M5.4 Earthquake 70 km WSW of Lithakiá, Greece — December 15, 2025
2025-12-15 23:41:47 UTC (2025-12-15) · approx. 12:41 AM UTC+1 local
Felt by 1 person across nearby locations.
On December 15, 2025 at 23:41 UTC, a magnitude 5.4 shallow crustal earthquake struck 70 km WSW of Lithakiá, Greece, at a depth of 16.4 km and coordinates 37.4097°, 20.1314°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.6 (light). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 81 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 449, placing it among routine seismic activity. The nearest populated place is Ambelokipoi (population 1,606).
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 Greece, a region characterized by the Hellenic subduction zone, where the African Plate subducts northward beneath the Aegean at roughly 35 mm per year. The nearest mapped fault system is the Hellenic Trench. View all earthquakes in Greece.

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 Greece had earthquakes this big before?
The largest recorded earthquake in Greece was the M8.5 Crete earthquake of June 29, 1303. Today's magnitude 5.4 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
