M5.4 Earthquake 5 km SSE of ?çmeler, Turkey — June 28, 2020
2020-06-28 17:43:28 UTC (2020-06-28) · approx. 7:43 PM UTC+2 local
Felt by 60 people across nearby locations. Maximum shaking intensity MMI 5.0 (strong).
On June 28, 2020 at 17:43 UTC, a magnitude 5.4 shallow crustal earthquake struck 5 km SSE of ?çmeler, Turkey, at a depth of 63.0 km and coordinates 36.7481°, 28.2482°. The earthquake was reported felt by 60 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 5.0 (strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Marmaris (population 33,731).
Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 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 5.4 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 5.4 event is significantly smaller than that historical record.
