Turkey is in a geographically seismic area with the country between the North Anatolian fault line running through the entirety of the landmass and the East Anatolian fault line running through the south of the country.

A timeline of major earthquakes to hit Turkey:
Erzincan, December 27 – 1939
Striking the city at 1:57 am while most of its inhabitants were sleeping, the 7.8 magnitude earthquake left almost 33,000 residents dead.
Many died because the earthquake struck in the middle of winter and a resulting blizzard and a flood made the city uninhabitable. It was abandoned and a new one was built to the north.
The region saw more magnitude 7 earthquakes and Turkey started to adopt building regulations in a bid to upgrade the safety of buildings.
Bolu-Gerede, February 1 – 1944
The powerful earthquake had a 7.4 magnitude and resulted in a knock-on effect in other towns alongside the Anatolian fault line.
Striking at 5:22 am, the earthquake left 2,790 people dead and 50,000 were destroyed or were heavily damaged.
Bingol, May 22 -1971
Bingol was nearly destroyed after a 6.9 magnitude struck at 18:44 pm in the eastern city of Turkey. More than 90 percent of the buildings were destroyed leaving much of the population homeless and almost 1,000 people dead.
Izmit, August 17 – 1999
The 7.6 magnitude earthquake struck the city of Izmit, 90km southeast of Istanbul at 3:01 am local time. The surrounding region is one of Turkey’s most important industrial regions.
It left more than 17,118 dead, 50,000 injured and upwards of 500,000 people homeless. Poor construction material was considered a factor in the high death toll.
The economic fallout was estimated to be around $6.5 billion.
Van, October 23 – 2011
Considered one of the biggest earthquakes Turkey has had in recent years, at a magnitude of 7.2.
The earthquake left 640 dead and injured almost 2,000.
Elazig, January 24 – 2020
The 6.7 magnitude earthquake struck the eastern city of Turkey earlier this year leaving 41 people dead and injuring more than 1,600 dead.
More than 400 search and rescue teams were dispatched by Turkey’s Disaster and Emergency Management Authority to the region. Turkey’s Ministry of Interior, the military and the country’s Red Crescent were mobilised in the search and rescue effort.
