In context

How big was it, and why here?

Energy released

60 kg of TNT

That is about 1/250,808 of the Hiroshima bomb. A magnitude 5.0 releases about 7,943 times more energy.

Tectonic setting

169 km

from the nearest mapped plate boundary, between the Aegean Sea and Eurasian plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.

Depth: shallow

15 km

Shallow earthquakes (under 70 km) produce the strongest surface shaking for their size, so they are the ones most likely to cause damage near the epicenter.

After the main event

Aftershocks within 50 km

USGS and EMSC list 3 M2.5+ earthquakes within 50 km since this event; the largest was M3.7 on September 20, 2026. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
