M5.7 Earthquake 24 km ENE of Nurda??, Turkey — February 6, 2023
2023-02-06 01:26:50 UTC (2023-02-06) · approx. 3:26 AM UTC+2 local
Maximum shaking intensity MMI 8.2 (violent).
On February 6, 2023 at 01:26 UTC, a magnitude 5.7 shallow crustal earthquake struck 24 km ENE of Nurda??, Turkey, at a depth of 10.0 km and coordinates 37.2252°, 37.0001°. The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 94 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 650, making it a moderate-impact event. The nearest populated place is Sakcagoz (population 0).
Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Turkey, a region characterized by the North Anatolian Fault, a 1,500 km transform boundary driven by the westward extrusion of the Anatolian microplate. The nearest mapped fault system is the North Anatolian Fault. View all earthquakes in Turkey.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.7 earthquakes can continue for days to weeks and gradually diminish over time.
Has Turkey had earthquakes this big before?
The largest recorded earthquake in Turkey was the M7.8 Kahramanmaraş earthquake of February 6, 2023. Today's magnitude 5.7 event is significantly smaller than that historical record.
