What happened
On 6 February 2023, at around 4:15 a.m. local time, a magnitude 7.8 earthquake struck south-central Turkey near the Syrian border, followed nine hours later by a second major quake, measured by different agencies at magnitude 7.5 to 7.7, roughly 95 kilometers to the north. Both struck at shallow depths of around 10 to 18 kilometers, which the US Geological Survey notes produces especially severe shaking, and the sequence affected an area of roughly 350,000 square kilometers across 11 Turkish provinces. As of 20 March 2023, the confirmed death toll had passed 57,000 people across Turkey and Syria combined, more than 50,000 of them in Turkey, making the Kahramanmaras earthquake sequence the deadliest disaster in modern Turkish history, surpassing the roughly 33,000 killed in the 1939 Erzincan earthquake.
Why it matters
The 2023 earthquake exposed how widespread construction shortcuts and weak building-code enforcement across earthquake-prone Turkish provinces had left millions of people in structures unable to withstand a major quake, triggering government prosecutions of contractors and a national reckoning over building standards that continues to shape Turkish politics and reconstruction policy years later. It stands as the most severe natural disaster in the republic's century of existence.
How we know
The earthquake's magnitude, timing, and location were measured and reported directly by the US Geological Survey's seismic monitoring network, and the death toll and public-health scale of the disaster are documented in a peer-reviewed scientific analysis published via the National Center for Biotechnology Information.
