.5 on the surface wave magnitude scale and a maximum felt intensity of IX (Violent) on the Mercalli intensity scale. It caused widespread damage, killing 1,070 and causing damage that was estimated at US$3,570,000 repair value.
The tectonics of northern and eastern Turkey are dominated by the two strike-slip fault zones that accommodate the west to southwestward movement of the Anatolian Plate relative to the Eurasian Plate and the Arabian Plate as it is effectively being squeezed out by convergence between them. The quake occurred along the Yenice–Gönen Fault, which is a southern extension of the North Anatolian Fault Zone.
The quake had a surface wave magnitude of 7.3 and it killed at least 1070; 998 of those deaths were in Yenice, with another 50 in Gönen, 20 in Çan, and 3 in Manyas. The cost of repair was estimated at US$3,570,000. Several thousand buildings were affected in the Can-Yenice-Gonen area. Damage of intensity VI occurred at Sakarya (Adapazari), Bursa, Edirne, Istanbul and Izmir. The quake was felt throughout the Aegean Islands and in much of mainland Greece, with damage occurring as far away as Crete. Shaking was also recorded in Bulgaria.
