On November 20, 2022 at 23:24 UTC, a magnitude 5.5 shallow crustal earthquake struck near Crete, Greece, at a depth of 63.0 km and coordinates 35.8357°, 26.4319°. The earthquake was reported felt by 42 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.0 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 235 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 485, placing it among routine seismic activity. The nearest populated place is Fry (population 357).

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.

Common Questions

How strong was the magnitude 5.5 earthquake near Crete, Greece?

The magnitude 5.5 earthquake that struck near Crete, Greece on November 20, 2022 at 23:24 UTC had a depth of 63.0 km. It was felt by 42 people with maximum shaking intensity of MMI 4.0 (moderate). For context, this was a moderate earthquake that could be widely felt.

Where did the earthquake occur?

The earthquake epicenter was located at 35.8357°, 26.4319°, which is near Crete, Greece. The nearest populated place is Fry (population 357). 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.
