On January 16, 2022 at 11:48 UTC, a magnitude 5.5 shallow crustal earthquake struck 25 km SSE of Karyes, Greece, at a depth of 7.0 km and coordinates 40.0413°, 24.3610°. The earthquake was reported felt by 28 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.9 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Karyes (population 237).

Physical scale: An earthquake of magnitude 5.5 releases seismic energy equivalent to roughly 3 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.8 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 5.5 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 5.5 event is significantly smaller than that historical record.
