M6.7 Earthquake 14 km E of Nurda??, Turkey — February 6, 2023
2023-02-06 01:28:15 UTC (2023-02-06) · approx. 3:28 AM UTC+2 local
Felt by 149 people across surrounding communities. Maximum shaking intensity MMI 7.8 (severe).
On February 6, 2023 at 01:28 UTC, a magnitude 6.7 shallow crustal earthquake struck 14 km E of Nurda??, Turkey, at a depth of 9.8 km and coordinates 37.1893°, 36.8929°. The earthquake was reported felt by 149 peopleacross surrounding communities, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.8 (severe). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 194 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 826, making it one of the more significant events of the week. The nearest populated place is Sakcagoz (population 0).
Physical scale: An earthquake of magnitude 6.7 releases seismic energy equivalent to roughly 169 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 25 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 6.7 earthquakes can continue for weeks to months 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 6.7 event is significantly smaller than that historical record.
